State Restrictions on Methyl Tertiary Butyl Ether (released in AEO2006)  

Reports and Publications (EIA)

By the end of 2005, 25 states had barred, or passed laws banning, any more than trace levels of methyl tertiary butyl ether (MTBE) in their gasoline supplies, and legislation to ban MTBE was pending in 4 others. Some state laws address only MTBE; others also address ethers such as ethyl tertiary butyl ether (ETBE) and tertiary amyl methyl ether (TAME). Annual Energy Outlook 2006 assumes that all state MTBE bans prohibit the use of all ethers for gasoline blending.

Ditertiary butyl peroxide recovery  

SciTech Connect (OSTI)

A process is described wherein a feed material comprising significant amounts of tertiary butyl hydroperoxide and tertiary butyl alcohol and minor amounts of ditertiary butyl peroxide and other impurities is charged to a reactor together with propylene and a soluble epoxidation catalyst. At least a portion of the tertiary butyl hydroperoxide is reacted in the reactor with the propylene to form a reaction product composed of unreacted feed components, propylene oxide, an additional quantity of tertiary butyl alcohol, and impurities, including a minor amount of ditertiary butyl peroxide. The improvement for recovering substantially pure ditertiary butyl peroxide from the reaction product after the reaction product is discharged from the reactor comprises the steps of: charging the reaction product to a first distillation zone and separating therein a first unreacted propylene distillate recycle fraction, charging the remaining heavier components of the reaction product from the first distillation zone to a second distillation zone and separating a second propylene oxide distillate product fraction therein charging the heavier components from the second distillation zone to a third distillation zone and separating a third distillate fraction comprising a major amount of tertiary butyl alcohol and a minor amount of ditertiary butyl peroxide, and recovering the second propylene oxide distillate fraction, the heavier tertiary butyl alcohol product fraction and the ditertiary butyl peroxide raffinate fraction.

Isobaric vapor-liquid equilibria in the system methyl propanoate + n-butyl alcohol  

SciTech Connect (OSTI)

Isobaric vapor-liquid equilibria were determined at 74.66, 101.32, and 127.99 kPa for binary mixtures containing methyl propanoate + n-butyl alcohol by using a dynamic still with vapor and liquid circulation. No azeotrope was detected. The data were found to be thermodynamically consistent according to the point to point test. Application of the group-contribution models ASOG, UNIFAC, and modified UNIFAC to the activity coefficients at the three pressures studied gives average errors of less than 10%, 11%, and 3%, respectively.

Fluctuating micro-heterogeneity in water–tert-butyl alcohol mixtures and lambda-type divergence of the mean cluster size with phase transition-like multiple anomalies  

SciTech Connect (OSTI)

Water–tert-butyl alcohol (TBA) binary mixture exhibits a large number of thermodynamic and dynamic anomalies. These anomalies are observed at surprisingly low TBA mole fraction, with x{sub TBA} ? 0.03–0.07. We demonstrate here that the origin of the anomalies lies in the local structural changes that occur due to self-aggregation of TBA molecules. We observe a percolation transition of the TBA molecules at x{sub TBA} ? 0.05. We note that “islands” of TBA clusters form even below this mole fraction, while a large spanning cluster emerges above that mole fraction. At this percolation threshold, we observe a lambda-type divergence in the fluctuation of the size of the largest TBA cluster, reminiscent of a critical point. Alongside, the structure of water is also perturbed, albeit weakly, by the aggregation of TBA molecules. There is a monotonic decrease in the tetrahedral order parameter of water, while the dipole moment correlation shows a weak nonlinearity. Interestingly, water molecules themselves exhibit a reverse percolation transition at higher TBA concentration, x{sub TBA} ? 0.45, where large spanning water clusters now break-up into small clusters. This is accompanied by significant divergence of the fluctuations in the size of largest water cluster. This second transition gives rise to another set of anomalies around. Both the percolation transitions can be regarded as manifestations of Janus effect at small molecular level.

High octane ethers from synthesis gas-derived alcohols. Final technical report, September 25, 1990--December 24, 1993  

SciTech Connect (OSTI)

The objective of the research was to develop the methodology for the catalytic synthesis of ethers, primarily methyl isobutyl ether (MIBE) and methyl tertiary butyl ether (MTBE), directly from alcohol mixtures that are rich in methanol and 2-methyl-1-propanol (isobutanol). The overall scheme involves gasification of coal, purification and shifting of the synthesis gas, higher alcohol synthesis, and direct synthesis of ethers. The last stage of the synthesis involves direct coupling of synthesis gas-derived methanol and isobutanol that has been previously demonstrated by us to occur over superacid catalysts to yield MIBE and smaller amounts of MTBE at moderate pressures and a mixture of methanol and isobutene at low pressures. A wide range of organic resin catalysts and inorganic oxide and zeolite catalysts have been investigated for activity and selectivity in directly coupling alcohols, principally methanol and isobutanol, to form ethers and in the dehydration of isobutanol to isobutene in the presence of methanol. All of these catalysts are strong acids, and it was found that the organic and inorganic catalysts operate in different, but overlapping, temperature ranges, i.e. mainly 60--120{degrees}C for the organic resins and 90--175{degrees}C for the inorganic catalysts. For both types of catalysts, the presence of strong acid centers is required for catalytic activity, as was demonstrated by lack of activity of fully K{sup +} ion exchanged Nafion resin and zirconia prior to being sulfated by treatment with sulfuric acid.

Accelerated aging of EPDM and butyl elastomers  

SciTech Connect (OSTI)

This study was composed of three parts: a post cure study to optimize final properties of an ethylene-propylene-diene (EPDM) formulation, an accelerated aging study to compare the stress relaxation behavior of a butyl and an EPDM elastomer under compression, and a cursory evaluation of a new 70 Shore A EPDM. The optimum postcure for the EPDM was found to be 2 to 4 hours at 182{degrees}C in a vacuum. The EPDM was also shown to have superior aging characteristics compared to the butyl and is recommended for use instead of the butyl material. The physical properties for new 70 Shore A EPDM are satisfactory, and the stress relaxation behavior was only slightly inferior to the other EPDM.

Identification of volatile butyl rubber thermal-oxidative degradation products by cryofocusing gas chromatography/mass spectrometry (cryo-GC/MS).  

SciTech Connect (OSTI)

Chemical structure and physical properties of materials, such as polymers, can be altered as aging progresses, which may result in a material that is ineffective for its envisioned intent. Butyl rubber formulations, starting material, and additives were aged under thermal-oxidative conditions for up to 413 total days at up to 124 %C2%B0C. Samples included: two formulations developed at Kansas City Plant (KCP) (%236 and %2310), one commercially available formulation (%2321), Laxness bromobutyl 2030 starting material, and two additives (polyethylene AC-617 and Vanax MBM). The low-molecular weight volatile thermal-oxidative degradation products that collected in the headspace over the samples were preconcentrated, separated, and detected using cryofocusing gas chromatography mass spectrometry (cryo-GC/MS). The majority of identified degradation species were alkanes, alkenes, alcohols, ketones, and aldehydes. Observations for Butyl %2310 aged in an oxygen-18 enriched atmosphere (18O2) were used to verify when the source of oxygen in the applicable degradation products was from the gaseous environment rather than the polymeric mixture. For comparison purposes, Butyl %2310 was also aged under non-oxidative thermal conditions using an argon atmosphere.

A synthesis of optically active spiro-lactones was realized starting from 2-cyclohexenone by this method.

Blended language learning in tertiary education  

Science Journals Connector (OSTI)

This paper examines the supporting and enhancing role of technology in language learning and teaching in a higher education institution in Slovenia. Despite the fact that the vast majority of foreign language teaching is still carried out in face-to-face environments, a growing extent of foreign language teaching in a number of tertiary education institutions has moved, at least partly, online. In this paper, the development of e-learning practices in Slovenia is described first, together with the evolution of computer technologies – from multimedia to the internet – and their potential for language learning and teaching purposes. Against this background, the practical application of the Blended Language Learning (BLL) experience at the Faculty of Management Koper is discussed. The paper also addresses the changing role of teachers in blended language teaching/learning environments and analyses the opinions of students who participated in a combination of Face-to-Face (F2F) and Computer-Assisted Language Learning (CALL) courses and expressed their opinions on the BLL experience in a questionnaire.

Effects of simulant mixed waste on EPDM and butyl rubber  

SciTech Connect (OSTI)

The authors have developed a Chemical Compatibility Testing Program for the evaluation of plastic packaging components which may be used in transporting mixed waste forms. In this program, they have screened 10 plastic materials in four liquid mixed waste simulants. These plastics were butadiene-acrylonitrile copolymer (Nitrile) rubber, cross-linked polyethylene, epichlorohydrin rubber, ethylene-propylene (EPDM) rubber, fluorocarbons (Viton and Kel-F{trademark}), polytetrafluoro-ethylene (Teflon), high-density polyethylene, isobutylene-isoprene copolymer (Butyl) rubber, polypropylene, and styrene-butadiene (SBR) rubber. The selected simulant mixed wastes were (1) an aqueous alkaline mixture of sodium nitrate and sodium nitrite; (2) a chlorinated hydrocarbon mixture; (3) a simulant liquid scintillation fluid; and (4) a mixture of ketones. The screening testing protocol involved exposing the respective materials to approximately 3 kGy of gamma radiation followed by 14-day exposures to the waste simulants at 60 C. The rubber materials or elastomers were tested using Vapor Transport Rate measurements while the liner materials were tested using specific gravity as a metric. The authors have developed a chemical compatibility program for the evaluation of plastic packaging components which may be incorporated in packaging for transporting mixed waste forms. From the data analyses performed to date, they have identified the thermoplastic, polychlorotrifluoroethylene, as having the greatest chemical compatibility after having been exposed to gamma radiation followed by exposure to the Hanford Tank simulant mixed waste. The most striking observation from this study was the poor performance of polytetrafluoroethylene under these conditions. In the evaluation of the two elastomeric materials they have concluded that while both materials exhibit remarkable resistance to these environmental conditions, EPDM has a greater resistance to this corrosive simulant mixed waste.

Fuel alcohol opportunities for Indiana  

SciTech Connect (OSTI)

Prepared at the request of US Senator Birch Bayh, Chairman of the National Alcohol Fuels Commission, this study may be best utilized as a guidebook and resource manual to foster the development of a statewide fuel alcohol plan. It examines sectors in Indiana which will impact or be impacted upon by the fuel alcohol industry. The study describes fuel alcohol technologies that could be pertinent to Indiana and also looks closely at how such a fuel alcohol industry may affect the economic and policy development of the State. Finally, the study presents options for Indiana, taking into account the national context of the developing fuel alcohol industry which, unlike many others, will be highly decentralized and more under the control of the lifeblood of our society - the agricultural community.

Role of alkyl alcohol on viscosity of silica-based chemical gels for decontamination of highly radioactive nuclear facilities  

SciTech Connect (OSTI)

Silica-based chemical gel for the decontamination of nuclear facilities was prepared by using fumed silica as a viscosifier, a 0.5 M Ce (IV) solution dissolved in concentrated nitric acid as a chemical decontamination agent, and tripropylene glycol butyl ether (TPGBE) as a co-viscosifier. A new effective strategy for the preparation of the chemical gel was investigated by introducing the alkyl alcohols as organic solvents to effectively dissolve the co-viscosifier. The mixture solution of the co-viscosifier and alkyl alcohols was more effective in the control of viscosity than that of the co-viscosifier only in gel. Here, the alkyl alcohols played a key role as an effective dissolution solvent for the co-viscosifier in the preparation of the chemical gel, resulting in a reducing of the amount of the co-viscosifier and gel time compared with that of the chemical gel prepared without the alkyl alcohols. It was considered that the alkyl alcohols contributed to the effective dissolution of the co-viscosifier as well as the homogeneous mixing in the formation of the gel, while the co-viscosifier in an aqueous media of the chemical decontamination agent solution showed a lower solubility. The decontamination efficiency of the chemical gels prepared in this work using a multi-channel analyzer (MCA) showed a high decontamination efficiency of over ca. 94% and ca. 92% for Co-60 and Cs-137 contaminated on surface of the stainless steel 304, respectively.

Gene therapy in alcoholic rats  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

70 70 Sept. 9, 2001 Gene Therapy Reduces Drinking in "Alcoholic" Rats UPTON, NY - Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have shown that increasing the level of a brain protein important for transmitting pleasure signals can turn rats that prefer alcohol into light drinkers, and those with no preference into near teetotalers. The findings, published in the first September 2001 issue of the Journal of Neurochemistry (Vol. 78, No. 5), may have implications for the prevention and treatment of alcoholism in humans. "This is a preliminary study, but when you see a rat that chooses to drink 80 to 90 percent of its daily fluid as alcohol, and then three days later it's down to 20 percent, that's a dramatic drop in alcohol intake - a very clear change in behavior," said Panayotis Thanos, the lead researcher. "This gives us great hope that we can refine this treatment for future clinical use."

Aging of Weapon Seals – An Update on Butyl O-ring Issues  

SciTech Connect (OSTI)

During testing under the Enhanced Surveillance Campaign in 2001, preliminary data detected a previously unknown and potentially serious concern with recently procured butyl o-rings on several programs. All butyl o-rings molded from a proprietary formulation throughout the period circa 1999 through 2001 had less than a full cure. Engineering judgment was that under curing is detrimental and could possibly lead to sub-optimum performance or, in the worst case, premature seal failure. An aging study was undertaken to ensure that suspect o-rings installed in the stockpile will retain sufficient sealing force for a minimum ten-year service life. A new prediction model developed for this study indicates suspect o-rings do not need to be replaced before the ten-year service life. Long-term testing results are reported on a yearly basis to validate the prediction model. This report documents the aging results for the period September 2002 to January 2011.

Nonlinear viscoelastic response of carbon black-filled butyl rubber and implications for o-ring aging  

SciTech Connect (OSTI)

Butyl rubber, unfortunately, has pronounced nonlinear viscoelastic behavior, which may be modelled by a separable KBKZ formalism. While these effects seem to have minimal impact on accelerated sealing force measurements, they do severely impact compression set tests. Therefore, a new test is suggested for evaluating field-return o-rings which is free from such confounding effects.

Liquid phase oxidation of thiophene compounds by tert-butyl hydroperoxide  

SciTech Connect (OSTI)

Oxidative instability problems in both shale and petroleum-derived middle distillate fuels are related to the presence of hydroperoxides. Although a good body of knowledge exists concerning the formation of peroxides in the liquid phase, relatively little is known about the reaction/decomposition pathways when other functional groups are present. One of the significant and undesirable problems is the formation of solid deposits which can plug nozzles and filters and coal heat exchanger surfaces. Deposit formation in fuels is triggered by autoxidation reactions and is closely associated with elemental oxygen and/or hydroperoxide concentration. This paper reports on the reaction between a primary autoxidation product, a hydroperoxide, and sulfur compounds of the type present in petroleum-derived middle distillate fuels. Specifically, we examine the t-butyl hydroperoxide oxidation of thiophene, 2, 5-dimethylthiophene, tetrahydrothiophene and benzothiophene in a deaerated model fuel, tetradecane, at 120{degree}C.

Fuel instability studies; Liquid phase oxidation of tetrahydrothiophene by tert-butyl hydroperoxide  

SciTech Connect (OSTI)

The reactions that lead to fuel instability are the subject of conflicting reports in the literature. Confusion results from the difficulty in relating differences in fuel composition, temperature, surface effects and dissolved oxygen content that comprise the multitude of reported studies. Model studies offer a means by chic the mechanism of an individual reaction can be related to a simple system and then extended to the more complex fuel media. This paper reports a model oxidation study of a species, t-butyl hydroperoxide under mild reaction conditions, 120{degrees}C, in a tetradecane model fuel. The major oxidation product was tetrahydrothiophene sulfoxide from the sulfide and t-butanol from the hydroperoxide. The complete suite of products is reported.

Ammoniated glycyrrhizin, butylated hydroxytoluene, and gum Arabic are generally recognized as safe (GRAS) substances that are used primarily as additives in foods. These substances were incorporated into rodent diets and fed to male rats and mice for 10 and 8 wk, respectively. The treated male mice and rats were then tested for dominant lethal effects. The mice were also tested for induced heritable translocation. Results of the rat studies indicated a statistically significant dominant lethal effect of each of the compounds tested; however, the biological significance of this response is not known. Results of the mouse dominant lethal and heritable translocation studies, on the other hand, indicated no adverse effects of the compounds tested.

Butyl rubber O-ring seals: Revision of test procedures for stockpile materials  

SciTech Connect (OSTI)

Extensive testing showed little correlation between test slab and O-ring performance. New procedures, comparable to those used with the traditional test slabs, were defined for hardness, compression set, and tensile property testing on sacrificial O-ring specimens. Changes in target performance values were made as needed and were, in one case, tightened to reflect the O-ring performance data. An additional study was carried out on O-ring and slab performance vs cure cycle and showed little sensitivity of material performance to large changes in curing time. Aging and spectra of certain materials indicated that two sets of test slabs from current vendor were accidently made from EPDM rather than butyl rubber. Random testing found no O-rings made from EPDM. As a result, and additional spectroscope test will be added to the product acceptance procedures to verify the type of rubber compound used.

Initiation Temperature for Runaway Tri-n-Butyl Phosphate/Nitric Acid Reaction

In a review of the safety basis for solvent extraction processes at the Department of Energy's Savannah River Site, a question was raised concerning the safety margin associated with a postulated accident involving a runaway tri-n-butyl phosphate (TBP)/nitric acid reaction due to the inadvertent heating of a tank. The safety margin was based on studies which showed the maximum temperature would not exceed 128 degrees Celsius compared to 130 degrees Celsius, the minimum initiation temperature for runaway reaction established in the 1950's following damaging incidents at the Savannah River and Hanford Sites. The reviewers were concerned the minimum temperature was not conservative since data for solutions containing 20 wt percent dissolved solids showed initiation temperatures at or below 130 degrees Celsius and process solutions normally contain some dissolved solids.

The model works successfully at TBP concentrations of 5 to 100 vol% and was found to be effective at predicting the extraction of HNO/sub 3/ from HNO/sub 3//NaNO/sub 3/ and HNO/sub 3//LiNO/sub 3/ solutions. Within the TBP concentration range of 5 to 30%, a single set of extraction constants was sufficient to fit extraction data. Stoichiometric activity coefficients of nitric acid in HNO/sub 3//NaNO/sub 3/ and HNO/sub 3//LiNO/sub 3/ mixtures were calculated using a model developed by Bromley.

Atmospheric chemistry of diethyl ether and ethyl tert-butyl ether  

SciTech Connect (OSTI)

The mechanisms for the Cl-initiated and OH-initiated atmospheric oxidation of diethyl ether and ethyl tert-butyl ether (ETBE) have been determined. For diethyl ether the products are ethyl formate and formaldehyde and its atmospheric oxidation can be represented by C{sub 2}H{sub 5}OC{sub 2}H{sub 5} + OH + 2NO {yields} C{sub 2}H{sub 5}OC(O)H + HCHO + 2NO{sub 2} + HO{sub 2}. The mechanism for the atmospheric oxidation of ETBE is more complex, with 80% of the reaction being accounted for in terms of tert-butyl formate and formaldehyde. The remaining 20% the authors ascribe to 2-ethoxy-2-methylpropanal. The atmospheric oxidation of ETBE can be represented by ETBE + OH + 1.8NO {yields} 0.8HCOOC(CH{sub 3}){sub 3} + 0.2C{sub 2}H{sub 5}OC(CH{sub 3}){sub 2}CHO + HO{sub 2} + 0.8HCHO + 1.8NO{sub 2}. THe subsequent atmospheric chemistry of 2-ethoxy-2-methylpropanal the authors estimate to be represented by C{sub 2}H{sub 5}OC(CH{sub 3}){sub 2}CHO + OH + 3NO {yields} CO{sub 2} + H{sub 2}CO + C{sub 2}H{sub 5}OC(O)CH{sub 3} + HO{sub 2} + 3NO{sub 2}. These results are discussed in terms of the reactivity of these compounds in urban atmospheres.

Reasons for ED attendance can be overtly and directly alcohol related such as alcohol intoxication, assaults, injuries and falls and indirectly such as child neglect, psychological problems and chronic diseases. Alcohol is often viewed as an isolated incident or factor for ED presentations but there are data that refute this perception. In ED, the priority is to treat the patient and their primary complaint, however it may be appropriate to screen for alcohol use, give advice and potentially offer an intervention to the patient. With the recent UK and Australian guidelines on reducing health risks from drinking alcohol, the ED has the ability to play an active role in reducing the harmful effects of alcohol through screening, advising and undertaking intervention as appropriate. However this cannot be achieved in isolation but within the broader political and health policy framework. There is now a growing body of literature supporting the need to make alcohol less affordable, less easy to buy and reducing alcohol advertising. Although alcohol is a legal substance, this paper concludes that examining the wider effects in physical, social and financial terms, alcohol is more dangerous than heroin. It has become an endemic problem in society affecting the individual and the whole community.

Initiation Temperature for Runaway Tri-n-Butyl Phosphate/Nitric Acid Reaction  

SciTech Connect (OSTI)

During a review of the H-Canyon authorization basis, Defense Nuclear Facility Safety Board (DNFSB) staff members questioned the margin of safety associated with a postulated tri-n-butyl phosphate (TBP)/nitric acid runaway reaction due to the inadvertent heating of a canyon tank containing greater than 3000 lbs (1362 kg) of TBP. The margin of safety was partially based on experiments and calculations performed by the Actinide Technology Section (ATS) to support deletion of indication of tank agitation as a Safety Class System. In the technical basis for deletion of this system, ATS personnel conservatively calculated the equilibrium temperature distribution of a canyon tank containing TBP and nitric acid layers which were inadvertently heated by a steam jet left on following a transfer. The maximum calculated temperature (128 degrees C) was compared to the minimum initiation temperature for a runaway reaction (greater than 130 degrees C) documented by experimental work in the mid 195 0s. In this work, the initiation temperature as a function of nitric acid concentration was measured for 0 and 20 wt percent dissolved solids. The DNFSB staff members were concerned that data for 0 wt percent dissolved solids were not conservative given the facts that data for 20 wt percent dissolved solids show initiation temperatures at or below 130 degrees C and H-Canyon solutions normally contained a small amount of dissolved solids.

Thorium ions transport across Tri-n-butyl phosphate-benzene based supported liquid membranes  

SciTech Connect (OSTI)

Transport of Th(IV) ions across tri-n-butyl phosphate (TBP) benzene based liquid membranes supported in microporous hydrophobic polypropylene film (MHPF) has been studied. Various parameters such as variation of nitric acid concentration in the feed, TBP concentration in the membrane, and temperature on the given metal ions transport have been investigated. The effects of nitric acid and TBP concentrations on the distribution coefficient were also studied, and the data obtained were used to determine the Th ions-TBP complex diffusion coefficient in the membrane. Permeability coefficients of Th(IV) ions were also determined as a function of the TBP and nitric acid concentrations. The optimal conditions for the transport of Th(IV) ions across the membrane are 6 mol{sm_bullet}dm{sup -3} HNO{sub 3} concentration, 2.188 mol {center_dot} dm{sup -3} TBP concentration, and 25{degrees}C. The stoichiometry of the chemical species involved in chemical reaction during the transport of Th(IV) ions has also been studied.

Third international symposium on alcohol fuels technology  

SciTech Connect (OSTI)

At the opening of the Symposium, Dr. Sharrah, Senior Vice President of Continental Oil Company, addressed the attendees, and his remarks are included in this volume. The Symposium was concluded by workshops which addressed specific topics. The topical titles are as follows: alcohol uses; production; environment and safety; and socio-economic. The workshops reflected a growing confidence among the attendees that the alcohols from coal, remote natural gas and biomass do offer alternatives to petroleum fuels. Further, they may, in the long run, prove to be equal or superior to the petroleum fuels when the aspects of performance, environment, health and safety are combined with the renewable aspect of the biomass derived alcohols. Although considerable activity in the production and use of alcohols is now appearing in many parts of the world, the absence of strong, broad scale assessment and support for these fuels by the United States Federal Government was a noted point of concern by the attendees. The environmental consequence of using alcohols continues to be more benign in general than the petroleum based fuels. The exception is the family of aldehydes. Although the aldehydes are easily suppressed by catalysts, it is important to understand their production in the combustion process. Progress is being made in this regard. Of course, the goal is to burn the alcohols so cleanly that catalytic equipment can be eliminated. Separate abstracts are prepared for the Energy Data Base for individual presentations.

Extended performance of alcohol fumigation in diesel engines through different multipoint alcohol injection timing cycles  

SciTech Connect (OSTI)

This paper reports on the results of using multipoint port injection alcohol fumigation of a four-cycle turbocharged diesel engine in which the fumigation injection cycle was varied. The three cycles, dual with one-half of the alcohol injection on each engine revolution, single with all of the alcohol injection during the open intake valve revolution, and single with all of the alcohol injected during the closed intake valve revolution, lead to significant differences in the engines pressure-volume history and alcohol energy replacement tolerance. The engine was fumigated with both industrial grade ethanol and methanol and complete performance and emissions data (excluding aldehydes) were measured at low, medium, and high values of BMEP and rpm.

Play analysis and stratigraphic position of Uinta Basin tertiary - age oil and gas fields  

SciTech Connect (OSTI)

Tertiary-age sediments in the Uinta basin produce hydrocarbons from five types of plays. These play types were determined by hydrocarbon type, formation, depositional environment, rock type, porosity, permeability, source, and per-well recovery. Each well was reviewed to determine the stratigraphic position and producing characteristics of each producing interval. The five types of plays are as follows: (1) naturally fractured oil reservoirs, (2) low-permeability oil reservoirs, (3) high-permeability of oil reservoirs, (4) low-permeability gas reservoirs, and (5) tight gas sands. Several fields produce from multiple plays, which made it necessary to segregate the hydrocarbon production into several plays. The stratigraphic position of the main producing intervals is shown on a basin-wide cross section, which is color-coded by play type. This 61-well cross section has several wells from each significant Tertiary oil and gas field in the Uinta basin.

Has the National Health Insurance improved the inequality in the use of tertiary-care hospitals in Korea?  

Science Journals Connector (OSTI)

AbstractBackground To improve financial protection against catastrophic illness, the Korean government expanded the benefit coverage of the National Health Insurance (NHI) for cancer patients in 2005. This paper examined whether the policy has reduced income-inequality in the use of tertiary care hospitals. Methods We evaluated the effect of the policy on income-inequalities in outpatient visits and inpatient admissions to tertiary care hospitals, based on triple difference estimators. Using nationwide claims data of the NHI from 2002 to 2010, we compared cancer patients as a treatment group with liver disease and cardio-cerebrovascular disease as control groups and the lower-income with the highest-income group. Results Before the introduction of the policy, lower-income cancer patients utilized less inpatient and outpatient services in tertiary care hospitals than high-income patients did. After the benefit coverage was expanded, while the incidence and total number of inpatient admissions to tertiary care hospitals increased among cancer patients compared with liver diseases, lower-income cancer patients experienced a greater increase than those of higher-income did compared with both diseases. The use of outpatient services increased more in cancer patients than those of both diseases; however, the gap between the highest- and the lowest-income rarely decreased, except the incidence of visits when compared to liver disease. Conclusion Our findings indicated that the expanded NHI benefits coverage partially improved income-related inequalities in inpatient admissions to tertiary-care hospital, but not in outpatient visits.

Hispanics, Blacks and Whites driving under the influence of alcohol: results from the 1995 National Alcohol Survey  

Science Journals Connector (OSTI)

Objective: To report nationwide survey data on patterns of driving under the influence of alcohol among Whites, Blacks and Hispanics. Method: Data were obtained from a probability sample consisting of 1582 Blacks, 1585 Hispanics and 1636 Whites in the US household population. Interviews averaging 1 h in length were conducted in respondents’ homes by trained interviewers. Results: Self-reported rates of driving a car after having drunk enough ‘to be in trouble if stopped by the police’ were highest among White and Hispanic men (22 and 21%, respectively), as were lifetime arrest rates for driving under the influence of alcohol (13% for White men, 19% for Hispanic men). Additionally, our analyses suggest that drinkers who drive under the influence of alcohol are more likely to be men (regardless of ethnicity), consume more alcohol, and be alcohol dependent than drinkers who do not engage in alcohol-impaired driving.

Liver proteomics in progressive alcoholic steatosis  

SciTech Connect (OSTI)

Fatty liver is an early stage of alcoholic and nonalcoholic liver disease (ALD and NALD) that progresses to steatohepatitis and other irreversible conditions. In this study, we identified proteins that were differentially expressed in the livers of rats fed 5% ethanol in a Lieber–DeCarli diet daily for 1 and 3 months by discovery proteomics (two-dimensional gel electrophoresis and mass spectrometry) and non-parametric modeling (Multivariate Adaptive Regression Splines). Hepatic fatty infiltration was significantly higher in ethanol-fed animals as compared to controls, and more pronounced at 3 months of ethanol feeding. Discovery proteomics identified changes in the expression of proteins involved in alcohol, lipid, and amino acid metabolism after ethanol feeding. At 1 and 3 months, 12 and 15 different proteins were differentially expressed. Of the identified proteins, down regulation of alcohol dehydrogenase (? 1.6) at 1 month and up regulation of aldehyde dehydrogenase (2.1) at 3 months could be a protective/adaptive mechanism against ethanol toxicity. In addition, betaine-homocysteine S-methyltransferase 2 a protein responsible for methionine metabolism and previously implicated in fatty liver development was significantly up regulated (1.4) at ethanol-induced fatty liver stage (1 month) while peroxiredoxin-1 was down regulated (? 1.5) at late fatty liver stage (3 months). Nonparametric analysis of the protein spots yielded fewer proteins and narrowed the list of possible markers and identified D-dopachrome tautomerase (? 1.7, at 3 months) as a possible marker for ethanol-induced early steatohepatitis. The observed differential regulation of proteins have potential to serve as biomarker signature for the detection of steatosis and its progression to steatohepatitis once validated in plasma/serum. -- Graphical abstract: The figure shows the Hierarchial cluster analysis of differentially expressed protein spots obtained after ethanol feeding for 1 (1–3) and 3 (4–6) months. C and E represent pair-fed control and ethanol-fed rats, respectively. Highlights: ? Proteins related to ethanol-induced steatosis and mild steatohepatitis are identified. ? ADH1C and ALDH2 involved in alcohol metabolism are differentially expressed at 1 and 3 months. ? Discovery proteomics identified a group of proteins to serve as potential biomarkers. ? Using nonparametric analysis DDT is identified as a possible marker for liver damage.

Densities and isobaric vapor-liquid equilibria of butyl esters (methanoate to butanoate) with ethanol at 101.32 kPa  

SciTech Connect (OSTI)

Vapor-liquid equilibrium and densities at 101.32 kPa have been determined for the binary systems formed by four butyl esters (from methanoate to butanoate) with ethanol. The four systems exhibit positive deviations from ideal behavior, and all data (p-T-x-y) were found to be thermodynamically consistent. The activity coefficients and the dimensionless function G{sup E}/RT of the solution were correlated with its concentration by different equations. Am azeotrope was found in the mixture butyl methanoate (1) + ethanol (2) at T = 350.9 K and x{sub 1} = y{sub 1} = 0.088. The group contribution models ASOG and modified UNIFAC gave fair predictions.

Use of ferric sulfate: acid media for the desulfurization of model compounds of coal. [Dibenzothiophene, diphenyl sulfide, di-n-butyl sulfide  

SciTech Connect (OSTI)

The objective of this work has been to investigate the ability of ferric sulfate-acid leach systems to oxidize the sulfur in model compounds of coal. Ferric iron-acid leach systems have been shown to be quite effective at removal of inorganic sulfur in coal. In this study, the oxidative effect of ferric iron in acid-leach systems was studied using dibenzothiophene, diphenyl sulfide, and di-n-butyl sulfide as models of organic sulfur groups in coal. Nitrogen and oxygen, as well as various transition metal catalysts and oxidants, were utilized in this investigation. Dibenzothiophene was found to be quite refractory to oxidation, except in the case where metavanadate was added, where it appears that 40% oxidation to sulfone could have occurred per hour at 150/sup 0/C and mild oxygen pressure. Diphenyl sulfide was selectively oxidized to sulfoxide and sulfone in an iron and oxygen system. Approximately 15% conversion to sulfone occurred per hour under these conditions. Some of the di-n-butyl sulfide was cracked to 1-butene and 1-butanethiol under similar conditions. Zinc chloride and ferric iron were used at 200/sup 0/C in an attempt to desulfonate dibenzothiophene sulfone, diphenyl sulfone, and di-n-butyl sulfone. Di-n-butyl sulfone was completely desulfurized on one hour and fragmented to oxidized parafins, while dibenzothiophene sulfone and diphenyl sulfone were unaffected. These results suggest that an iron-acid leach process could only selectively oxidize aryl sulfides under mild conditions, representing only 20% of the organic sulfur in coal (8% of the total sulfur). Removal through desulfonation once selective sulfur oxidation had occurred was only demonstrated for alkyl sulfones, with severe oxidation of the fragmented paraffins also occurring in one hour.

Tectonostratigraphic reconstruction and lithofacies distribution of tertiary slope sedimentary rocks in the Western Mississippi Canyon area  

SciTech Connect (OSTI)

The distribution of upper Tertiary, sandstone-prone, deep-water sedimentary rocks from the vicinity of Cognac field, Mississippi Canyon (MC) 194, south of Mars field (MC763) is presented based on an integrated sequence stratigraphic analysis of seismic, well log, and biostratigraphic data. Paleo-salt distributions were reconstructed by plotting the changing positions of depocenters on five isopach maps generated from six key sequence boundaries. Depositional trends, projected under allochthonous salt sheets, indicated subsalt prospectivity. Sixteen sequences were interpreted and subdivided into three lowstand depositional units (basin-floor fan, slope fan, and prograding wedge). Thirty isochron/seismic facies maps were made to reveal the stratigraphic pattern through the late Tertiary. During the early Miocene, a salt-rimmed syncline centered north of Mars field in MC455 accumulated sediments. The salt rim collapsed, creating a middle Miocene turtle structure. Middle-late Miocene sand-rich turbidites bypassed this structure and were deposited to the south around Mars field and beyond. At the same time, another depotrough 30 mi east of Mars field channeled deep-water sands to the MC730 area. A late Miocene-early Pliocene counterregional fault striking parallel to the shelf edge formed as salt evacuated the area on the south side of the Cognac (MC194) and Lena (MC280) fields. This fault trapped the Pliocene reservoir sandstones that produce in these fields. Sedimentation during the late Pliocene-early Pleistocene was very slow (0.2m/1,000 yr) and characterized by thin, stacked, condensed sections of hemipelagic shale. Since the mid-Pleistocene, the Mississippi River has supplied sediments to the Mississippi Canyon area that have induced salt deformation that has in turn affected recent sedimentation.

Alcohol effects on navigational ability using ship handling simulator  

Science Journals Connector (OSTI)

In this paper, to examine the drinking status of officers on board multiple choice questionnaires were circularized under instruction and surveyed for 118 officers. Also, with a ship handling simulator, the effect of alcohol on maritime navigational performance is studied for the three blood alcohol concentrations (BACs) levels (0.0%, 0.05% and 0.08%). The eight participants were volunteer deck officer cadets in their senior year, at least 22 years of age, with previous experience on a bridge simulator. Additional experiments were done on maritime pilots. For baseline and performance trials, participants were randomized to one of four bridge simulator scenarios according to the current and the direction of the wind. In order to study the effects of alcohol on maritime navigational ability, (1) bio-signals using electrocardiogram (ECG), (2) performance using a simulator, and (3) mental workload using NASA-TLX were measured. As a result, this study found that alcohol intake significantly impairs the physical and mental ability of the ship operator. In particular, alcohol intake was found to have a direct correlation with changes in bio-signals such as heart rate not to mention simulator performance. In addition, alcohol intake increased mental workload according to the subjective mental workload evaluation undertaken by the test subject. The result of the analysis in this study includes the limited quantitative measure of the effects of alcohol, which is a major cause of operator fatigue. Relevance to Industry The alcohol effects on navigational ability and the frequency of drunken navigation are one of important interests in the maritime industry.

Solvent Extraction Behavior of Neptunium (IV) Ions between Nitric Acid and Diluted 30% Tri-butyl Phosphate in the Presence of Simple Hydroxamic Acids  

SciTech Connect (OSTI)

Formo- and aceto-hydroxamic acids are very effective reagents for stripping tetravalent actinide ions such as Np(IV) and Pu(IV) ions from a tri-butyl phosphate phase into nitric acid. Distribution data for Np(IV) in the presence of these hydroxamate ions have now been accumulated and trends established. Stability constants for aceto-hydroxamate complexes of Np(IV) and Np(V) ions have also been determined in a perchlorate medium, and these reaffirm the affinity of hydroxamate ligands for actinide (IV) ions over actinyl (V,VI) ions.

A New Flow Control Technique Using Diluted Epinephrine in the N-butyl-2-cyanoacrylate Embolization of Visceral Artery Pseudoaneurysms Secondary to Chronic Pancreatitis  

SciTech Connect (OSTI)

Although n-butyl-2-cyanoacrylate (NBCA) has been used as an effective liquid embolization material, its indication for pseudoaneurysms has seemingly been limited because of the technical difficulties of using NBCA, such as reflux to the parent artery and causing significant infarction. Thus, considerable skill in using NBCA or a device to control blood flow during its polymerization is required to achieve embolization without severe complications. We report our new technique for controlling blood flow using diluted epinephrine in transcatheter arterial NBCA embolization of five pseudoaneurysms in four cases secondary to hemosuccus pancreaticus.

Average Conformations Determined from PRE Data Provide High-Resolution Maps of Transient Tertiary Interactions in Disordered Proteins  

Science Journals Connector (OSTI)

In the last decade it has become evident that disordered states of proteins play important physiological and pathological roles and that the transient tertiary interactions often present in these systems can play a role in their biological activity. The structural characterization of such states has so far largely relied on ensemble representations, which in principle account for both their local and global structural features. However, these approaches are inherently of low resolution due to the large number of degrees of freedom of conformational ensembles and to the sparse nature of the experimental data used to determine them. Here, we overcome these limitations by showing that tertiary interactions in disordered states can be mapped at high resolution by fitting paramagnetic relaxation enhancement data to a small number of conformations, which can be as low as one. This result opens up the possibility of determining the topology of cooperatively collapsed and hidden folded states when these are present in the vast conformational landscape accessible to disordered states of proteins. As a first application, we study the long-range tertiary interactions of acid-unfolded apomyoglobin from experimentally measured paramagnetic relaxation enhancement data.

Seismic reflection evidence for two phase development of Tertiary basins from east-central Nevada  

SciTech Connect (OSTI)

Two east-west seismic reflection profiles crossing Antelope Valley, Smokey Valley, Railroad Valley and Big Sand Springs Valley demonstrate the evolution of Tertiary extension from broad sags to narrow, fault-bounded basins. Seismic reflection data was acquired for the Anschutz Corporation by the Digicon Corporation during the winter of 1988/1989. Reprocessing of a 480 channel, 60 fold, dynamite source experiment enabled good imaging of the basin stratigraphy. These data suggest two distinct phases of basin development occurred, separated by a regional unconformity. The early phase is characterized by development of a broad basin riddled with many small offset normal faults. The later phase shows a narrowing of the basin and subsidence along one dominant structure, an apparent planar normal fault. The unconformity separating the two phases of extension marks a transition from broad subsidence to local asymmetric tilting that took place over a short period of time relative to sedimentation rates. Antelope Valley and Railroad Valley clearly show strong evidence for two phase development, whereas Smokey Valley represents mostly the early phase and Big Sand Springs Valley represents only the later phase of extension. The absence of dating within the basins precludes the authors from determining if the abrupt tectonic transition within the basins resulted from differences in local strain rates or amounts, or was due to changes in regional stress fields.

Maturation of Tertiary sediments in the Asian Continental Margins: A basis for hydrocarbon generation studies  

SciTech Connect (OSTI)

In the marginal areas of the Asian continent, the Paleogene and Miocene coal-bearing formations are sporadically distributed. In some areas, particularly in the sea regions, their equivalents are possibly explored for oil and gas. The basins mainly formed as tectonic depressions, and are filled with fluvial to marine clastic rocks. The formations show marked lateral variation in thickness, lithology, and sediment characteristics, which are related to the geotectonic settings of the basins at active plate margins. Remarkable accumulation of overburden and high paleogeothermal conditions, which are marked in northern Kyushu, Japan, and Thailand, influenced diagenesis. Organic and inorganic maturation studies in northern Kyushu reveal a progress of diagenesis from the inland of Kyushu toward the sea region essentially controlled by additional heat supply from the sea region during and after sedimentation. The sediments on the land surface are chiefly overmatured, and/or contain minor amounts of organic carbon. High paleogeothermal influence on Tertiary maturation is clear also in northern Thailand. The high paleotemperature conditions in these areas may be related to tectonic interaction between the oceanic and continental plates.

Factors controlling reservoir quality in tertiary sandstones and their significance to geopressured geothermal production  

SciTech Connect (OSTI)

Variable intensity of diagenesis is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the upper and lower Texas coast. Detailed comparison of Frio sandstone from the Chocolate Bayou/Danbury Dome area, Brazoria County, and Vicksburg sandstones from the McAllen Ranch Field area, Hidalgo County, reveals that extent of diagenetic modification is most strongly influenced by (1) detrital mineralogy and (2) regional geothermal gradients. The regional reservoir quality of Frio sandstones from Brazoria County is far better than that characterizing Vicksburg sandstones from Hidalgo County, especially at depths suitable for geopressured geothermal energy production. However, in predicting reservoir quality on a site-specific basis, locally variable factors such as relative proportions for porosity types, pore geometry as related to permeability, and local depositional environment must also be considered. Even in an area of regionally favorable reservoir quality, such local factors can significantly affect reservoir quality and, hence, the geothermal production potential of a specific sandstone unit.

Interplay between Secondary and Tertiary Structure Formation in Protein Folding Cooperativity  

E-Print Network [OSTI]

Protein folding cooperativity is defined by the nature of the finite-size thermodynamic transition exhibited upon folding: two-state transitions show a free energy barrier between the folded and unfolded ensembles, while downhill folding is barrierless. A microcanonical analysis, where the energy is the natural variable, has shown better suited to unambiguously characterize the nature of the transition compared to its canonical counterpart. Replica exchange molecular dynamics simulations of a high resolution coarse-grained model allow for the accurate evaluation of the density of states, in order to extract precise thermodynamic information, and measure its impact on structural features. The method is applied to three helical peptides: a short helix shows sharp features of a two-state folder, while a longer helix and a three-helix bundle exhibit downhill and two-state transitions, respectively. Extending the results of lattice simulations and theoretical models, we find that it is the interplay between secondary structure and the loss of non-native tertiary contacts which determines the nature of the transition.

THE TRENDS HIGH-CONTRAST IMAGING SURVEY. II. DIRECT DETECTION OF THE HD 8375 TERTIARY  

SciTech Connect (OSTI)

We present the direct imaging detection of a faint tertiary companion to the single-lined spectroscopic binary HD 8375 AB. Initially noticed as an 53 m s{sup -1} yr{sup -1} Doppler acceleration by Bowler et al., we have obtained high-contrast adaptive optics observations at Keck using NIRC2 that spatially resolve HD 8375 C from its host(s). Astrometric measurements demonstrate that the companion shares a common proper-motion. We detect orbital motion in a clockwise direction. Multiband relative photometry measurements are consistent with an early M-dwarf spectral type ({approx}M1V). Our combined Doppler and imaging observations place a lower-limit of m {>=} 0.297 M{sub Sun} on its dynamical mass. We also provide a refined orbit for the inner pair using recent radial velocity measurements obtained with the High Resolution Echelle Spectrometer. HD 8375 is one of many triple-star systems that are apparently missing in the solar neighborhood.

Geothermal source potential and utilization for alcohol production  

SciTech Connect (OSTI)

A study was conducted to assess the technical and economic feasibility of using a potential geothermal source to drive a fuel grade alcohol plant. Test data from the well at the site indicated that the water temperature at approximately 8500 feet should approach 275/sup 0/F. However, no flow data was available, and so the volume of hot water that can be expected from a well at this site is unknown. Using the available data, numerous fuel alcohol production processes and various heat utilization schemes were investigated to determine the most cost effective system for using the geothermal resource. The study found the direct application of hot water for alcohol production based on atmospheric processes using low pressure steam to be most cost effective. The geothermal flow rates were determined for various sizes of alcohol production facility using 275/sup 0/F water, 235/sup 0/F maximum processing temperature, 31,000 and 53,000 Btu per gallon energy requirements, and appropriate process approach temperatures. It was determined that a 3 million gpy alcohol plant is the largest facility that can practically be powered by the flow from one large geothermal well. An order-of-magnitude cost estimate was prepared, operating costs were calculated, the economic feasibility of the propsed project was examined, and a sensitivity analysis was performed.

Effect of varying polyacrylamide molecular weight on tertiary oil recovery from porous media of varying permeability  

SciTech Connect (OSTI)

Three different molecular weight emulsion polyacrylamides (PAA) have been tested for their ability to recover oil from a multi-permeability Berea core system. Injection of a 6.5 x 10/sup 6/, 17 x 10/sup 6/, and 36 x 10/sup 6/ molecular weight PAA resulted in oil recovery from the multiple permeability core systems of 53.4, 63.7, and 57.2 percent of the waterflood residual oil, respectively. In tests with 15 g/kg Na/sub 2/CO/sub 3/, injection of the polymer systems resulted in recoveries of 65.6, 75.3, and 68.0 percent of the waterflood residual oil, respectively. In the presence of alkali, the injection of high molecular weight PAA resulted in the reduction of fluid flow into the medium and low permeability cores with 70 to 75 percent of the tertiary oil being recovered from the high permeability core. Decreasing the PAA molecular weight to 17 x 10/sup 6/ and subsequently to 6.5 x 10/sup 6/ resulted in an increasing amount of fluid flowing through the low and medium permeability cores. While decreasing the molecular weight of the PAA resulted in increased fluid diversion, the 6.5 x 10/sup 6/ molecular weight PAA recovery efficiency was less than either of the other two polymers in the high permeability core. The data indicates selection of too large a polymer can result in less than maximum oil recovery from a heterogeneous permeability reservoir as a result of lower sweep efficiency. Selection of too small a polymer can result in less than maximum oil recovery from a heterogeneous permeability reservoir as a result of decreased oil recovery from the high permeability zones. Proper selection of polyacrylamide for a heterogeneous permeability reservoir either in the presence or in the absence of alkali will maximize oil recovery.

Alcohol consumption, Lewis phenotypes, and risk of ischemic heart disease  

SciTech Connect (OSTI)

The authors have previously found an increased risk of ischemic heart disease (IHD) in men with the Lewis phenotype Le(a[minus]b[minus]) and suggested that the Lewis blood group has a close genetic relation with insulin resistance. The authors have investigated whether any conventional risk factors explain the increased risk in Le(a[minus]b[minus]) men. 3,383 men aged 53-75 years were examined in 1985-86, and morbidity and mortality during the next 4 years were recorded. At baseline, the authors excluded 343 men with a history of myocardial infarction, angina pectoris, intermittent claudication, or stroke. The potential risk factors examined were alcohol consumption, physical activity, tobacco smoking, serum cotinine, serum lipids, body-mass index, blood pressure, prevalence of hypertension and non-insulin-dependent diabetes mellitus, and social class. In 280 (9.6%) men with Le(a[minus]b[minus]), alcohol was the only risk factor significantly associated with risk of IHD. There was a significant inverse dose-effect relation between alcohol consumption and risk; trend tests, with adjustment for age, were significant for fatal IHD (p=0.02), all IHD (p=0.03), and all causes of death (p=0.02). In 2649 (90.4%) men with other phenotypes, there was a limited negative association with alcohol consumption. In Le(a[minus]b[minus]) men, a group genetically at high risk of IHD, alcohol consumption seems to be especially protective. The authors suggest that alcohol consumption may modify insulin resistance in Le(a[minus]b[minus]) men.

Use of Treated Municipal Wastewater as Power Plant Cooling System Makeup Water: Tertiary Treatment versus Expanded Chemical Regimen for Recirculating Water Quality Management  

SciTech Connect (OSTI)

Treated municipal wastewater is a common, widely available alternative source of cooling water for thermoelectric power plants across the U.S. However, the biodegradable organic matter, ammonia-nitrogen, carbonate and phosphates in the treated wastewater pose challenges with respect to enhanced biofouling, corrosion, and scaling, respectively. The overall objective of this study was to evaluate the benefits and life cycle costs of implementing tertiary treatment of secondary treated municipal wastewater prior to use in recirculating cooling systems. The study comprised bench- and pilot-scale experimental studies with three different tertiary treated municipal wastewaters, and life cycle costing and environmental analyses of various tertiary treatment schemes. Sustainability factors and metrics for reuse of treated wastewater in power plant cooling systems were also evaluated. The three tertiary treated wastewaters studied were: secondary treated municipal wastewater subjected to acid addition for pH control (MWW_pH); secondary treated municipal wastewater subjected to nitrification and sand filtration (MWW_NF); and secondary treated municipal wastewater subjected nitrification, sand filtration, and GAC adsorption (MWW_NFG). Tertiary treatment was determined to be essential to achieve appropriate corrosion, scaling, and biofouling control for use of secondary treated municipal wastewater in power plant cooling systems. The ability to control scaling, in particular, was found to be significantly enhanced with tertiary treated wastewater compared to secondary treated wastewater. MWW_pH treated water (adjustment to pH 7.8) was effective in reducing scale formation, but increased corrosion and the amount of biocide required to achieve appropriate biofouling control. Corrosion could be adequately controlled with tolytriazole addition (4-5 ppm TTA), however, which was the case for all of the tertiary treated waters. For MWW_NF treated water, the removal of ammonia by nitrification helped to reduce the corrosivity and biocide demand. Also, the lower pH and alkalinity resulting from nitrification reduced the scaling to an acceptable level, without the addition of anti-scalant chemicals. Additional GAC adsorption treatment, MWW_NFG, yielded no net benefit. Removal of organic matter resulted in pitting corrosion in copper and cupronickel alloys. Negligible improvement was observed in scaling control and biofouling control. For all of the tertiary treatments, biofouling control was achievable, and most effectively with pre-formed monochloramine (2-3 ppm) in comparison with NaOCl and ClO2. Life cycle cost (LCC) analyses were performed for the tertiary treatment systems studied experimentally and for several other treatment options. A public domain conceptual costing tool (LC3 model) was developed for this purpose. MWW_SF (lime softening and sand filtration) and MWW_NF were the most cost-effective treatment options among the tertiary treatment alternatives considered because of the higher effluent quality with moderate infrastructure costs and the relatively low doses of conditioning chemicals required. Life cycle inventory (LCI) analysis along with integration of external costs of emissions with direct costs was performed to evaluate relative emissions to the environment and external costs associated with construction and operation of tertiary treatment alternatives. Integrated LCI and LCC analysis indicated that three-tiered treatment alternatives such as MWW_NSF and MWW_NFG, with regular chemical addition for treatment and conditioning and/or regeneration, tend to increase the impact costs and in turn the overall costs of tertiary treatment. River water supply and MWW_F alternatives with a single step of tertiary treatment were associated with lower impact costs, but the contribution of impact costs to overall annual costs was higher than all other treatment alternatives. MWW_NF and MWW_SF alternatives exhibited moderate external impact costs with moderate infrastructure and chemical conditioner dosing, which makes them (especially

Modeling of the simultaneous extraction of nitric acid and uranyl nitrate with tri-n-butyl phosphate. Application to extraction operation  

SciTech Connect (OSTI)

A mathematical model developed for the equilibrium HNO{sub 3}-UO{sub 2}(NO{sub 3}){sub 2}-tri-n-butyl phosphate (TBP)-diluent is the basis of the computation of distribution isotherms. The isotherms are used to study the influence of TBP concentration on two chosen operation parameters, distribution coefficients and number of theoretical stages, for the selected flow sheets. It is established that an increase in TBP concentration leads to a decrease in the number of theoretical stages for the extraction flow sheets but to their increase for the striping flow sheets. Given diagrams can be used to determine the efficiency of extraction processes. Agreement with available literature calculations on the number of theoretical stages supports the use of the model in the computation of distribution isotherms, of the system quoted above, in a wide range of nitric acid, uranyl nitrate, and TBP concentrations.

Production of Mixed Alcohols from Bio-syngas over Mo-based Catalyst  

Science Journals Connector (OSTI)

A series of Mo-based catalysts prepared by sol-gel method using citric acid as complexant were successfully applied in the high efficient production of mixed alcohols from bio-syngas derived from the biomass gasification. The Cu1Co1Fe1Mo1Zn0.5? 6%K catalyst exhibited a higher activity on the space-time yield of mixed alcohols compared with the other Mo-based catalysts. The carbon conversion significantly increases with rising temperature below 340 °C but the alcohol selectivity has an opposite trend. The maximum mixed alcohols yield derived from biomass gasification is 494.8 g/(kgcatal·h) with the C2+ (C2—C6 higher alcohols) alcohols of 80.4% under the tested conditions. The alcohol distributions are consistent with the Schulz-Flory plots except methanol. In the alcohols products the C2+ alcohols (higher alcohols) dominate with a weight ratio of 70%–85%. The Mo-based catalysts have been characterized by X-ray diffraction and N2 adsorption/desorption. The clean bio-fules of mixed alcohols derived from bio-syngas with higher octane values could be used as transportation fuels or petrol additives.

Pacific Northwest National Laboratory (PNNL) and National Renewable Energy Laboratory (NREL) are researching the feasibility of producing mixed alcohols from biomass-derived synthesis gas (syngas). PNNL is obtaining commercially available mixed alcohol or preparing promising mixed-alcohol catalysts and screening them in a laboratory-scale reactor system. The most promising catalysts are provided to NREL for testing using a slipstream from a pilot-scale biomass gasifier. After a review of the literature in 2006 and conversations with companies that produce catalysts, it was determined that no commercial mixed-alcohol synthesis catalysts were available. One manufacturer supplied a modified methanol catalyst that was tested in the PNNL laboratory-scale system and provided to NREL for further testing. PNNL also prepared and tested the behavior of 10 other catalysts representing the distinct catalyst classes for mixed alcohol syntheses. Based on those results,testing in 2007 focused on the performance of the rhodium-based catalysts. The effects of adding promoters to the rhodium catalysts in addition to the manganese already being used were examined. The iron and rhenium promoters both stood out as achieving higher carbon selectivities , followed by Cu. Iridium and Li, on the other hand, had low carbon selectivity ratios of 0.27 and 0.22, respectively. Although testing of candidate promoters is not complete, it appears that Ir and Li promoters warrant further optimization and possibly combination to further improve STYs and carbon selectivities to C2+ oxygenates. However, using these promoters, it will be necessary to incorporate a separate hydrogenation catalyst to improve the yield of C2+ alcohols with respect to the other oxygenates. Fe, Re, and Cu stand out as possible candidates in this respect, but additional research is needed to examine whether they can be combined with the other promoters on the Rh-based catalyst or need to be optimized on a separate catalyst support that is either physically mixed or used in series with the promoted Rh-based catalyst.

Fumigation of alcohol in a light duty automotive diesel engine  

SciTech Connect (OSTI)

A light-duty automotive diesel engine was fumigated with methanol and ethanol in amounts up to 35% and 50% of the total fuel energy respectively. The main purpose of this study was to determine the effect of alcohol (methanol and ethanol) fumigation on engine performance at various operating conditions. Engine fuel efficiency, emissions, smoke, and the occurrence of severe knock were the parameters used to evaluate performance. Raw exhaust particulate and its soluble organic extract were screened for biological activity using the Ames Salmonella typhimurium assay. Results are given for a test matrix made up of twelve steady-state operating conditions. For all conditions except the 1/4 rack (light load) condition, modest thermal efficiency gains were noted upon ethanol fumigation. Methanol showed the same increase at 3/4 and full rack (high load) conditions. However, engine roughness or the occurrence of severe knock limited the maximum amount of alcohol that could be fumigated. Brake specific NO/sub x/ concentrations were found to decrease for all ethanol conditions tested. Oxides of nitrogen emissions, on a volume basis, decreased for all alcohol conditions tested. Based on the limited particulate data analyzed, it appears as though ethanol fumigation, like methanol fumigation, while lowering the mass of particulate emitted, does enhance the biological activity of that particulate.

High energy beam impact tests on a LHC tertiary collimator at the CERN high-radiation to materials facility  

Science Journals Connector (OSTI)

The correct functioning of a collimation system is crucial to safely operate highly energetic particle accelerators, such as the Large Hadron Collider (LHC). The requirements to handle high intensity beams can be demanding. In this respect, investigating the consequences of LHC particle beams hitting tertiary collimators (TCTs) in the experimental regions is a fundamental issue for machine protection. An experimental test was designed to investigate the robustness and effects of beam accidents on a fully assembled collimator, based on accident scenarios in the LHC. This experiment, carried out at the CERN High-Radiation to Materials (HiRadMat) facility, involved 440 GeV proton beam impacts of different intensities on the jaws of a horizontal TCT. This paper presents the experimental setup and the preliminary results obtained, together with some first outcomes from visual inspection and a comparison of such results with numerical simulations.

Review and reconnaissance of the hydrogeology of Tertiary sedimentary rocks in the vicinity of Frenchman Flat, Nevada Test Site  

SciTech Connect (OSTI)

Work is currently underway within the Underground Test Area (UGTA) subproject of the US Department of Energy/Nevada Operations Office Environmental Restoration Program to develop corrective action plans in support of the overall corrective action strategy for the Nevada Test Site (NTS) as established in the Federal Facility Agreement and Consent Order (FFACO, 1996). A closure plan is currently being developed for Frenchman Flat, which has been identified in the FFACO as a Corrective Action Unit (CAU). Part of this effort requires that hydrogeologic data be compiled for inclusion in a CAU-specific hydrologic flow and transport model that will be used to predict contaminant boundaries. Hydrogeologic maps and cross sections are currently being prepared for use in the model to define the nature and extent of aquifers and confining units that might influence the flow of contaminated groundwater from underground nuclear tests conducted in Frenchman Flat. During this effort, it has been found that older Tertiary-age sediments might be hydrogeologically important in the Frenchman Flat model area. Although the character and extent of these units are poorly known, there is reason to believe that in some parts of Frenchman Flat they may lie between the regional Lower Carbonate Aquifer (LCA) and the younger Tertiary saturated alluvium and volcanic units in which several underground nuclear tests were conducted. It was not possible to quickly determine their extent, or ascertain whether or not these units might act as confining units or aquifers. The work described in this report was done to gain a better understanding of the hydrogeology of these rocks.

Contrasting styles of Pre-Cenozoic and mid-Tertiary crustal evolution in northern Mexico: Evidence from deep crustal xenoliths from La Olivina  

SciTech Connect (OSTI)

The principal deep crustal rock types found at the La Olivina xenolith locality in southeastern Chihuahua, Mexico, are mafic granulites, paragneisses, and intermediate- to silicic-composition orthogneisses. These granulite facies xenoliths are interpreted in terms of two age groups, pre-Cenozoic and mid-Tertiary, based on previous ion probe dating of zircons from the xenoliths and on isotopic comparisons of the xenoliths to rocks of known age. The mafic granulites have Pb, Nd, and Sr isotopic compositions identical to those of Oligocene volcanic rocks from the La Olivina region. Compositionally, they are olivine-normative gabbroic cumulates, and they precipitated from two or more mid-Tertiary basalt to dacite or rhyolite assimilation/fractional crystallization series. Mineral assemblages in the xenoliths record pressures of {le} 7.2 kbar or depths of < 25 km. If these are the maximum pressures the rocks experienced and if the crust was > 35 km thick in Oligocene time as inferred from regional tectonic considerations, then the mafic granulites cannot be samples of basaltic magmas underplated near the crust-mantle boundary. The cumulate protoliths for the mafic granulites probably formed in magma chambers well above the Moho. The mafic granulites are plausibly ignimbrite fields of Mexico. Pre-Cenozoic and mid-Tertiary crustal evolution followed very different paths in northern Mexico. For example, Nd isotopic evidence for crustal recycling is much more evident in rocks associated with the Paleozoic convergence than in rocks produced during mid-Tertiary magmatism. Furthermore, mafic rocks are very rare in the pre-Cenozoic xenolith suite, but they dominate the mid-Tertiary one. The rarity of pre-Cenozoic mafic xenoliths suggests that Proterozoic and Paleozoic lower crust may have delaminated in response to crustal overthickening associated with the Ouachita collision event. 97 refs., 14 figs., 5 tabs.

Electrolytic method to make alkali alcoholates using ion conducting alkali electrolyte/separator  

DOE Patents [OSTI]

Alkali alcoholates, also called alkali alkoxides, are produced from alkali metal salt solutions and alcohol using a three-compartment electrolytic cell. The electrolytic cell includes an anolyte compartment configured with an anode, a buffer compartment, and a catholyte compartment configured with a cathode. An alkali ion conducting solid electrolyte configured to selectively transport alkali ions is positioned between the anolyte compartment and the buffer compartment. An alkali ion permeable separator is positioned between the buffer compartment and the catholyte compartment. The catholyte solution may include an alkali alcoholate and alcohol. The anolyte solution may include at least one alkali salt. The buffer compartment solution may include a soluble alkali salt and an alkali alcoholate in alcohol.

Transport study of hafnium(IV) and zirconium(IV) ions mutual separation by using Tri-n-butyl phosphate-xylene-based supported liquid membranes  

SciTech Connect (OSTI)

A Hf transport study through supported liquid membranes has been carried out to determine flux and permeability data for this metal ion. Tri-n-butyl phosphate (TBP)-xylene-based liquid membranes supported in polypropylene hydrophobic microporous film have been used. These data for hafnium and the previous data for zirconium have furnished the Zr to Hf flux ratio (S) as a function of nitric acid and TBP concentrations of the order of 12 in a single stage at room temperature. Optimum conditions for the separation of these two metal ions appear to 5-6 TBP mol/dm{sup 3} HNO{sub 3}, concentrations {le} 2.93 mol/dm{sup 3}, and 10C. The value of S from an aqueous solution containing 2.4% Hf with respect to Zr has been found to be >125 at 10C and 1.78 mol/dm{sup 3} TBP concentration in the membrane. The technique appears to be feasible for purification of Zr respect to Hf or vice versa.

Low-temperature CVD of iron, cobalt, and nickel nitride thin films from bis[di(tert-butyl)amido]metal(II) precursors and ammonia  

SciTech Connect (OSTI)

Thin films of late transition metal nitrides (where the metal is iron, cobalt, or nickel) are grown by low-pressure metalorganic chemical vapor deposition from bis[di(tert-butyl)amido]metal(II) precursors and ammonia. These metal nitrides are known to have useful mechanical and magnetic properties, but there are few thin film growth techniques to produce them based on a single precursor family. The authors report the deposition of metal nitride thin films below 300?°C from three recently synthesized M[N(t-Bu){sub 2}]{sub 2} precursors, where M?=?Fe, Co, and Ni, with growth onset as low as room temperature. Metal-rich phases are obtained with constant nitrogen content from growth onset to 200?°C over a range of feedstock partial pressures. Carbon contamination in the films is minimal for iron and cobalt nitride, but similar to the nitrogen concentration for nickel nitride. X-ray photoelectron spectroscopy indicates that the incorporated nitrogen is present as metal nitride, even for films grown at the reaction onset temperature. Deposition rates of up to 18?nm/min are observed. The film morphologies, growth rates, and compositions are consistent with a gas-phase transamination reaction that produces precursor species with high sticking coefficients and low surface mobilities.

T4 DNA condensation in water-alcohol media  

E-Print Network [OSTI]

The process of compaction of high molecular weight DNA T4 is investigated directly in a AFM liquid cell. The AFM-images of globules formed by DNA molecules in the result of compaction in water-alcohol environments at high izopropanol concentration (80%) are received; it is found that at intermediate concentration of izopropanol (40-50%) the DNA molecules form partially compacted formations in which the separate coils of macromolecules twist in toroidal structures. It is shown using the technique of deconvolution of the AFM-images that the globule include only one closely packed DNA molecule. The model of DNA packing is proposed on the basis of AFM experiment.

Role of osteopontin in hepatic neutrophil infiltration during alcoholic steatohepatitis  

SciTech Connect (OSTI)

Alcoholic liver disease (ALD) is a major complication of heavy alcohol (EtOH) drinking and is characterized by three progressive stages of pathology: steatosis, steatohepatitis, and fibrosis/cirrhosis. Alcoholic steatosis (AS) is the initial stage of ALD and consists of fat accumulation in the liver accompanied by minimal liver injury. AS is known to render the hepatocytes increasingly sensitive to toxicants such as bacterial endotoxin (LPS). Alcoholic steatohepatitis (ASH), the second and rate-limiting step in the progression of ALD, is characterized by hepatic fat accumulation, neutrophil infiltration, and neutrophil-mediated parenchymal injury. However, the pathogenesis of ASH is poorly defined. It has been theorized that the pathogenesis of ASH involves interaction of increased circulating levels of LPS with hepatocytes being rendered highly sensitive to LPS due to heavy EtOH consumption. We hypothesize that osteopontin (OPN), a matricellular protein (MCP), plays an important role in the hepatic neutrophil recruitment due to its enhanced expression during the early phase of ALD (AS and ASH). To study the role of OPN in the pathogenesis of ASH, we induced AS in male Sprague-Dawley rats by feeding EtOH-containing Lieber-DeCarli liquid diet for 6 weeks. AS rats experienced extensive fat accumulation and minimal liver injury. Moderate induction in OPN was observed in AS group. ASH was induced by feeding male Sprague-Dawley rats EtOH-containing Lieber-DeCarli liquid diet for 6 weeks followed by LPS injection. The ASH rats had substantial neutrophil infiltration, coagulative oncotic necrosis, and developed higher liver injury. Significant increases in the hepatic and circulating levels of OPN was observed in the ASH rats. Higher levels of the active, thrombin-cleaved form of OPN in the liver in ASH group correlated remarkably with hepatic neutrophil infiltration. Finally, correlative studies between OPN and hepatic neutrophil infiltration was corroborated in a simple rat peritoneal model where enhanced peritoneal fluid neutrophil infiltration was noted in rats injected OPN intraperitoneally. Taken together these data indicate that OPN expression induced during ASH may play a significant role in the pathogenesis of ASH by stimulating neutrophil transmigration.

Solubility of carbon dioxide, nitrous oxide, ethane, and nitrogen in 1-butyl-1-methylpyrrolidinium and trihexyl(tetradecyl)phosphonium tris(pentafluoroethyl)trifluorophosphate (eFAP) ionic liquids  

Science Journals Connector (OSTI)

The density and viscosity of the ionic liquids 1-butyl-1-methylpyrrolidinium tris(pentafluoroethyl)trifluorophosphate [C1C4Pyrro][eFAP] and trihexyl(tetradecyl)phosphonium tris(pentafluoroethyl)trifluorophosphate [P66614][eFAP] were measured as a function of temperature and pressure and as a function of temperature, respectively. These two ionic liquids are more viscous than those based in the same anion associated to imidazolium cations. The effect of the addition of water on the density and viscosity of [P66614][eFAP] was studied at pressures close to atmospheric and as a function of the temperature. This ionic liquid is only partially miscible with water, its solubility being of around X H 2 O = 0.2 in the range of (303 to 315) K. Experimental values of the solubility of carbon dioxide, nitrous oxide, ethane, and nitrogen were obtained as a function of temperature and at pressures close to atmospheric. Carbon dioxide and nitrous oxide are the more soluble gases with mole fraction solubilities up to 7 · 10?2. Ethane is four times and 1.3 times less soluble than carbon dioxide in [C1C4Pyrro][eFAP] and [P66614][eFAP], respectively. Nitrogen is one order of magnitude less soluble than the others gases in the two ionic liquids studied. In order to understand behavior of the different gases with these ionic liquids, the thermodynamic functions of solvation such as enthalpy and entropy were calculated from the variation of the Henry’s law constant with temperature. It is shown that the more favorable interactions of the gases with the ionic liquid explain the larger solubility of carbon dioxide and nitrous oxide in [C1C4Pyrro][eFAP]. In the case of [P66614][eFAP], it is the less favorable entropic contribution that explains the lower solubility of ethane in this ionic liquid.

Biostratigraphic, chronostratigraphic, and stratigraphic sequence analysis of Lower Tertiary marine sediments of Alabama for indicators of sea-level change  

SciTech Connect (OSTI)

Early Eocene to late Oligocene marine sedimentary units in southwestern Alabama were sampled at closely spaced intervals to derive a precise time-stratigraphic framework and to determine the paleoecological and mineralogical responses to fluctuations in sea level. Paleontologic control consisted of planktonic, smaller and larger benthonic foraminifera, calcareous nannofossils, dinoflagellates, and megafossils. Paleomagnetic reversals were delineated in two boreholes which, when supplemented by strontium isotope dates and the biostratigraphic control, provided a robust in situ chronostratigraphy for the Gulf Coast lower Tertiary. Paleoecologic trends in regression and transgression can be clearly correlated across major regional facies changes. Using the chronostratigraphy developed here, the second-, third-, and fourth-orders of Vail's global sea-level cycles can be recognized and demonstrate the influence of sea-level change on sedimentation. Stratigraphic systems tracts (SSTs) and bounding surfaces in outcrop were determined by lithologic variations and paleoecologic trends, and additionally by gamma logs in the cores. The lower sequence boundary occurs at a contact where an older, relatively fine-grained, deep-water, fossiliferous unit was abruptly succeeded by a coarse-grained, shallow-water, poorly fossiliferous unit. The transgressive surface occurs at the base of a fining- and deepening-upwards unit that was commonly glauconitic and very fossiliferous. Transgression culminated with a pulse of planktonic microfossils in a bed having reduced clastic sedimentation; on the log the surface of maximum starvation was marked by a gamma spike.

Process for producing high purity isoolefins and dimers thereof by dissociation of ethers  

DOE Patents [OSTI]

Alkyl tertiary butyl ether or alkyl tertiary amyl ether is dissociated by vapor phase contact with a cation acidic exchange resin at temperatures in the range of 150 to 250 F at LHSV of 0.1 to 20 to produce a stream consisting of unreacted ether, isobutene or isoamylene and an alcohol corresponding to the alkyl radical. After the alcohol is removed, the ether/isoolefin stream may be fractionated to obtain a high purity isoolefin (99+%) or the ether/isoolefin stream can be contacted in liquid phase with a cation acidic exchange resin to selectively dimerize the isoolefin in a highly exothermic reaction, followed by fractionation of the dimerization product to produce high purity diisoolefin (97+%). In the case where the alkyl is C[sub 3] to C[sub 6] and the corresponding alcohol is produced on dissociation of the ether, combined dissociation-distillation may be carried out such that isoolefin is the overhead product and alcohol the bottom. 2 figs.

Biofouling of reverse-osmosis membranes under different shear rates during tertiary wastewater desalination: Microbial community composition  

Science Journals Connector (OSTI)

Abstract We investigated the influence of feed-water shear rate during reverse-osmosis (RO) desalination on biofouling with respect to microbial community composition developed on the membrane surface. The RO membrane biofilm's microbial community profile was elucidated during desalination of tertiary wastewater effluent in a flat-sheet lab-scale system operated under high (555.6 s?1), medium (370.4 s?1), or low (185.2 s?1) shear rates, corresponding to average velocities of 27.8, 18.5, and 9.3 cm s?1, respectively. Bacterial diversity was highest when medium shear was applied (Shannon–Weaver diversity index H' = 4.30 ± 0.04) compared to RO-membrane biofilm developed under lower and higher shear rates (H? = 3.80 ± 0.26 and H? = 3.42 ± 0.38, respectively). At the medium shear rate, RO-membrane biofilms were dominated by Betaproteobacteria, whereas under lower and higher shear rates, the biofilms were dominated by Alpha- and Gamma- Proteobacteria, and the latter biofilms also contained Deltaproteobacteria. Bacterial abundance on the RO membrane was higher at low and medium shear rates compared to the high shear rate: 8.97 × 108 ± 1.03 × 103, 4.70 × 108 ± 1.70 × 103 and 5.72 × 106 ± 2.09 × 103 copy number per cm2, respectively. Interestingly, at the high shear rate, the RO-membrane biofilm's bacterial community consisted mainly of populations known to excrete high amounts of extracellular polymeric substances. Our results suggest that the RO-membrane biofilm's community composition, structure and abundance differ in accordance with applied shear rate. These results shed new light on the biofouling phenomenon and are important for further development of antibiofouling strategies for RO membranes.

Alcohol flushing for enhanced removal of coal tar from contaminated soils  

SciTech Connect (OSTI)

Alcohol flushing for enhancing the removal of coal tar from contaminated soils and reducing coal tar concentrations in the aqueous-phase leachate was investigated. Four soil columns were packed with relatively undisturbed coal tar contaminated soils collected from a former coal gasification site. These columns were leached with water and then flushed with isopropyl alcohol (IPA) solutions. Initially, total coal tar concentrations in water leachate ranged from = 0.1 to 150 mg/L for the four columns. Coal tar concentrations in the column effluent generally increased three to five orders of magnitude during the initial IPA flush. Each column was flushed with 1-3 pore volumes of an IPA solution. Reduction of coal tar concentrations in water leachate, attributed to the alcohol flushing, was noted in three of the four columns. The total coal tar removed from the soil columns during the IPA flushes constituted from 54 to 97% of the total coal tar removed during both water leaching (240-800 pore volumes) and alcohol flushing (1-3 pore volumes). The alcohol flushing removed from 3 to 19 % of the total coal tar in the various soil columns. Results indicated that alcohol flushing can enhance the removal of coal tar from contaminated soils and can reduce the aqueous-phase coal tar concentrations in the leachate. 16 refs., 5 figs., 3 tabs.

Adsorption and Reaction of C1-C3 Alcohols over CeOx(111) Thin Films  

SciTech Connect (OSTI)

This study reports the interaction of methanol, ethanol, 1-propanol, and 2-propanol with well-ordered CeO{sub 2}(111) thin film surfaces. All of the alcohols adsorb at low temperature by forming alkoxy and hydroxyl species on the surface. On fully oxidized CeO{sub 2}(111), recombination occurs between some of the alkoxys and hydroxyls, resulting in alcohol desorption near 220 K. At the same temperature, some of the surface hydroxyls disproportionate to produce water and the loss of lattice O. The remaining alkoxys react above 550 K. The primary alcohols favor dehydrogenation products (aldehydes). There is a net loss of O from the system, resulting in a reduction of the ceria. The secondary alcohol, 2-propanol, undergoes primarily dehydration, producing propene with no net change in the cerium oxidation state. Reduced CeO{sub x}(111) competes with the gaseous products for available O. Little or no water is produced. The reaction selectivity for the C{sub 2} and C{sub 3} alcohols shifts toward favoring dehydration products. The loss of O from the alcohols leads to oxidation of the reduced ceria. Compared with the oxidized surface, the alkene desorption shifts to lower temperature, whereas the aldehyde desorption shifts to higher temperature. This indicates that, on the reduced surface, it is easier to break the C-O bond but more difficult to break the O-substrate bond.

Alcohol-based fuels from syngases. [Alkanol fuels  

SciTech Connect (OSTI)

Explains how a mixture of methanol and C/sub 2/-C/sub 6/ saturated alcohols (Alkanol fuel) has the potential for providing a gasoline-blending stock superior to that of straight-run methanol or ethanol. Summarizes the technical and economic advantages of producing and utilizing Alkanol fuels. Although methanol is cheaper, Alkanols represent a higher-quality fuel product with lower-oxygen content and higher hydrogen content. Increasing the methanol content of the Alkanol mixture has the potential to reduce the Alkanols cost of production to the equivalent of that of methanol on a constant heating value basis. The optimal composition will depend on production costs as well as on the properties of Alkanol mixtures necessary to generate a premium, synthetic transportation fuel. The Mobil M-Gasoline Process is an alternative route to converting methanol to synthetic transportation fuels. Concludes that development of the Alkanols Process is in its early stages and further work needs to be done in identifying and solving potential technical bottlenecks related to catalyst stability/selectivity and recovery of water-free Alkanol fuel mixtures. Current work is involved in the study of the performance and stability of several catalyst candidates utilizing a slurry reaction system and in the identification of optimal compositions of Alkanols for use as gasoline blending stocks.

Sub-crop geologic map of pre-Tertiary rocks in the Yucca Flat and northern Frenchman Flat areas, Nevada Test Site, southern Nevada  

SciTech Connect (OSTI)

This map displays interpreted structural and stratigraphic relations among the Paleozoic and older rocks of the Nevada Test Site region beneath the Miocene volcanic rocks and younger alluvium in the Yucca Flat and northern Frenchman Flat basins. These interpretations are based on a comprehensive examination and review of data for more than 77 drillholes that penetrated part of the pre-Tertiary basement beneath these post-middle Miocene structural basins. Biostratigraphic data from conodont fossils were newly obtained for 31 of these holes, and a thorough review of all prior microfossil paleontologic data is incorporated in the analysis. Subsurface relationships are interpreted in light of a revised regional geologic framework synthesized from detailed geologic mapping in the ranges surrounding Yucca Flat, from comprehensive stratigraphic studies in the region, and from additional detailed field studies on and around the Nevada Test Site. All available data indicate the subsurface geology of Yucca Flat is considerably more complicated than previous interpretations have suggested. The western part of the basin, in particular, is underlain by relics of the eastward-vergent Belted Range thrust system that are folded back toward the west and thrust by local, west-vergent contractional structures of the CP thrust system. Field evidence from the ranges surrounding the north end of Yucca Flat indicate that two significant strike-slip faults track southward beneath the post-middle Miocene basin fill, but their subsurface traces cannot be closely defined from the available evidence. In contrast, the eastern part of the Yucca Flat basin is interpreted to be underlain by a fairly simple north-trending, broad syncline in the pre-Tertiary units. Far fewer data are available for the northern Frenchman Flat basin, but regional analysis indicates the pre-Tertiary structure there should also be relatively simple and not affected by thrusting. This new interpretation has implications for ground water flow through pre-Tertiary rocks beneath the Yucca Flat and northern Frenchman Flat areas, and has consequences for ground water modeling and model validation. Our data indicate that the Mississippian Chainman Shale is not laterally extensive confining unit in the western part of the basin because it is folded back onto itself by the convergent structures of the Belted Range and CP thrust systems. Early and Middle Paleozoic limestone and dolomite are present beneath most of both basins and, regardless of structural complications, are interpreted to form a laterally continuous and extensive carbonate aquifer. Structural culmination that marks the French Peak accommodation zone along the topographic divide between the two basins provides a lateral pathway through highly fractured rock between the volcanic aquifers of Yucca Flat and the regional carbonate aquifer. This pathway may accelerate the migration of ground-water contaminants introduced by underground nuclear testing toward discharge areas beyond the Nevada Test Site boundaries. Predictive three-dimensional models of hydrostratigraphic units and ground-water flow in the pre-Tertiary rocks of subsurface Yucca Flat are likely to be unrealistic due to the extreme structural complexities. The interpretation of hydrologic and geochemical data obtained from monitoring wells will be difficult to extrapolate through the flow system until more is known about the continuity of hydrostratigraphic units. 1 plate

Pancreatic injury in hepatic alcohol dehydrogenase-deficient deer mice after subchronic exposure to ethanol  

SciTech Connect (OSTI)

Pancreatitis caused by activation of digestive zymogens in the exocrine pancreas is a serious chronic health problem in alcoholic patients. However, mechanism of alcoholic pancreatitis remains obscure due to lack of a suitable animal model. Earlier, we reported pancreatic injury and substantial increases in endogenous formation of fatty acid ethyl esters (FAEEs) in the pancreas of hepatic alcohol dehydrogenase (ADH)-deficient (ADH{sup -}) deer mice fed 4% ethanol. To understand the mechanism of alcoholic pancreatitis, we evaluated dose-dependent metabolism of ethanol and related pancreatic injury in ADH{sup -} and hepatic ADH-normal (ADH{sup +}) deer mice fed 1%, 2% or 3.5% ethanol via Lieber-DeCarli liquid diet daily for 2 months. Blood alcohol concentration (BAC) was remarkably increased and the concentration was {approx} 1.5-fold greater in ADH{sup -} vs. ADH{sup +} deer mice fed 3.5% ethanol. At the end of the experiment, remarkable increases in pancreatic FAEEs and significant pancreatic injury indicated by the presence of prominent perinuclear space, pyknotic nuclei, apoptotic bodies and dilation of glandular ER were found only in ADH{sup -} deer mice fed 3.5% ethanol. This pancreatic injury was further supported by increased plasma lipase and pancreatic cathepsin B (a lysosomal hydrolase capable of activating trypsinogen), trypsinogen activation peptide (by-product of trypsinogen activation process) and glucose-regulated protein 78 (endoplasmic reticulum stress marker). These findings suggest that ADH-deficiency and high alcohol levels in the body are the key factors in ethanol-induced pancreatic injury. Therefore, determining how this early stage of pancreatic injury advances to inflammation stage could be important for understanding the mechanism(s) of alcoholic pancreatitis.

Treating isopropyl alcohol by a regenerative catalytic oxidizer  

Science Journals Connector (OSTI)

Regenerative catalytic oxidizer (RCO) can be conveniently used to control emissions of volatile organic compounds (VOCs), because of their thermal recovery efficiency (TRE), low fuel cost and high oxidation. In this work, catalysts with various metal weight loadings were prepared by deposition–precipitation, wet impregnation and incipient impregnation to treat isopropyl alcohol (IPA). We used the excellent catalytic performance in a pilot RCO to test IPA oxidation performance under various conditions. The best catalyst was selected and its TRE, bed temperature variations, pressure drops and selectivity of the catalyst were more widely discussed. The results demonstrate that the optimal catalyst was prepared by wet impregnation with 20 wt.% metal on ceramic honeycomb (CH). 20 wt.% Cu–Co/(CH) catalyst was the best catalyst used in a RCO because it was effective in treating IPA, with a CO2 yield of up to 95% at a heating zone temperature (Tset) = 400 °C under various conditions. It also had the largest tolerance of variations in inlet IPA concentration and gas velocity (Ug). This 20 wt.% Cu–Co/(CH) catalyst in a RCO performed well in terms of TRE, pressure drop and selectivity to CO2. The TRE range in a RCO was from 87.8 to 91.2% under various conditions, and decreased as Ug increased in a fixed Tset. The pressure drop increased with Ug and Tset. The selectivity to CO2 increased to over 95% at 300 °C, and that to propene remained at 2–5% from 200 to 400 °C. Finally, the stability test results indicated that the 20 wt.% Cu–Co/(CH) catalyst was very stable at various CO2 yields and temperatures.

Restraint stress exacerbates alcohol-induced reproductive toxicity in male rats  

Science Journals Connector (OSTI)

Abstract Cumulative exposure to multiple stresses may lead to aggravating the toxicity of each stress, qualitatively or quantitatively altering biological responses because of toxicological interaction. In this study, we intended to determine the possible effects of restraint stress on reproductive toxicity due to ethanol usage in male rats. Early pubertal male Wistar rats were subjected to either restraint stress (5 h/day) or alcohol intoxication (2 mg/kg body weight) or both for 60 days. Body weights of control and experimental rats were similar during the 60 days of this study. Testes were harvested, weighed, and prepared for enzyme assays, and cauda epididymides were isolated for the determination of density, motility, and viability of stored spermatozoa. Restraint stress or alcohol treatment significantly reduced testis weight and caused significant reductions in steroidogenesis and spermatogenesis. Mean density, motility, and viability of stored spermatozoa were reduced in experimental rats. Plasma testosterone concentrations in rats subjected to restraint stress or alcohol were decreased compared with those of controls, concomitant with increased concentrations of LH and FSH in experimental rats. These data suggest that sub-chronic exposure to restraint stress or alcohol contribute to reduce testicular and epididymal function in exposed rats. The study also suggests that restraint stress exacerbates alcohol-induced reproductive toxicity in rats.

Traumatic brain injury induces neuroinflammation and neuronal degeneration that is associated with escalated alcohol self-administration in rats  

Science Journals Connector (OSTI)

AbstractBackground Traumatic brain injury (TBI) affects millions of people each year and is characterized by direct tissue injury followed by a neuroinflammatory response. The post-TBI recovery period can be associated with a negative emotional state characterized by alterations in affective behaviors implicated in the development of Alcohol Use Disorder in humans. The aim of this study was to test the hypothesis that post-TBI neuroinflammation is associated with behavioral dysfunction, including escalated alcohol intake. Methods Adult male Wistar rats were trained to self-administer alcohol prior to counterbalanced assignment into naïve, craniotomy, and TBI groups by baseline drinking. TBI was produced by lateral fluid percussion (LFP; >2 ATM; 25 ms). Alcohol drinking and neurobehavioral function were measured at baseline and following TBI in all experimental groups. Markers of neuroinflammation (GFAP and ED1) and neurodegeneration (FJC) were determined by fluorescence histochemistry in brains excised at sacrifice 19 days post-TBI. Results The cumulative increase in alcohol intake over the 15 days post-TBI was greater in TBI animals compared to naïve controls. A higher rate of pre-injury alcohol intake was associated with a greater increase in post-injury alcohol intake in both TBI and craniotomy animals. Immediately following TBI, both TBI and craniotomy animals exhibited greater neurobehavioral dysfunction compared to naïve animals. GFAP, IBA-1, ED1, and FJC immunoreactivity at 19 days post-TBI was significantly higher in brains from TBI animals compared to both craniotomy and naïve animals. Conclusions These results show an association between post-TBI escalation of alcohol drinking and marked localized neuroinflammation at the site of injury. Moreover, these results highlight the relevance of baseline alcohol preference in determining post-TBI alcohol drinking. Further investigation to determine the contribution of neuroinflammation to increased alcohol drinking post-TBI is warranted.

Maternal Risk Factors for Fetal Alcohol Spectrum Disorders in a Province in Italy  

Science Journals Connector (OSTI)

AbstractBackground Maternal risk factors for fetal alcohol spectrum disorders (FASD) in Italy and Mediterranean cultures need clarification, as there are few studies and most are plagued by inaccurate reporting of antenatal alcohol use. Methods Maternal interviews (n = 905) were carried out in a population-based study of the prevalence and characteristics of FASD in the Lazio region of Italy which provided data for multivariate case control comparisons and multiple correlation models. Results Case control findings from interviews seven years post-partum indicate that mothers of children with FASD are significantly more likely than randomly-selected controls or community mothers to: be shorter; have higher body mass indexes (BMI); be married to a man with legal problems; report more drinking three months pre-pregnancy; engage in more current drinking and drinking alone; and have alcohol problems in her family. Logistic regression analysis of multiple candidate predictors of a FASD diagnosis indicates that alcohol problems in the child's family is the most significant risk factor, making a diagnosis within the continuum of FASD 9 times more likely (95% C.I. = 1.6 to 50.7). Sequential multiple regression analysis of the child's neuropsychological performance also identifies alcohol problems in the child's family as the only significant maternal risk variable (p<.001) when controlling for other potential risk factors. Conclusions Underreporting of prenatal alcohol use has been demonstrated among Italian and other Mediterranean antenatal samples, and it was suspected in this sample. Nevertheless, several significant maternal risk factors for FASD have been identified.

Variations in Mg/Ca as a control on distribution of strontium concentrations and delta/sup 18/O in upper Tertiary dolomites from Bahamas  

SciTech Connect (OSTI)

Strontium concentrations and delta/sup 18/O are commonly used to infer the gross composition of dolomitizing waters, yet the bases for such inferences are not firmly established. A new approach to calibrating these 2 parameters is suggested from analyses of a section of upper Tertiary dolomites from the Bahamas. In an interval of dolomite, 120 m (394 ft) from a core taken on San Salvador Island, mole % MgCO/sub 3/ is correlated positively with delta/sup 18/O, and negatively with strontium. Strontium substitutes mainly for calcium, thus the negative correlation with mole % MgCO/sub 3/. Dolomites are enriched between 3 to 7% in delta/sup 18/O as compared with coprecipitated calcite, and thus the positive correlation. These two covariations indicate the need to consider the stoichiometric coefficient of dolomites, and to normalize strontium concentrations and delta/sup 18/O with their respective stoichiometric coefficients before inferring their relationship with fluid composition.

Nonassociated gas resources in low-permeability sandstone reservoirs, lower tertiary Wasatch Formation, and upper Cretaceous Mesaverde Group, Uinta Basin, Utah  

SciTech Connect (OSTI)

The US Geological Survey recognizes six major plays for nonassociated gas in Tertiary and Upper Cretaceous low-permeability strata of the Uinta Basin, Utah. For purposes of this study, plays without gas/water contacts are separated from those with such contacts. Continuous-saturation accumulations are essentially single fields, so large in areal extent and so heterogeneous that their development cannot be properly modeled as field growth. Fields developed in gas-saturated plays are not restricted to structural or stratigraphic traps and they are developed in any structural position where permeability conduits occur such as that provided by natural open fractures. Other fields in the basin have gas/water contacts and the rocks are water-bearing away from structural culmination`s. The plays can be assigned to two groups. Group 1 plays are those in which gas/water contacts are rare to absent and the strata are gas saturated. Group 2 plays contain reservoirs in which both gas-saturated strata and rocks with gas/water contacts seem to coexist. Most units in the basin that have received a Federal Energy Regulatory Commission (FERC) designation as tight are in the main producing areas and are within Group 1 plays. Some rocks in Group 2 plays may not meet FERC requirements as tight reservoirs. However, we suggest that in the Uinta Basin that the extent of low-permeability rocks, and therefore resources, extends well beyond the limits of current FERC designated boundaries for tight reservoirs. Potential additions to gas reserves from gas-saturated tight reservoirs in the Tertiary Wasatch Formation and Cretaceous Mesaverde Group in the Uinta Basin, Utah is 10 TCF. If the potential additions to reserves in strata in which both gas-saturated and free water-bearing rocks exist are added to those of Group 1 plays, the volume is 13 TCF.

Alcohol Quantity and Type on Risk of Recurrent Gout Attacks: An Internet-based Case-crossover Study  

Science Journals Connector (OSTI)

AbstractObjectives Although beer and liquor have been associated with risk of incident gout, wine has not. Yet anecdotally, wine is thought to trigger gout attacks. Further, how much alcohol intake is needed to increase the risk of gout attack is not known. We examined the quantity and type of alcohol consumed on risk of recurrent gout attacks. Methods We conducted a prospective Internet-based case-crossover study in the US among participants with gout and who had at least one attack during the 1 year of follow-up. We evaluated the association of alcohol intake over the prior 24 hours as well as the type of alcoholic beverage with risk of recurrent gout attack, adjusting for potential time-varying confounders. Results This study included 724 participants with gout (78% men, mean age 54 years). There was a significant dose-response relationship between amount of alcohol consumption and risk of recurrent gout attacks (P gout attack was 1.36 (95% confidence interval [CI], 1.00-1.88) and 1.51 (95% CI, 1.09-2.09) times higher for >1-2 and >2-4 alcoholic beverages, respectively, compared with no alcohol consumption in the prior 24 hours. Consuming wine, beer, or liquor was each associated with an increased risk of gout attack. Conclusions Episodic alcohol consumption, regardless of type of alcoholic beverage, was associated with an increased risk of recurrent gout attacks, including potentially with moderate amounts. Individuals with gout should limit alcohol intake of all types to reduce the risk of recurrent gout attacks.

Synthesis of higher alcohols from carbon monoxide and hydrogen in a slurry reactor  

SciTech Connect (OSTI)

Higher, i.e. C{sub 2{sup +}}, alcohols are desired as gasoline additives, feedstocks for producing ethers and as alternative fuels for automobiles. In all cases, the backbone branching of an alcohol improves octane rating, which is essential for good engine performance. These types of branched, higher alcohols are the desired products for a process converting synthesis gas, a CO and H{sub 2} mixture, often generated from coal gasification. Based on this premise, promoted ZnCr oxide catalysts appear to be as one of the best avenues for further investigation. Once this investigation is complete, a natural extension is to replace the Cr in the ZnCr oxide catalyst with Mo and W, both in the same elemental triad with Cr. Mo has already been shown as an active HAS catalyst, both on a SiO{sub 2} support and in the MoS{sub 2} form. The three catalyst combinations, ZnMo, ZnW, and MnCr oxides will be tested in the stirred autoclave system. However, if none of the three indicate any comparable activity and/or selectivity toward higher alcohols as compared with other HAS catalysts, then an investigation of the effects of Cs promotion on the ZnCr oxide methanol catalysts will be executed.

Raman spectroscopic measurement of oxidation in supercritical water. 2: Conversion of isopropyl alcohol to acetone  

SciTech Connect (OSTI)

The oxidation of isopropyl alcohol in supercritical water has been investigated using Raman spectroscopy. Results for species concentration as a function of residence-time are presented for temperatures ranging from 400 to 480 C at constant pressure, 24.4 {+-} 0.3 MPa, and constant equivalence ratio, 0.88 {+-} 0.0. Acetone has been identified as the principal intermediate formed and subsequently destroyed, during the oxidation process. By assuming first-order kinetics for the destruction of both isopropyl alcohol and acetone, effective first-order rate constants have been determined from fits of the experimental data. Assuming Arrhenius behavior, the fits yield rate constants for isopropyl alcohol, k{sub eff,ipa} = 3.255 {times} 10{sup 22}(s{sup {minus}1}) exp [{minus}301.1 (kJ/mol)/RT], and for acetone, k{sub eff,ace} = 1.948 {times} 10{sup 10}(s{sup {minus}1}) exp[{minus}137.7(kJ/mol)/RT]. These results indicate that for temperatures greater than 425 C, the destruction of isopropyl alcohol proceeds faster than that of acetone.

Thermal Processing Techniques to Improve Metal Sulfide Mixed Alcohol Catalyst Performance  

SciTech Connect (OSTI)

Research over several decades by several institutions has shown that alkali-promoted metal sulfide catalysts are capable of producing mixed alcohols from syngas with high selectivity and yield. Unfortunately, process models suggest that syngas to mixed alcohol processes, and especially thermochemical biomass to mixed alcohol processes, require improvements to sulfide catalyst activity and/or selectivity for acceptable economics. These improvements, if incremental, cannot result in increased process complexity, capital expenditure, or catalyst costs. It is well accepted among catalyst researchers that thermal processing techniques like calcining and reduction can have profound effects on the properties and performance of finished catalysts, and that small variations in thermal processing do not usually affect the overall cost of the catalyst. Metal sulfide catalysts are no exception but surprisingly, little attention has been given to the effects of thermal treatment on bulk metal sulfide mixed alcohol catalysts. This presentation will discuss how parameters like temperature, dwell time, metal ratios, and purge gas affect the performance and physical properties of K-Co/Mo catalysts.

Factors controlling reservoir quality in tertiary sandstones and their significance to geopressured geothermal production. Annual report, May 1, 1979-May 31, 1980  

SciTech Connect (OSTI)

Differing extents of diagenetic modification is the factor primarily responsible for contrasting regional reservoir quality of Tertiary sandstones from the Upper and Lower Texas Gulf Coast. Detailed comparison of Frio sandstones from the Chocolate Bayou/Danbury Dome area, Brazoria County, and Vicksburg sandstones from the McAllen Ranch Field area, Hidalgo County, reveals that extent of diagenetic modification is most strongly influenced by (1) detrital mineralogy and (2) regional geothermal gradients. Vicksburg sandstones from the McAllen Ranch Field area are less stable, chemically and mechanically, than Frio sandstones from the Chocolate Bayou/Danbury dome area. Vicksburg sandstones are mineralogically immature and contain greater proportions of feldspars and rock fragments than do Frio sandstones. Thr reactive detrital assemblage of Vicksubrg sandstones is highly susceptible to diagenetic modification. Susceptibility is enhanced by higher than normal geothermal gradients in the McAllen Ranch Field area. Thus, consolidation of Vicksburg sandstones began at shallower depth of burial and precipitation of authigenic phases (especially calcite) was more pervasive than in Frio sandstones. Moreover, the late-stage episode of ferroan calcite precipitation that occluded most secondary porosity in Vicksburg sandstones did not occur significantly in Frio sandstones. Therefore, regional reservoir quality of Frio sandstones from Brazoria County is far better than that characterizing Vicksburg sandstones from Hidalgo County, especially at depths suitable for geopressured geothermal energy production.

Compound “J” in Late Cretaceous/Tertiary terrigenous oils revisited: Structure elucidation of a rearranged oleanane coeluting on GC with 18?(H)-oleanane  

Science Journals Connector (OSTI)

Abstract A C30 pentacyclic triterpane eluting slightly after 18?(H)-oleanane in the m/z 191 mass chromatograms of Late Cretaceous/Tertiary terrigenous oils (peak “J” in the early literature) has been isolated from a Niger Delta oil and identified using NMR spectroscopy as 3?-methyl-24-nor-18?(H)-oleanane. The previous assignment as 18?(H)-oleanane is therefore partly erroneous. 3?-Methyl-24-nor-18?(H)-oleanane affords a larger m/z 412 ? 356 response than the oleananes and the relative contribution of 3?-methyl-24-nor-18?(H)-oleanane to the 412 ? 191 “oleanane peak” can be roughly estimated from comparison of the 412 ? 356/412 ? 191 ratio from the oleanane peak with that of the pure compounds. 3?-Methyl-24-nor-18?(H)-oleanane can be as abundant as 18?(H)-oleanane in oils having a high concentration of early eluting rearranged oleananes. 3?-Methyl-24-nor-19?(H)-taraxastane was also tentatively assigned in the oils on the basis of its mass spectrum as well as its gas chromatography and high performance liquid chromatography retention times. 3?-Methyl-24-nor-gammacerane was tentatively assigned in a similar way in an oil containing gammacerane. All 3?-methyl-24-nor-triterpanes could be formed via dehydration, rearrangement and hydrogenation of triterpenoids having an OH group at C-3.

Hybridization of sugar alcohols into brucite interlayers via a melt intercalation process  

Science Journals Connector (OSTI)

We report the preparation of organic-brucite (BR) hybrids using harmless sugar alcohols (xylitol, XYL, and sorbitol, SOR). Since XYL and SOR are solid materials at room temperature, the hybridization was investigated by comparing two separate methods, hydrothermal treatment and melt mixing. BR-sugar alcohol hybrids were successfully prepared by a melt intercalation method at 175 °C. X-ray diffraction and Fourier transform infrared spectroscopy analyses indicated that organic molecules were intercalated into the brucite layers, overcoming the barrier of hydroxyl bonds between the BR layers. Moreover, X-ray photoelectron spectroscopy and thermal analyses showed that the intercalated materials at 175 °C resulted in the formation of covalent Mg–O–C bond linkages on the interlayer surface of BR.

Raman spectra of first order longitudinal optical phonon peak has been analyzed using phonon dispersion model to detect the surface phonon modes in CdS nanoneedles and wires. The origin of negative differential resistance behavior in current-voltage characteristics for junctionlike CdS nanocomposites has been discussed.

Homogeneous nucleation rates of higher n -alcohols measured in a laminar flow diffusion chamber  

Science Journals Connector (OSTI)

Nucleation rate isotherms of n-butanol n-pentanol n-hexanol n-heptanol and n-octanol were measured in a laminar flowdiffusion chamber using helium as carrier gas. The measurements were made at 250–310 K corresponding to reduced temperatures of 0.43–0.50 and at atmospheric pressure. Experimental nucleation rate range was from 10 3 to 10 7 ? cm ?3 ? s ?1 . The expression and accuracy of thermodynamic parameters in particular equilibrium vapor pressure were found to have a significant effect on calculated nucleation rates. The results were compared to the classical nucleation theory (CNT) the self-consistency corrected classical theory (SCC) and the Hale’s scaled model of the CNT. The average ratio between the experimental and theoretical nucleation rates for all alcohols used was 1.5×10 3 when the CNT was used and 0.2×10 ?1 when the SCC was used and 0.7×10 ?1 when the Hale’s scaled theory was used. The average values represent all the alcohols used at the same reduced temperatures. The average ratio was about the same throughout the temperature range although J exp /J the calculated with the Hale’s scaled theory increased slightly with increasing temperature. The saturation ratio dependency was predicted closest to experiment with the classical nucleation theory. The nucleation rates were compared to those found in the literature. The measurements were in reasonable agreement with each other. The molecular content of critical alcohol clusters was between 35 and 80 molecules. At a fixed reduced temperature the number of molecules in a critical cluster decreased as a function of alcohol carbon chain length. The number of molecules in critical clusters was compared to those predicted by the Kelvin equation. The theory predicted the critical cluster sizes well.

Monohydroxy alcohols show a structural relaxation and at longer time scales a Debye-type dielectric peak. From spin-lattice relaxation experiments using different nuclear probes an intermediate, slower-than-structural dynamics is identified for n-butanol. Based on these findings and on diffusion measurements, a model of self-restructuring, transient chains is proposed. The model is demonstrated to explain consistently the so far puzzling observations made for this class of hydrogen-bonded glass forming liquids.

Neutron-reflectometry study of alcohol adsorption on various DLC coatings  

Science Journals Connector (OSTI)

Abstract Diamond-like carbon (DLC) coatings are notable for their excellent tribological properties. Our understanding of the lubrication of DLC coatings has improved drastically over the past decade. However, only a few details are known about the properties of the adsorbed layers on DLC, which crucially affect their tribological properties under lubricated conditions. In this work we used neutron reflectometry to determine the thickness and the density of adsorbed layers of alcohol molecules on several different types of DLC coatings, i.e., non-hydrogenated (a-C) and hydrogenated, of which both non-doped (a-C:H) and doped (a-C:H:F and a-C:H:Si) coatings were used. The results showed that a 0.9-nm-thick and relatively dense (?45%) layer of alcohol adsorbed on the a-C coating. In contrast, no adsorption layer was found on the a-C:H, confirming the important role of hydrogen, which predominantly acts as a dangling-bond passivation source and affects the reactivity and tribochemistry of DLC coatings. The incorporation of F into a DLC coating also did not cause an increase in the adsorption ability with respect to alcohol molecules. On the contrary, the incorporation of Si increased the reactivity of the DLC coating so that a 1.3-nm-thick alcohol layer with a 35% bulk density was detected on the surface. We also discuss the very good agreement of the current results with the surface energy of selected coatings found in these experiments.

Correlation between speciated hydrocarbon emissions and flame ionization detector response for gasoline/alcohol blends .  

SciTech Connect (OSTI)

The U.S. renewable fuel standard has made it a requirement to increase the production of ethanol and advanced biofuels to 36 billion by 2022. Ethanol will be capped at 15 billion, which leaves 21 billion to come from other sources such as butanol. Butanol has a higher energy density and lower affinity for water than ethanol. Moreover, alcohol fueled engines in general have been shown to positively affect engine-out emissions of oxides of nitrogen and carbon monoxide compared with their gasoline fueled counterparts. In light of these developments, the variety and blend levels of oxygenated constituents is likely to increase in the foreseeable future. The effect on engine-out emissions for total hydrocarbons is less clear due to the relative insensitivity of the flame ionization detector (FID) toward alcohols and aldehydes. It is well documented that hydrocarbon (HC) measurement using a conventional FID in the presence of oxygenates in the engine exhaust stream can lead to a misinterpretation of HC emissions trends for alcohol fuel blends. Characterization of the exhaust stream for all expected hydrocarbon constituents is required to accurately determine the actual concentration of unburned fuel components in the exhaust. In addition to a conventional exhaust emissions bench, this characterization requires supplementary instrumentation capable of hydrocarbon speciation and response factor independent quantification. Although required for certification testing, this sort of instrumentation is not yet widely available in engine development facilities. Therefore, an attempt is made to empirically determine FID correction factors for oxygenate fuels. Exhaust emissions of an engine fueled with several blends of gasoline and ethanol, n-butanol and iso-Butanol were characterized using both a conventional FID and a Fourier transform infrared. Based on these results, a response factor predicting the actual hydrocarbon emissions based solely on FID results as a function of alcohol type and content is presented. Finally, the correlation derived from data presented in this study is compared with equations and results found in the literature.

Adsorption and Reaction of C(1)-C(3) Alcohols over CeO(x)(111) Thin Films  

SciTech Connect (OSTI)

This study reports the interaction of methanol, ethanol, 1-propanol, and 2-propanol with well-ordered CeO{sub 2}(111) thin film surfaces. All of the alcohols adsorb at low temperature by forming alkoxy and hydroxyl species on the surface. On fully oxidized CeO{sub 2}(111), recombination occurs between some of the alkoxys and hydroxyls, resulting in alcohol desorption near 220 K. At the same temperature, some of the surface hydroxyls disproportionate to produce water and the loss of lattice O. The remaining alkoxys react above 550 K. The primary alcohols favor dehydrogenation products (aldehydes). There is a net loss of O from the system, resulting in a reduction of the ceria. The secondary alcohol, 2-propanol, undergoes primarily dehydration, producing propene with no net change in the cerium oxidation state. Reduced CeO{sub X}(111) competes with the gaseous products for available O. Little or no water is produced. The reaction selectivity for the C{sub 2} and C{sub 3} alcohols shifts toward favoring dehydration products. The loss of O from the alcohols leads to oxidation of the reduced ceria. Compared with the oxidized surface, the alkene desorption shifts to lower temperature, whereas the aldehyde desorption shifts to higher temperature. This indicates that, on the reduced surface, it is easier to break the C-O bond but more difficult to break the O-substrate bond.

Oxidation, Reduction, and Condensation of Alcohols over (MO3)3 (M=Mo, W) Nanoclusters  

SciTech Connect (OSTI)

The reactions of deuterated methanol, ethanol, 1-propanol, 1-butanol, 2-propanol, 2-butanol and t-butanol over cyclic (MO3)3 (M = Mo, W) clusters were studied experimentally with temperature programmed desorption (TPD) and theoretically with coupled cluster CCSD(T) theory and density functional theory. The reactions of two alcohols per M3O9 cluster are required to provide agreement with experiment for D2O release, dehydrogenation and dehydration. The reaction begins with the elimination of water by proton transfers and forms an intermediate dialkoxy species which can undergo further reaction. Dehydration proceeds by a ? hydrogen transfer to a terminal M=O. Dehydrogenation takes place via an ? hydrogen transfer to an adjacent MoVI = O atom or a WVI metal center with redox involved for M = Mo and no redox for M = W. The two channels have comparable activation energies. H/D exchange to produce alcohols can take place after olefin is released or via the dialkoxy species depending on the alcohol and the cluster. The Lewis acidity of the metal center with WVI being larger than MoVI results in the increased reactivity of W3O9 over Mo3O9 for dehydrogenation and dehydration.

Activation of farnesoid X receptor attenuates hepatic injury in a murine model of alcoholic liver disease  

SciTech Connect (OSTI)

Highlights: •FXR activity was impaired by chronic ethanol ingestion in a murine model of ALD. •Activation of FXR attenuated alcohol-induced liver injury and steatosis. •Activation of FXR attenuated cholestasis and oxidative stress in mouse liver. -- Abstract: Alcoholic liver disease (ALD) is a common cause of advanced liver disease, and considered as a major risk factor of morbidity and mortality worldwide. Hepatic cholestasis is a pathophysiological feature observed in all stages of ALD. The farnesoid X receptor (FXR) is a member of the nuclear hormone receptor superfamily, and plays an essential role in the regulation of bile acid, lipid and glucose homeostasis. However, the role of FXR in the pathogenesis and progression of ALD remains largely unknown. Mice were fed Lieber-DeCarli ethanol diet or an isocaloric control diet. We used a specific agonist of FXR WAY-362450 to study the effect of pharmacological activation of FXR in alcoholic liver disease. In this study, we demonstrated that FXR activity was impaired by chronic ethanol ingestion in a murine model of ALD. Activation of FXR by specific agonist WAY-362450 protected mice from the development of ALD. We also found that WAY-362450 treatment rescued FXR activity, suppressed ethanol-induced Cyp2e1 up-regulation and attenuated oxidative stress in liver. Our results highlight a key role of FXR in the modulation of ALD development, and propose specific FXR agonists for the treatment of ALD patients.

The Hispanic Americans Baseline Alcohol Survey (HABLAS): Rates and predictors of DUI across Hispanic national groups  

Science Journals Connector (OSTI)

This paper examines rates of self-reported driving under the influence (DUI) of alcohol and 12-month and lifetime DUI arrest rates among Mexican Americans, Puerto Ricans, Cuban Americans and South/Central Americans in the U.S. population. Using a multistage cluster sample design, a total of 5224 individuals 18 years of age and older were selected from the household population in five metropolitan areas of the U.S.: Miami, New York, Philadelphia, Houston and Los Angeles. The survey weighted response rate was 76%. Among men, 21% of Mexican Americans, 19.9% of South/Central Americans, 11.6% of Puerto Ricans and 6.9% of Cuban Americans reported DUI. Rates were lower among women, ranging from 9.7% for Mexican Americans to 1.3% for Cuban Americans. Mexican American men had the highest 12-month arrest rate (1.6%) and the highest lifetime arrest rate (11.2%). Drinkers who reported DUI were heavier drinkers than those not reporting DUI according to a variety of indicators. However, most DUI incidents involved non-alcohol-dependent drivers. Mexican Americans and South Central/Americans, men, younger drivers, those with less than high school education, those with higher income and higher alcohol consumption were more likely to report DUI and DUI arrests. These findings show that Hispanic national groups in the U.S. are diverse regarding drinking and DUI-related experiences.

Nonphosphate Degradation Products of Tributyl Phosphate and Their Reactivities in Purex Media Under Extreme Conditions  

SciTech Connect (OSTI)

The chemical degradation of tributyl phosphate (TBP) in liquid systems, where TBP was in contact with aqueous solutions containing nitric acid and/or uranyl nitrate, was studied experimentally to clarify the mechanisms of the formation and successive reactions of nonphosphate products under atmospheric pressure. Butyl nitrate, propionic acid, acetic acid, butric acid, and butyl alcohol were formed as the nonphosphate butyl products derived from the butyl-groups of TBP in an open system. The total amount of these products almost equals the amount of the major intermediate phosphate products reduced, i.e., di- and monobutyl phosphates and phosphoric acid. Butyl alcohol was found to be the precursor of the other nonphosphate products.Even when the extremely degraded solvent was further contacted with 10 M nitric acid at 90 deg. C, no significant heat evolution was observed at atmospheric pressure. Only butyl alcohol changed into carboxylic acids by exothermic oxidative reactions.

The effects of acute alcohol exposure on the response properties of neurons in visual cortex area 17 of cats  

SciTech Connect (OSTI)

Physiological and behavioral studies have demonstrated that a number of visual functions such as visual acuity, contrast sensitivity, and motion perception can be impaired by acute alcohol exposure. The orientation- and direction-selective responses of cells in primary visual cortex are thought to participate in the perception of form and motion. To investigate how orientation selectivity and direction selectivity of neurons are influenced by acute alcohol exposure in vivo, we used the extracellular single-unit recording technique to examine the response properties of neurons in primary visual cortex (A17) of adult cats. We found that alcohol reduces spontaneous activity, visual evoked unit responses, the signal-to-noise ratio, and orientation selectivity of A17 cells. In addition, small but detectable changes in both the preferred orientation/direction and the bandwidth of the orientation tuning curve of strongly orientation-biased A17 cells were observed after acute alcohol administration. Our findings may provide physiological evidence for some alcohol-related deficits in visual function observed in behavioral studies.

Vehicle-emission characteristics using mechanically emulsified alcohol/diesel fuels  

SciTech Connect (OSTI)

A light-duty diesel vehicle fueled with an emulsified alcohol/diesel fuel was operated under cyclic mode. Emission and fuel economy measurements were taken during vehicle operation. The test results showed the volumetric fuel economy decreased slightly. Carbon monoxide emissions increased slightly, and oxides of nitrogen showed no significant change. Particulate emissions were reduced slightly, and the particulate extractables increased slightly. The environmental effect of these data cancel each other resulting in no significant changes in the total release of biological activity into the environment.

Hydrogen-bond equilibria and life times in a supercooled monohydroxy alcohol  

E-Print Network [OSTI]

Dielectric loss spectra covering 13 decades in frequency were collected for 2-ethyl-1-hexanol, a monohydroxy alcohol that exhibits a prominent Debye-like relaxation, typical for several classes of hydrogen-bonded liquids. The thermal variation of the dielectric absorption amplitude agrees well with that of the hydrogen-bond equilibrium population, experimentally mapped out using near infrared (NIR) and nuclear magnetic resonance (NMR) measurements. Despite this agreement, temperature-jump NIR spectroscopy reveals that the hydrogen-bond switching rate does not define the frequency position of the prominent absorption peak. This contrasts with widespread notions and models based thereon, but is consistent with a recent approach.

High octane ethers from synthesis gas-derived alcohols. Quarterly technical progress report, April--June 1993  

SciTech Connect (OSTI)

The results shown in Figures 10 and 11 demonstrate that the formation of butenes was very sensitive to the alcohol partial pressure. A small elevation of the alcohol pressure suppressed the formation of butenes rather drastically at both 90 and 117{degree}C. The synthesis rates of DME, MIBE, and MTBE ethers were not significantly affected at 90{degree}C, although there was a trend to increase the space time yield of DME as the alcohol pressure was increased. At the reaction temperature of 117{degree}C, all of the ethers showed increasing productivities as the pressure of the reactants was increased (Figure 11). An isotope labelling experiment was carried out to provide mechanistic insight into the manner in which methanol and isobutanol react together to form DME, MIBE, and MTBE ethers and to determine if MTBE were derived from MIBE.

CRC fuel rating program: road octane performance of oxygenates in 1982 model cars  

SciTech Connect (OSTI)

Because of the widespread interest in the use of alcohols and ethers as gasoline blending components, this program was conducted to evaluate the effects of several oxygenates on gasoline octane performance and to evaluate the effects of car design features such as engine and transmission type. Five oxygenates were evaluated at two nominal concentrations, 5 and 10 volume%, at both regular- and premium-grade octane levels: methanol (MeOH), ethanol (ETOH), isopropanol (IPA), tertiary butanol (TBA), and methyl tertiary butyl ether (MTBE). A blend of 5% MeOH and 5 percent TBA was also tested at both octane levels. Twenty-eight unleaded fuels, including four hydrocarbon fuels, two hydrocarbon fuels plus toluene, and twenty-two oxygenated fuels, were rated in duplicate in thirty-eight cars using the Modified Uniontown Technique (CRC Designation F-28-75 described in Appendix C), plus some additional instructions. All testing was done on chassis dynamometers. Ratings were obtained at full throttle with all thirty-eight cars, and at the most critical part-throttle condition (occurring with manifold vacuum of 4 in. Hg (13.5 kPa) or greater above the full-throttle vacuum) with nine cars.

Pacific Northwest National Laboratory has been conducting research to investigate the feasibility of producing mixed alcohols from biomass-derived synthesis gas (syngas). In recent years, this research has primarily involved the further development of catalysts containing rhodium and manganese based on the results of earlier catalyst screening tests. Research during FY 2011 continued to examine the performance of RhMn catalysts on alternative supports including selected zeolite, silica, and carbon supports. Catalyst optimization continued using both the Davisil 645 and Merck Grade 7734 silica supports. Research also was initiated in FY 2011, using the both Davisil 645 silica and Hyperion CS-02C-063 carbon supports, to evaluate the potential for further improving catalyst performance, through the addition of one or two additional metals as promoters to the catalysts containing Rh, Mn, and Ir.

In recent years, this research has primarily involved the further development of catalysts containing rhodium and manganese based on the results of earlier catalyst screening tests. Testing continued in FY 2012 to further improve the Ir-promoted RhMn catalysts on both silica and carbon supports for producing mixed oxygenates from synthesis gas. This testing re-examined selected alternative silica and carbon supports to follow up on some uncertainties in the results with previous test results. Additional tests were conducted to further optimize the total and relative concentrations of Rh, Mn, and Ir, and to examine selected promoters and promoter combinations based on earlier results. To establish optimum operating conditions, the effects of the process pressure and the feed gas composition also were evaluated.

Reverse osmosis performance of modified polyvinyl alcohol thin-film composite membranes  

SciTech Connect (OSTI)

Membrane separation characteristics in the nanofiltration (NF) and reverse osmosis (RO) regions of the filtration spectrum are governed by a complex combination of both steric hindrance and surface force interactions. NF and RO membranes having surface charges show unusual selectivity behavior not predicted on the basis of physical pore size alone. Hence, practical characterizations should employ techniques to gain insight on membrane function. In this work, the separation characteristics of an anionically charged modified polyvinyl alcohol (PVA) thin-film composite membrane under different operating pressures were investigated. A qualitative measurement of the surface force interactions between solutes and membrane polymer was conducted using liquid chromatography technique. An attempt was also made to study the chlorine resistance of the composite membrane.

Factors affecting acid hydrolysis of sweet potato powder (SPP) to fermentable sugars were examined. These include HCl concentration, temperature, time, and levels of SPP. Maximum reducing sugar, reported as dextrose equivalent (DE), was detected after 24 min hydrolysis (1% SPP) in 0.034N HCl heated at 154 degrees celcius. These samples also had 3.43% hydroxymethylfurfural (HMF) based on dry weight. A high level of HMF (9.2%) was detected in 1% SPP heated at 154 degrees C in 0.10N HCl for 18 min. The lowest concentration of HMF formed (1.8%), at maximal DE of 61%, was established in samples containing 5% SPP and heated at 154 degrees C in 0.034N HCl for 48 min. Aqueous extracts of uncured SPP, examined by HPLC, contained glucose, fructose and sucrose, butdegreaded SPP had only glucose and fructose. Products of degraded SPP, under appropriate conditions, could be used for alcohol fermentation. (Refs. 18).

This project is a combination of process simulation and catalyst development aimed at identifying the most economical method for converting coal to syngas to linear higher alcohols to be used as oxygenated fuel additives. There are two tasks. The goal of Task 1 is to discover, study, and evaluate novel heterogeneous catalytic systems for the production of oxygenated fuel enhancers from synthesis gas, and to explore, analytically and on the bench scale, novel reactor and process concepts for use in converting syngas to liquid fuel products. The goal of Task 2 is to simulate, by computer, energy efficient and economically efficient processes for converting coal to energy (fuel alcohols and/or power). The primary focus is to convert syngas to fuel alcohols. This report contains results from Task 2. The first step for Task 2 was to develop computer simulations of alternative coal to syngas to linear higher alcohol processes, to evaluate and compare the economics and energy efficiency of these alternative processes, and to make a preliminary determination as to the most attractive process configuration. A benefit of this approach is that simulations will be debugged and available for use when Task 1 results are available. Seven cases were developed using different gasifier technologies, different methods for altering the H{sub 2}/CO ratio of the syngas to the desired 1.1/1, and with the higher alcohol fuel additives as primary products and as by-products of a power generation facility. Texaco, Shell, and Lurgi gasifier designs were used to test gasifying coal. Steam reforming of natural gas, sour gas shift conversion, or pressure swing adsorption were used to alter the H{sub 2}/CO ratio of the syngas. In addition, a case using only natural gas was prepared to compare coal and natural gas as a source of syngas.

From DSM-IV to DSM-5 alcohol use disorder: An overview of epidemiological data  

Science Journals Connector (OSTI)

AbstractIntroduction The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) has made several changes to criteria for alcohol use disorder (AUD). The objective of this systematic review is to assess if new DSM-5 diagnostic criteria will increase the prevalence rates of AUD in clinical and non-clinical samples as compared with DSM-IV criteria. Methods We searched PubMed, Scopus, and PsycINFO (via ProQuest) electronic databases, with no language restrictions. We included studies with data available on both DSM-IV (and DSM-IV-TR) and DSM-5 AUD in samples of adults, estimating from each study an expected increase in prevalence rates with relevant 95% confidence intervals (CIs). Results Twelve studies were included in this review. Seven studies showed an increase, two no substantial difference, and three a decrease in AUD prevalence according to DSM-5 diagnostic criteria, with differences in rates (95% CIs) varying between ? 12.4% (? 27.4 to + 5.6%) and + 61.3% (+ 46.7 to + 77.3%). Additional analyses provided confirmatory results. Conclusions DSM-5 diagnostic criteria seem to inflate prevalence rates of AUD as compared with DSM-IV. The increasing likelihood of a DSM-5 AUD diagnosis may be explained by the amount of DSM-IV ‘diagnostic orphans’ which are more prevalent than DSM-IV single-criterion alcohol abuse individuals. Further research should be aimed to study if similar trends are detectable also for other substance use disorders that experienced similar changes in DSM-5 diagnostic criteria.

Chemical behavior of degradation products of tributylphosphate in purex reprocessing  

SciTech Connect (OSTI)

Chemical behavior of butyl nitrate/butyl alcohol, degradation products from dealkylation of tri-n-butylphosphate(TBP) in PUREX reprocessing, which has not so far been reported, was investigated. No accumulation of those compounds in the organic phase of TBP(30%)-dodecane was observed in any separation cycle of PUREX despite the fact that the apparent distribution of the compounds lies to the organic phase at their high concentrations. The distribution of butyl nitrate/butyl alcohol between organic/aqueous phases is found to be dependent on their concentrations and on nitric acid concentration, which could explain the above phenomena. Only butyl nitrate of the above two compounds was slightly detected in the organic streams. It is probable from this investigation that butyl nitrate is removed into aqueous waste stream primarily through alkali scrubber.

The economical production of alcohol fuels from coal-derived synthesis gas. Sixth quarterly technical progress report, January 1, 1993--March 31, 1993  

SciTech Connect (OSTI)

Preliminary economic investigations have focused on cost reduction measures in the production of syngas from coal. A spread sheet model has been developed which can determine the cost of syngas production based upon the cost of equipment and raw materials and the market value of energy and by-products. In comparison to natural gas derived syngas, coal derived syngas is much more expensive, suggesting a questionable economic status of coal derived alcohol fuels. While it is possible that use of less expensive coal or significant integration of alcohol production and electricity production may reduce the cost of coal derived syngas, it is unlikely to be less costly to produce than syngas from natural gas. Fuels evaluation is being conducted in three parts. First, standard ASTM tests are being used to analyze the blend characteristics of higher alcohols. Second, the performance characteristics of higher alcohols are being evaluated in a single-cylinder research engine. Third, the emissions characteristics of higher alcohols are being investigated. The equipment is still under construction and the measurement techniques are still being developed. Of particular interest is n-butanol, since the MoS{sub 2} catalyst produces only linear higher alcohols. There is almost no information on the combustion and emission characteristics of n-butanol, hence the importance of gathering this information in this research.

The water footprint of biofuel produced from forest wood residue via a mixed alcohol gasification process  

Science Journals Connector (OSTI)

Forest residue has been proposed as a feasible candidate for cellulosic biofuels. However, the number of studies assessing its water use remains limited. This work aims to analyze the impacts of forest-based biofuel on water resources and quality by using a water footprint approach. A method established here is tailored to the production system, which includes softwood, hardwood, and short-rotation woody crops. The method is then applied to selected areas in the southeastern region of the United States to quantify the county-level water footprint of the biofuel produced via a mixed alcohol gasification process, under several logistic systems, and at various refinery scales. The results indicate that the blue water sourced from surface or groundwater is minimal, at 2.4 liters per liter of biofuel (l/l). The regional-average green water (rainfall) footprint falls between 400 and 443 l/l. The biofuel pathway appears to have a low nitrogen grey water footprint averaging 25 l/l at the regional level, indicating minimal impacts on water quality. Feedstock mix plays a key role in determining the magnitude and the spatial distribution of the water footprint in these regions. Compared with other potential feedstock, forest wood residue shows promise with its low blue and grey water footprint.

Endovascular Treatment of Acute Arterial Hemorrhage in Trauma Patients Using Ethylene Vinyl Alcohol Copolymer (Onyx)  

SciTech Connect (OSTI)

Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4-63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.

Alcohol fermentation of sweet potato - 1. Acid hydrolysis and factors involved  

SciTech Connect (OSTI)

Factors affecting acid hydrolysis of sweet potato powder (SPP) to fermentable sugars were examined. These include HCl concentration, temperature, time, and levels of SPP. Maximum reducing sugar, reported as dextrose equivalent (DE), was detected after 24 min hydrolysis (1% SPP) in 0.034N HCl heated at 154/degree/C. These samples also had 3.43% hydroxymethylfurfural (HMF) based on dry weight. A high level of HMF (9.2%) was detected in 1% SPP heated at 154/degree/C in 0.10N HCl for 18 min. The lowest concentration of HMF formed (1.8%), at maximal DE of 61%, was established in samples containing 5% SPP and heated at 154/degree/C in 0.034N HCl for 48 min. Aqueous extracts of uncured SPP, examined by High Performance Liquid Chromatography, contained glucose, fructose and sucrose, but degraded SPP had only glucose and fructose. Products of degraded SPP, Under appropriate conditions, could be used for alcohol fermentation. 18 refs.

Synthesis, characterization, and catalytic activity of Rh-based lanthanum zirconate pyrochlores for higher alcohol synthesis  

SciTech Connect (OSTI)

Two lanthanum zirconate pyrochlores (La{sub 2}Zr{sub 2}O{sub 7}; LZ) were prepared by Pechini method and tested for higher alcohols selectivity. In one, Rh was substituted into the pyrochlore lattice (LRZ, 1.7 wt%) while for the second, Rh was supported on an unsubstituted La{sub 2}Zr{sub 2}O{sub 7} (R/LZ, 1.8 wt%). X-ray photoelectron spectroscopy (XPS) and temperature programmed reduction (TPR) results show that the surface reducibility depends on whether the Rh is in (or supported on) the LZ pyrochlore. Rhodium in the LRZ is more reducible than rhodium supported on the R/LZ pyrochlore, likely due to the presence of a perovskite phase (LaRhO{sub 3}; identified by XRD), in which rhodium is more reducible. The formation of the perovskite accompanies that of the pyrochlore. CO hydrogenation results show higher ethanol selectivity for R/LZ than LRZ, possibly due to the strong interaction between Rh and LZ on the R/LZ, forming atomically close Rh{sup +}/Rh{sup 0} sites, which have been suggested to favor ethanol production.

Investigation of electrochemical properties of a poly(vinyl alcohol)/poly(acrylic acid) polymer blend  

SciTech Connect (OSTI)

Chemical sensors have wide applications in medicine, environmental monitoring, industrial applications, and others because of their versatility, ruggedness, sensitivity, selectivity, and economy. Electrochemical sensors are constructed by using a conducting medium, in this case graphite, and applying a constant potential while measuring changes in the current. Polymers are used for electrochemical sensors to exclude interferents from the electrode surface, to preconcentrate the analyte near the electrode, and in some cases to provide a matrix for the immobilization of analytes, such as enzymes. These functions of the polymer can serve to improve the detection limit of the sensor. This project involves the evaluation of a new polymer for electrode modification. The poly(vinyl alcohol)/poly(acrylic acid) (PVA/PAA) polymer was originally developed as an ion exchanger for use in space batteries. It has also been used in wastewater cleanup because it will concentrate heavy metals in the presence of calcium ion. This polymer is also optically clear, so it can potentially be used for an optical sensor. We are interested in investigating the ion exchange properties of the PVA/PAA polymer, as well as the ability of this polymer to preconcentrate and exclude analytes on the basis of size, charge, and hydrophilic/hydrophobic interactions.

Novel Characterization of GDI Engine Exhaust for Gasoline and Mid-Level Gasoline-Alcohol Blends  

SciTech Connect (OSTI)

Gasoline direct injection (GDI) engines can offer improved fuel economy and higher performance over their port fuel-injected (PFI) counterparts, and are now appearing in increasingly more U.S. and European vehicles. Small displacement, turbocharged GDI engines are replacing large displacement engines, particularly in light-duty trucks and sport utility vehicles, in order for manufacturers to meet more stringent fuel economy standards. GDI engines typically emit the most particulate matter (PM) during periods of rich operation such as start-up and acceleration, and emissions of air toxics are also more likely during this condition. A 2.0 L GDI engine was operated at lambda of 0.91 at typical loads for acceleration (2600 rpm, 8 bar BMEP) on three different fuels; an 87 anti-knock index (AKI) gasoline (E0), 30% ethanol blended with the 87 AKI fuel (E30), and 48% isobutanol blended with the 87 AKI fuel. E30 was chosen to maximize octane enhancement while minimizing ethanol-blend level and iBu48 was chosen to match the same fuel oxygen level as E30. Particle size and number, organic carbon and elemental carbon (OC/EC), soot HC speciation, and aldehydes and ketones were all analyzed during the experiment. A new method for soot HC speciation is introduced using a direct, thermal desorption/pyrolysis inlet for the gas chromatograph (GC). Results showed high levels of aromatic compounds were present in the PM, including downstream of the catalyst, and the aldehydes were dominated by the alcohol blending.

Nonlinear optical properties of ZnO/poly (vinyl alcohol) nanocomposite films  

SciTech Connect (OSTI)

Extensive studies have already been reported on the optical characteristics of ZnO/polymer nanocomposite films, using a variety of polymers including transparent polymers such as polystyrene, polymethyl methacrylate etc and many interesting results have been established regarding the non linear optical characteristics of these systems. Poly (vinyl alcohol)(PVA) is a water soluble polymer. Though the structural and optical studies of ZnO/PVA nanocomposite films have already been investigated, there are no detailed reports on the nonlinear optical characteristics of ZnO/PVA nanocomposite films, irrespective of the fact that these nanocomposite films can be synthesized using quite easy and cost effective methods. The present work is an attempt to study in detail the nonlinear optical behaviour of ZnO/PVA nanocomposite films using Z-scan technique. Highly transparent ZnO/PVA nanocomposite films were prepared from the ZnO incorporated PVA solution in water using spin coating technique. The ZnO nanoparticles were synthesized by the simple chemical route at room temperature. High-resolution transmission electron microscopy studies show that the ZnO nanoparticles are of size around 10 nm. The ZnO/PVA nanocomposite films were structurally characterized by X-ray diffraction technique, from which the presence of both PVA and ZnO in the nanocomposite was established. The optical absorptive nonlinearity in the nanocomposite films was investigated using open aperture Z-scan technique. The results indicate optical limiting type nonlinearity in the films due to two photon absorption in ZnO with efficiency more than 50%. These films also show a self defocusing type negative nonlinear refraction in closed aperture Z-scan experiment. The present studies indicate that, highly transparent and homogeneous films of ZnO/PVA nanocomposite can be obtained on glass substrates using simple methods, in a highly cost effective way, since PVA is water soluble. These nanocomposite films offer prospects of application as efficient optical limiters to protect light sensitive devices from the possible damage on exposure to high intensity radiation.

Thermal Decomposition of Bulk K-CoMoSx Mixed Alcohol Catalyst Precursors and Effects on Catalyst Morphology and Performance  

SciTech Connect (OSTI)

Cobalt molybdenum sulfide-type mixed alcohol catalysts were synthesized via calcination of precipitated bulk sulfides and studied with temperature programmed decomposition analysis. Precursors containing aqueous potassium were also considered. Precipitates thermally decomposed in unique events which released ammonia, carbon dioxide, and sulfur. Higher temperature treatments led to more crystalline and less active catalysts in general with ethanol productivity falling from 203 to 97 g (kg cat){sup -1} h{sup -1} when the calcination temperature was increased from 375 to 500 C. The addition of potassium to the precursor led to materials with crystalline potassium sulfides and good catalytic performance. In general, less potassium was required to promote alcohol selectivity when added before calcination. At calcination temperatures above 350 C, segregated cobalt sulfides were observed, suggesting that thermally decomposed sulfide precursors may contain a mixture of molybdenum and cobalt sulfides instead of a dispersed CoMoS type of material. When dimethyl disulfide was fed to the precursor during calcination, crystalline cobalt sulfides were not detected, suggesting an important role of free sulfur during decomposition.

Lignin removal and benzene–alcohol extraction effects on lignin measurements of the hydrothermal pretreated bamboo substrate  

Science Journals Connector (OSTI)

Abstract Lignin content of hydrothermal pretreated bamboo chips was determined by the two methods: TAPPI standard method (222om-06) and TAPPI standard method without benzene–alcohol extraction (BAE). The results showed that including BAE resulted in lower Klason lignin (KL) and acid soluble lignin (ASL) measurements in the prehydrolyzed substrate, that is to say, BAE removed parts of KL and ASL. Therefore, the TAPPI standard method should be modified by omitting the BAE for lignin measurements of pretreated substrate. The following lignin removal analysis suggested that lignin was removed from the bamboo substrate during pretreatment by a combination of degradation reaction and deconstruction; thereafter the pseudo lignin generated in the hydrothermal pretreatment and condensation reaction between the lignin fragments accounted for the later KL increase.

SciTech Connect (OSTI)

The work described is concerned with the significant changes in these mechanisms in the glass-transition range. Permeability, diffusion, and solubility coefficients for CH/sub 4/, C/sub 2/H/sub 4/, C/sub 2/H/sub 6/, and n-C/sub 4/H/sub 10/ in poly(n-butyl methacrylate) (PnBMA) were determined at pressures up to 25 atm and from -14/sup 0/ to 50/sup 0/C. Solubility was also determined for CO/sub 2/ in PnBMA at pressures up to 25 atm and at -10/sup 0/ and 30/sup 0/C. No significant changes were observed in the pressure (or concentration) and temperature dependence of the permeability, diffusion, and solubility coefficients for CH/sub 4/, C/sub 2/H/sub 6/, and n-C/sub 4/H/sub 10/ in the glass-transition range of PnBMA, or when the temperature was lowered below T/sub g/. Moreover, these gas/polymer systems do not exhibit below T/sub g/ the usual ''dual-mode'' sorption behavior of gases in glassy polymers. The solubility isotherm for CO/sub 2/ in PnBMA at -10/sup 0/C and lower pressures suggests incipient dual-mode sorption. Results are exceptions to dual-mode sorption behavior and may be due to small difference in the coefficients of thermal expansion of PnBMA above and below T/sub g/. This indicates that the unrelaxed domains in glassy PnBMA are very small. A ''free-volume'' mechanism describes the dependence of C/sub 2/H/sub 6/ permeability on P, T both above and below the glass transition of PnBMA. Adsorption/desorption kinetics are Fickian.

Conversion of starch to ethanol in a recombinant saccharomyces cerevisiae strain expressing rice [alpha]-amylase from a novel Pichia pastoris alcohol oxidase promoter  

SciTech Connect (OSTI)

A recombinant Saccharomyces cerevisiae, expressing and secreting rice [alpha]-amylase, converts starch to ethanol. The rice [alpha]-amylase gene (OS103) was placed under the transcriptional control of the promoter from a newly described Pichia pastoris alcohol oxidase genomic clone. The nucleotide sequences of ZZA1 and other methanol-regulated promoters were analyzed. A highly conserved sequence (TTG-N[sub 3]-GCTTCCAA-N[sub 5]-TGGT) was found in the 5' flanking regions of alcohol oxidase, methanol oxidase, and dihydroxyacetone synthase genes in Pichia pastoris, Hansenula polymorpha, and Candida biodinii S2.

Alkali/TX sub 2 catalysts for CO/H sub 2 conversion to C sub 1 -C sub 4 alcohols  

SciTech Connect (OSTI)

The objective of this research is to investigate and develop novel catalysts for the conversion of coal-derived synthesis gas into C{sub 1}--C{sub 4} alcohols by a highly selective process. Therefore, the variations of catalyst activity and selectivity for the synthesis of alcohols from H{sub 2}/CO {le}1 synthesis gas for a series of A/TX{sub 2} compounds, where A is a surface alkali dopant, T is a transition metal, and X is a S, Se, or Te, will be determined. The alkali component A, which is essential for C-O and C-C bond forming reactions leading to alcohols, will be highly dispersed on the TX{sub 2} surfaces by using chemical vapor deposition (CVD) and chemical complexation/anchoring (CCA) methods. Catalysts that have been prepared during this quarter include RuS{sub 2}, NbS{sub 2}, K/MoS{sub 2}, and K/Crown either/MoS{sub 2}. Catalysts tested include KOH/MoS{sub 2} and K/Crown ether/MoS{sub 2}. 9 refs., 10 figs., 2 tabs.

Poly(vinyl alcohol) gel sublayers for reverse osmosis membranes. I. Insolubilization by acid-catalyzed dehydration  

SciTech Connect (OSTI)

Both flat-sheet and tubular composite reverse osmosis (RO) membranes were prepared by depositing aqueous solutions of poly(vinyl alcohol) (PVA) and a dehydration catalyst on asymmetric poly(arylether sulfone) (PES) substrate membranes. The PVA coatings were insolubilized by heat treatment to create stable hydrophilic gel-layer membranes. The influence of variables such as PVA concentration, catalyst concentration, curing time, and curing temperature was investigated. It was shown that a simple manipulation of one or two variables could lead to membranes with widely differing salt retention and water permeability characteristics. The insolubilized PVA coatings were intended to serve as hydrophilic gel sublayers on which ultra thin salt-retention barriers could ultimately be formed by interfacial polycondensation. For this purpose, high-flux gel layers were required, whereas salt-retention capabilities were not regarded as important. However, the promising salt retentions obtained as 2 MPa (up to 85% NaCl retention and 92% MgSO[sub 4] retention) showed that some of these PES-PVA composite membranes could function as medium-retention, medium-flux RO membranes, even in the absence of an interfacially formed salt-retention barrier.

Acute and chronic ethanol exposure differentially alters alcohol dehydrogenase and aldehyde dehydrogenase activity in the zebrafish liver  

Science Journals Connector (OSTI)

Abstract Chronic ethanol exposure paradigms have been successfully used in the past to induce behavioral and central nervous system related changes in zebrafish. However, it is currently unknown whether chronic ethanol exposure alters ethanol metabolism in adult zebrafish. In the current study we examine the effect of acute ethanol exposure on adult zebrafish behavioral responses, as well as alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity in the liver. We then examine how two different chronic ethanol exposure paradigms (continuous and repeated ethanol exposure) alter behavioral responses and liver enzyme activity during a subsequent acute ethanol challenge. Acute ethanol exposure increased locomotor activity in a dose-dependent manner. ADH activity was shown to exhibit an inverted U-shaped curve and ALDH activity was decreased by ethanol exposure at all doses. During the acute ethanol challenge, animals that were continuously housed in ethanol exhibited a significantly reduced locomotor response and increased ADH activity, however, ALDH activity did not change. Zebrafish that were repeatedly exposed to ethanol demonstrated a small but significant attenuation of the locomotor response during the acute ethanol challenge but ADH and ALDH activity was similar to controls. Overall, we identified two different chronic ethanol exposure paradigms that differentially alter behavioral and physiological responses in zebrafish. We speculate that these two paradigms may allow dissociation of central nervous system-related and liver enzyme-dependent ethanol induced changes in zebrafish.

Non-phosphate degradation products of tributyl phosphate  

SciTech Connect (OSTI)

Tributyl phosphate(TBP) was compulsively degraded with nitric acid and/or uranium nitrate at elevated temperature around 105{degrees}C. Experimental results indicates major non-phosphate degradation products are butyl nitrate (C{sub 4}H{sub 9}NO{sub 3}), propionic acid (C{sub 2}H{sub 5}COOH), acetic acid (CH{sub 3}COOH), butyric acid (C{sub 3}H{sub 7}COOH) and butyl alcohol (C{sub 4}H{sub 9}OH) in ascending order of quantity. Degrading rate in uranium free system is less than that in uranium coexisting system. Carboxylic acids were not produced in uranium free system, and only acetic acid was identified in case of without supplying nitric acid from aqueous phase. Moreover, from the experimental study on the reactivity of each non-phosphate product with nitric acid, carboxylic acids were identified as byproducts of butyl alcohol and butyl nitrate, and each carboxylic acid was stable in these degrading conditions. Finally, butyl alcohol is considered as one of intermediate products to butyl nitrate and carboxylic acids. From this study, the non-phosphate degradation products of TBP is identified and the degrading reaction pass is proposed. Extraction behavior of each non-phosphate product and reactivity of degraded TBP are also elucidated.

Deep eutectic solvents (DES) as green reaction media for the redox isomerization of allylic alcohols into carbonyl compounds catalyzed by the ruthenium complex [Ru(?3:?3-C10H16)Cl2(benzimidazole)  

Science Journals Connector (OSTI)

Abstract The bis-allyl Ru(IV) complex [Ru(?3:?3-C10H16)Cl2(benzimidazole)] (1c) is an active catalyst in the redox isomerization of allylic alcohols into saturated carbonyl compounds using, for the first time, Deep eutectic solvents (DES) as reaction media. A series of primary and secondary allylic alcohols could be isomerized into the corresponding carbonyl compounds in the absence of base. Although high activities and selectivities were reached at short reaction times and with low catalyst loadings (0.2 mol% in Ru) for monosubstituted allylic alcohols, for their disubstituted counterparts, high catalyst loading and longer reaction times were always required. It is important to note that the catalytic system: i) is active in a large-scale experiment, and ii) could be recycled up to four consecutive runs.

Production of hydrogen rich bio-oil derived syngas from co-gasification of bio-oil and waste engine oil as feedstock for lower alcohols synthesis in two-stage bed reactor  

Science Journals Connector (OSTI)

Abstract High efficient production of lower alcohols (C1–C5 mixed alcohols) from hydrogen rich bio-oil derived syngas was achieved in this work. A non-catalytic partial oxidation (NPOX) gasification technology was successfully applied in the production and conditioning of bio-oil derived syngas using bio-oil (BO) and emulsifying waste engine oil (EWEO) as feedstock. The effects of water addition and feedstock composition on the gasification performances were investigated. When the BO20 and EWEO30 was mixed with mass ratio of 1: 0.33, the maximum hydrogen yield of 93.7% with carbon conversion of 96.7% was obtained, and the hydrogen rich bio-oil derived syngas was effectively produced. Furthermore, a two-stage bed reactor was applied in the downstream process of lower alcohols synthesis from hydrogen rich bio-oil derived syngas (H2/CO/CO2/CH4/N2 = 52.2/19.5/3.0/9.4/15.9, v/v). The highest carbon conversion of 42.5% and the maximum alcohol yield of 0.18 kg/kgcat h with selectivity of 53.8 wt% were obtained over the Cu/ZnO/Al2O3(2.5)//Cu25Fe22Co3K3/SiO2(2.5) catalyst combination system. The mechanism and evaluation for lower alcohols synthesis from model bio-oil derived syngas and model mixture gas were also discussed. The integrative process of hydrogen rich bio-oil derived syngas production and downstream lower alcohols synthesis, potentially providing a promising route for the conversion of organic wastes into high performance fuels and high value-added chemicals.

Genetic improvement of Escherichia coli for ethanol production: Chromosomal integration of Zymomonas mobilis genes encoding pyruvate decarboxylase and alcohol dehydrogenase II  

SciTech Connect (OSTI)

Zymomonas mobilis genes for pyruvate decarboxylase (pdc) and alcohol dehydrogenase II (adhB) were integrated into the Escherichia coli chromosome within or near the pyruvate formate-lyase gene (pfl). Integration improved the stability of the Z. mobilis genes in E. coli, but further selection was required to increase expression. Spontaneous mutants were selected for resistance to high levels of chloramphenicol that also expressed high levels of the Z. mobilis genes. Analogous mutants were selected for increased expression of alcohol dehydrogenase on aldehyde indicator plates. These mutants were functionally equivalent to the previous plasmid-based strains for the fermentation of xylose and glucose to ethanol. Ethanol concentrations of 54.4 and 41.6 g/liter were obtained from 10% glucose and 8% xylose, respectively. The efficiency of conversion exceeded theoretical limits (0.51 g of ethanol/g of sugar) on the basis of added sugars because of the additional production of ethanol from the catabolism of complex nutrients. Further mutations were introduced to inactivate succinate production (frd) and to block homologous recombination (recA).

Municipal Solid Waste (MSW) to Liquid Fuels Synthesis, Volume 2: A Techno-economic Evaluation of the Production of Mixed Alcohols  

SciTech Connect (OSTI)

Biomass is a renewable energy resource that can be converted into liquid fuel suitable for transportation applications and thus help meet the Energy Independence and Security Act renewable energy goals (U.S. Congress 2007). However, biomass is not always available in sufficient quantity at a price compatible with fuels production. Municipal solid waste (MSW) on the other hand is readily available in large quantities in some communities and is considered a partially renewable feedstock. Furthermore, MSW may be available for little or no cost. This report provides a techno-economic analysis of the production of mixed alcohols from MSW and compares it to the costs for a wood based plant. In this analysis, MSW is processed into refuse derived fuel (RDF) and then gasified in a plant co-located with a landfill. The resulting syngas is then catalytically converted to mixed alcohols. At a scale of 2000 metric tons per day of RDF, and using current technology, the minimum ethanol selling price at a 10% rate of return is approximately $1.85/gallon ethanol (early 2008 $). However, favorable economics are dependent upon the toxicity characteristics of the waste streams and that a market exists for the by-product scrap metal recovered from the RDF process.

Results of the feasibility studies awarded under PL 96-126 and PL 96-304 for alcohol fuel production. Final report  

SciTech Connect (OSTI)

The results from the feasibility study grants are summarized. The grants were to allow assessment of the technical and economic feasibility of construction and operation of commercial-scale alcohol fuel production facilities. Summarized are the process designs, financial and economic analyses, marketing analyses, and the environmental assessments. Use of current technology was declared to be adequate; no patents evolved from the studies. Suitable sites, served by transportation and utilities were located. Feedstock, energy sources, and raw materials were determined to be available. Environmental guidelines were found to be attainable and socioeconomic impacts and public acceptance of the projects were reported. Most of the proposed plants were declared to be economically feasible with profitability increasing with plant size. Financing was reported constrained by premium interest rates, an insecure ethanol market, and financial institution requirements for loan guarantees or high-equality loans.

Influences of alcoholic solvents on spray pyrolysis deposition of TiO{sub 2} blocking layer films for solid-state dye-sensitized solar cells  

SciTech Connect (OSTI)

Influences of alcoholic solvents for titanium diisopropoxide bis(acetylacetonate) (TPA) precursor solutions on the spray pyrolysis deposited TiO{sub 2} films and the photovoltaic performance of the solid-state dye-sensitized solar cells (SDSCs) using these TiO{sub 2} films as the blocking layers were investigated. Smooth TiO{sub 2} films were obtained by spray pyrolysis deposition of a TPA solution in isopropanol (IPA) at a relatively low temperature of 260 Degree-Sign C. On the other hand, when ethanol was used as solvent, the TiO{sub 2} films fabricated at the same temperature showed much rougher surfaces with many pinholes. Our results showed that ethanol reacts with TPA to form titanium diethoxide bis(acetylacetonate) (TEA), which requires a higher thermal decomposition temperature than that of TPA. SDSCs with TiO{sub 2} blocking layer films fabricated using a TPA solution in IPA showed higher power conversion efficiencies with smaller variations. - Graphical abstract: Alcoholic solvents used for the TiO{sub 2} precursor play a critical role in determining the surface morphology of blocking layers and thus the photovoltaic performance of the SDSCs. Highlights: Black-Right-Pointing-Pointer Solvent influences morphology of spray pyrolysis deposited TiO{sub 2} blocking layer. Black-Right-Pointing-Pointer Ethanol reacts with TPA, resulting poor quality of blocking layer. Black-Right-Pointing-Pointer Isopropanol is better than ethanol for obtaining smooth blocking layer. Black-Right-Pointing-Pointer SDSC with blocking layer made with isopropanol showed better performance.

Transition metal complexes of oxazolinylboranes and cyclopentadienyl-bis(oxazolinyl)borates: Catalysts for asymmetric olefin hydroamination and acceptorless alcohol decarbonylation  

SciTech Connect (OSTI)

The research presented and discussed in this dissertation involves the synthesis of transition metal complexes of oxazolinylboranes and cyclopentadienyl-bis(oxazolinyl)borates, and their application in catalytic enantioselective olefin hydroamination and acceptorless alcohol decarbonylation. Neutral oxazolinylboranes are excellent synthetic intermediates for preparing new borate ligands and also developing organometallic complexes. Achiral and optically active bis(oxazolinyl)phenylboranes are synthesized by reaction of 2-lithio-2-oxazolide and 0.50 equiv of dichlorophenylborane. These bis(oxazolinyl)phenylboranes are oligomeric species in solid state resulting from the coordination of an oxazoline to the boron center of another borane monomer. The treatment of chiral bis(oxazolinyl)phenylboranes with sodium cyclopentadienide provide optically active cyclopentadienyl-bis(oxazolinyl)borates H[PhB(C{sub 5}H{sub 5})(Ox{sup R}){sub 2}] [Ox{sup R} = Ox{sup 4S-iPr,Me2}, Ox{sup 4R-iPr,Me2}, Ox{sup 4S-tBu]}. These optically active proligands react with an equivalent of M(NMe{sub 2}){sub 4} (M = Ti, Zr, Hf) to afford corresponding cyclopentadienyl-bis(oxazolinyl)borato group 4 complexes {PhB(C{sub 5}H{sub 4})(Ox{sup R}){sub 2}}M(NMe{sub 2}){sub 2} in high yields. These group 4 compounds catalyze cyclization of aminoalkenes at room temperature or below, providing pyrrolidine, piperidine, and azepane with enantiomeric excesses up to 99%. Our mechanistic investigations suggest a non-insertive mechanism involving concerted C?N/C?H bond formation in the turnover limiting step of the catalytic cycle. Among cyclopentadienyl-bis(oxazolinyl)borato group 4 catalysts, the zirconium complex {PhB(C{sub 5}H{sub 4})(Ox{sup 4S-iPr,Me2}){sub 2}}Zr(NMe{sub 2}){sub 2} ({S-2}Zr(NMe{sub 2}){sub 2}) displays highest activity and enantioselectivity. Interestingly, {S-2}Zr(NMe{sub 2}){sub 2} also desymmetrizes olefin moieties of achiral non-conjugated aminodienes and aminodiynes during cyclization. The cyclization of aminodienes catalyzed by {S-2}Zr(NMe{sub 2}){sub 2} affords diastereomeric mixture of cis and trans cylic amines with high diasteromeric ratios and excellent enantiomeric excesses. Similarly, the desymmetrization of alkyne moieties in {S-2}Zr(NMe{sub 2}){sub 2}-catalyzed cyclization of aminodiynes provides corresponding cyclic imines bearing quaternary stereocenters with enantiomeric excesses up to 93%. These stereoselective desymmetrization reactions are significantly affected by concentration of the substrate, temperature, and the presence of a noncyclizable primary amine. In addition, both the diastereomeric ratios and enantiomeric excesses of the products are markedly enhanced by N-deuteration of the substrates. Notably, the cationic zirconium-monoamide complex [{S-2}Zr(NMe{sub 2})][B(C{sub 6}F{sub 5}){sub 4}] obtained from neutral {S-2}Zr(NMe{sub 2}){sub 2} cyclizes primary aminopentenes providing pyrrolidines with S-configuration; whereas {S-2}Zr(NMe{sub 2}){sub 2} provides R-configured pyrrolidines. The yttrium complex {S-2}YCH{sub 2}SiMe{sub 3} also affords S-configured pyrrolidines by cyclization of aminopentenes, however the enantiomeric excesses of products are low. An alternative optically active yttrium complex {PhB(C{sub 5}H{sub 4})(Ox{sup 4S-tBu}){sub 2}}YCH{sub 2}SiMe{sub 3} ({S-3}YCH{sub 2}SiMe{sub 3}) is synthesized, which displays highly enantioselective in the cyclization of aminoalkenes at room temperature affording S-configured cyclic amines with enantiomeric excesses up to 96%. A noninsertive mechanism involving a six-membered transition state by a concerted C?N bond formation and N?H bond cleavage is proposed for {S-3}YCH{sub 2}SiMe{sub 3} system based on the kinetic, spectroscopic, and stereochemical features. In the end, a series of bis- and tris(oxazolinyl)borato iridium and rhodium complexes are synthesized with bis(oxazolinyl)phenylborane [PhB(Ox{sup Me2}){sub 2}]{sub n}, tris(oxazolinyl)borane [B(Ox{sup Me2}){sub 3}]n, and tris(4,4-dimethyl-2-oxazolinyl)phenylborate [To{sup M}]{sup ?}.

Chemical transformations during rectification of products of hydroformylation of propylene  

SciTech Connect (OSTI)

The occurrence of reactions related to losses of the target products, aldehydes and alcohols, was established in continuous rectification of the products of hydroformylation of propylene. The sections of the zone of primary occurrence of the reactions of aldol condensation, formation of acetals, and esterification of butyl alcohols with butyric acids were determined in the rectification column. It was shown that with increase in temperature in the rectification column still the degree of aldehyde and alcohol conversion in the overall rectification system decreases with respect to aldol condensation and acetal formation, while increasing with respect to alcohol esterification.

Dehydration of isobutanol to isobutene in a slurry reactor  

SciTech Connect (OSTI)

The April 1990 Alternative Fuels Proposal to the Department of Energy involved the development of new technology, based on the liquid phase process, for conversion of coal-derived synthesis gas to oxygenated hydrocarbon fuels, fuel additives, and fuel intermediates. The objective of this work was to develop a slurry reactor based process for the dehydration of isobutanol to isobutene. The isobutene can serve as a feedstock for the high octane oxygenated fuel additive methyl tertiary-butyl either (MTBE). Alumina catalysts were investigated because of their wide use as a dehydration catalyst. Four commercially available alumina catalysts (Catapal B, Versal B, Versal GH, and Al-3996R) were evaluated for both activity and selectivity to the branched olefin. All four catalysts demonstrated conversions greater than 80% at 290 C, while conversions of near 100% could be obtained at 330 C. The reaction favors low pressures and moderate to low space velocities. A yield of 0.90 mole isobutene per mole reacted isobutanol or better was obtained at conversions of 60--70% and higher. From 75 to 98% conversion, the four catalysts all provide isobutene yields ranging from 0.92 to 0.94 with the maximum occurring around 90% conversion. At low conversions, the concentration of diisobutyl ether becomes significant while the concentration of linear butenes is essentially a linear function of isobutanol conversion. Doping the catalyst with up to 0.8 wt % potassium showed a modest increase in isobutene selectivity; however, this increase was more than offset by a reduction in activity. Investigations using a mixed alcohols feed (consistent with isobutanol synthesis from syngas) demonstrated a small increase in the C4 iso-olefin selectivity over that observed for a pure isobutanol feed. 55 refs.

Basic study for the application of Cu supported ZnS and ZnO photocatalysts for the CO{sub 2} conversion into alcohol  

SciTech Connect (OSTI)

Transformation of CO{sub 2} into alcohol by using photocatalysts is one of the “green” methods to solve the environmental problem. In this study, to increase the activity, condition of Cu co-catalysts onto the substrate (Zn photocatalysts) were precisely controlled by obeying to relationship between the surface potential of substrate and the condition of metal complexes in solution by applying the metal complexes calculation using critical stability constants. By obeying to calculation results, Cu metal complexes with positively charged species, [(Cu{sup 2+})(MEA){sub 2}] and [(Cu{sup 2+})(MEA){sub 3}] and/or negatively charged species, [(Cu{sup 2+})(OH{sup ?})(cit{sup 3?})] monomer and dimmer, were stably synthesized. Absorption amount of Cu species was successfully controlled by using these solutions since surface potential of ZnO was negative. When the concentration of Cu in the solution was same, the difference of adsorption amount led the difference of the number of nuclear site of Cu particles. As a result, the size of co-catalysts in the case of MEA became smaller.

Simultaneous liquid–liquid and vapour–liquid equilibria predictions of selected oxygenated aromatic molecules in mixtures with alkanes, alcohols, water, using the polar GC-PC-SAFT  

Science Journals Connector (OSTI)

Abstract Phase equilibria of oxygen-bearing aromatic compounds, hydrocarbons and water mixtures are of essential interest in many processes using feeds originating from biomass. The strong non-ideal thermodynamic behavior of these systems sometimes results in immiscibility with both water and alkanes. To address this problem, the GC-PPC-SAFT equation of state [Tamouza et al., 2004; Nguyen-Huynh et al., 2008a] is extended to some selected components: phenol, alkyl-phenols, alkyl-benzoates, benzaldehyde and anisole. However, as in these multifunctional compounds, the proximity of polar functional groups may result in a lack of transferability of the parameters from the monofunctional homologous species, some parameters have been adapted in view of physical arguments. Next, liquid–vapour and liquid–liquid equilibria of mixtures with n-alkanes were evaluated, using a predictive method for the binary interaction parameters (kij) [Nguyen-Huynh et al., 2008b]. Finally, mixtures with other associating compounds, as alcohols and water have also been considered. In all cases, both correlations and predictions are qualitatively and quantitatively satisfactory. The relative deviations obtained on bubble pressure of vapor–liquid equilibria are 4–8%, that is comparable to those obtained on previously investigated systems.

Pool octanes via oxygenates  

SciTech Connect (OSTI)

Increasingly stringent antipollution regulations placed on automobile exhaust gases with consequent reduction or complete lead ban from motor gasoline result in octane shortage at many manufacturing sites. Attractive solutions to this problem, especially in conjunction with abundant methanol supplies, are the hydration and etherification of olefins contained in light product streams from cracking unit or produced by field gas dehydrogenation. A comparison is made between oxygenates octane-volume pool contributions and established refinery technologies. Process reviews for bulk manufacture of fuel-grade isopropanol (IPA), secondary butanol (SBA), tertiary butanol (TBA), methyl tertiary butyl ether (MTBE) and tertiary amyl methyl ether (TAME) are presented together with the characteristic investment and operating data. The implantation of these processes into a typical FCCU refinery complex with the resulting octane-pool improvement possibilities is descried.

Safe conditions for contacting nitric acid or nitrates with tri-n-butyl phosphate (TBP)  

SciTech Connect (OSTI)

In response to a request from DOE-SR, the current state of knowledge of the reactions between TBP and aqueous nitrate solutions is critically reviewed, and recommendations are made for the safe operation of SRS separations equipment in which this combination of chemicals may be present. The existing limits for evaporation are validated. Guidelines are presented for cases in which general limits do not apply. The rate of reaction between nitric acid and TBP appears to be controlled by the rate of TBP hydrolysis. The hydrolysis reaction produces dibutyl phosphate and n-butanol. The hydrolysis rate is a strong function of temperature, and becomes very fast at temperatures in the range 130{degrees} to 150{degrees}C. The resulting n-butanol is volatile at high temperatures, boiling at 117.5{degrees}C, but is also subject to exothermic oxidation by nitric acid or nitrates. If oxidation occurs before the n-butanol evaporates, the heat of oxidation may exceed local cooling by convection. The resulting heating will further accelerate the reaction, leading to an energetic runaway and possibly (in confined systems) an explosion. Extensive experiments and practice have shown that in a well-mixed and well-vented aqueous system such as an evaporator, at moderate acidities and temperatures below 130{degrees}C, the heat of reaction is adequately removed by vaporization of steam. In general, the heating will be so slow that natural processes provide adequate cooling at temperatures below 80{degrees}C. Above this temperature, care should be taken to ensure that adequate cooling is available for the amount of TBP that may be present. Experiments suggest that in well-ventilated systems n-butanol evaporation and convective cooling are sufficient to control the reaction at temperatures up to 120{degrees}C.
