Succinic Acid as a Byproduct in a Corn-based Ethanol Biorefinery  

SciTech Connect (OSTI)

MBI endeavored to develop a process for succinic acid production suitable for integration into a corn-based ethanol biorefinery. The project investigated the fermentative production of succinic acid using byproducts of corn mill operations. The fermentation process was attuned to include raw starch, endosperm, as the sugar source. A clean-not-sterile process was established to treat the endosperm and release the monomeric sugars. We developed the fermentation process to utilize a byproduct of corn ethanol fermentations, thin stillage, as the source of complex nitrogen and vitamin components needed to support succinic acid production in A. succinogenes. Further supplementations were eliminated without lowering titers and yields and a productivity above 0.6 g l-1 hr-1was achieved. Strain development was accomplished through generation of a recombinant strain that increased yields of succinic acid production. Isolation of additional strains with improved features was also pursued and frozen stocks were prepared from enriched, characterized cultures. Two recovery processes were evaluated at pilot scale and data obtained was incorporated into our economic analyses.

NREL: Biomass Research - What Is a Biorefinery?  

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

What Is a Biorefinery? What Is a Biorefinery? A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power, and chemicals from biomass. The biorefinery concept is analogous to today's petroleum refineries, which produce multiple fuels and products from petroleum. Industrial biorefineries have been identified as the most promising route to the creation of a new domestic biobased industry. By producing multiple products, a biorefinery can take advantage of the differences in biomass components and intermediates and maximize the value derived from the biomass feedstock. A biorefinery might, for example, produce one or several low-volume, but high-value, chemical products and a low-value, but high-volume liquid transportation fuel, while generating

Improving Energy Efficiency and Enabling Water Recycle in Biorefineries Using Bioelectrochemical Cells.  

SciTech Connect (OSTI)

Improving biofuel yield and water reuse are two important issues in further development of biorefineries. The total energy content of liquid fuels (including ethanol and hydrocarbon) produced from cellulosic biomass via biochemical or hybrid bio-thermochemical routes can vary from 49% to 70% of the biomass entering the biorefinery, on an energy basis. Use of boiler for combustion of residual organics and lignin results in significant energy and water losses. An alternate process to improve energy recovery from the residual organic streams is via use of bioelectrochemical systems such as microbial fuel cells (MFCs) microbial electrolysis cells (MECs). The potential advantages of this alternative scheme in a biorefinery include minimization of heat loss and generation of a higher value product, hydrogen. The need for 5-15 gallons of water per gallon of ethanol can be reduced significantly via recycle of water after MEC treatment. Removal of inhibitory byproducts such as furans, phenolics and acetate in MFC/MECs to generate energy, thus, has dual advantages including improvements in energy efficiency and ability to recycle water. Conversion of the sugar- and lignin- degradation products to hydrogen is synergistic with biorefinery hydrogen requirements for upgrading F-T liquids and other byproducts to high-octane fuels and/or high value products. Some of these products include sorbitol, succinic acid, furan and levulinate derivatives, glycols, polyols, 1,4-butenadiol, phenolics polymers, etc. Potential process alternatives utilizing MECs in biorefineries capable of improving energy efficiency by up to 30% are discussed.

The plant contact information was gathered from the related websites, the exact physical location of the plant was verified, the production and storage capacity at the location, the mode of transportation used to ship ethanol to the marketer and the loading capacity were also obtained from the source. The contact information of the person had also been recorded for future reference. The information obtained had been updated to the geodatabase. Few organizations have been reluctant to share information due to proprietary issues.

Controlling Accumulation of Fermentation Inhibitors in Biorefinery Recycle Water Using Microbial Fuel Cells  

SciTech Connect (OSTI)

Background Microbial fuel cells (MFC) and microbial electrolysis cells are electrical devices that treat water using microorganisms and convert soluble organic matter into electricity and hydrogen, respectively. Emerging cellulosic biorefineries are expected to use large amounts of water during production of ethanol. Pretreatment of cellulosic biomass results in production of fermentation inhibitors which accumulate in process water and make the water recycle process difficult. Use of MFCs to remove the inhibitory sugar and lignin degradation products from recycle water is investigated in this study. Results Use of an MFC to reduce the levels of furfural, 5-hydroxymethylfurfural, vanillic acid, 4- hydroxybenzaldehyde and 4-hydroxyacetophenone while simultaneously producing electricity is demonstrated here. An integrated MFC design approach was used which resulted in high power densities for the MFC, reaching up to 3700mW/m2 (356W/m3 net anode volume) and a coulombic efficiency of 69%. The exoelectrogenic microbial consortium enriched in the anode was characterized using a 16S rRNA clone library method. A unique exoelectrogenic microbial consortium dominated by -Proteobacteria (50%), along with -Proteobacteria (28%), -Proteobacteria (14%), -Proteobacteria (6%) and others was identified. The consortium demonstrated broad substrate specificity, ability to handle high inhibitor concentrations (5 to 20mM) with near complete removal, while maintaining long-term stability with respect to power production. Conclusions Use of MFCs for removing fermentation inhibitors has implications for: 1) enabling higher ethanol yields at high biomass loading in cellulosic ethanol biorefineries, 2) improved water recycle and 3) electricity production up to 25% of total biorefinery power needs.

Estimating Hydrogen Production Potential in Biorefineries Using Microbial Electrolysis Cell Technology  

SciTech Connect (OSTI)

Microbial electrolysis cells (MECs) are devices that use a hybrid biocatalysis-electrolysis process for production of hydrogen from organic matter. Future biofuel and bioproducts industries are expected to generate significant volumes of waste streams containing easily degradable organic matter. The emerging MEC technology has potential to derive added- value from these waste streams via production of hydrogen. Biorefinery process streams, particularly the stillage or distillation bottoms contain underutilized sugars as well as fermentation and pretreatment byproducts. In a lignocellulosic biorefinery designed for producing 70 million gallons of ethanol per year, up to 7200 m3/hr of hydrogen can be generated. The hydrogen can either be used as an energy source or a chemical reagent for upgrading and other reactions. The energy content of the hydrogen generated is sufficient to meet 57% of the distillation energy needs. We also report on the potential for hydrogen production in existing corn mills and sugar-based biorefineries. Removal of the organics from stillage has potential to facilitate water recycle. Pretreatment and fermentation byproducts generated in lignocellulosic biorefinery processes can accumulate to highly inhibitory levels in the process streams, if water is recycled. The byproducts of concern including sugar- and lignin- degradation products such as furans and phenolics can also be converted to hydrogen in MECs. We evaluate hydrogen production from various inhibitory byproducts generated during pretreatment of various types of biomass. Finally, the research needs for development of the MEC technology and aspects particularly relevant to the biorefineries are discussed.

Simulating Pelletization Strategies to Reduce the Biomass Supply Risk at America’s Biorefineries  

SciTech Connect (OSTI)

Demand for cellulosic ethanol and other advanced biofuels has been on the rise, due in part to federal targets enacted in 2005 and extended in 2007. The industry faces major challenges in meeting these worthwhile and ambitious targets. The challenges are especially severe in the logistics of timely feedstock delivery to biorefineries. Logistical difficulties arise from seasonal production that forces the biomass to be stored in uncontrolled field-side environments. In this storage format physical difficulties arise; transportation is hindered by the low bulk density of baled biomass and the unprotected material can decay leading to unpredictable losses. Additionally, uncertain yields and contractual difficulties can exacerbate these challenges making biorefineries a high-risk venture. Investors’ risk could limit business entry and prevent America from reaching the targets. This paper explores pelletizer strategies to convert the lignocellulosic biomass into a denser form more suitable for storage. The densification of biomass would reduce supply risks, and the new system would outperform conventional biorefinery supply systems. Pelletizer strategies exhibit somewhat higher costs, but the reduction in risk is well worth the extra cost if America is to grow the advanced biofuels industry in a sustainable manner.

BIO?REFINERIES: BIOPROCESS TECHNOLOGIES FOR WASTE?WATER TREATMENT, ENERGY AND PRODUCT VALORIZATION  

Science Journals Connector (OSTI)

Increasing pressure is being exerted on communities and nations to source energy from forms other than fossil fuels. Also potable water is becoming a scarce resource in many parts of the world and there remains a large divide in the demand and utilization of plant products derived from genetically modified organisms (GMOs) and non?GMOs. The most extensive user and manager of terrestrial ecosystems is agriculture which is also the de facto steward of natural resources. As stated by Miller (2008) no other industry or institution comes close to the comparative advantage held for this vital responsibility while simultaneously providing food fiber and other biology?based products including energy. Since modern commercial agriculture is transitioning from the production of bulk commodities to the provision of standardized products and specific?attribute raw materials for differentiated markets we can argue that processes such as mass cultivation of microalgae and the concept of bio?refineries be seen as part of a ‘new’ agronomy. EBRU is currently exploring the integration of bioprocess technologies using microalgae as biocatalysts to achieve waste?water treatment water polishing and endocrine disruptor (EDC) removal sustainable energy production and exploitation of the resultant biomass in agriculture as foliar fertilizer and seed coatings and for commercial extraction of bulk commodities such as bio?oils and lecithin. This presentation will address efforts to establish a fully operational solar?driven microalgae bio?refinery for use not only in waste remediation but to transform waste and biomass to energy fuels and other useful materials (valorisation) with particular focus on environmental quality and sustainability goals.

Ethanol production in biorefineries using lignocellulosic feedstock – GHG performance, energy balance and implications of life cycle calculation methodology  

Science Journals Connector (OSTI)

Abstract Co-production of high-value biobased products in biorefineries is a promising option for optimized utilization of biomass. Lignocellulosic materials such as agricultural and forest residues have been identified as attractive alternative feedstocks because of their high availability and low resource demand. This study assessed the greenhouse gas (GHG) performance and energy balance of ethanol co-production with biogas and electricity in biorefineries using straw and forest residues. Two calculation methods were used: Method I (ISO), which applied the international standard for life cycle assessment, and Method II, which applied the EU Renewable Energy Directive (RED) methodology. These methods differed in allocation procedure, functional unit and system boundaries. Analysis of the importance of significant methodological choices and critical parameters showed that the results varied depending on calculation method, with co-product handling and the inclusion of upstream impacts from residue harvesting explaining most of the differences. Important life cycle steps were process inputs in terms of enzymes and changes in soil organic carbon content due to removal of residues. Ethanol produced from forest residues generally gave lower GHG emissions than straw-based ethanol. The GHG savings for both feedstocks were 51–84% relative to fossil fuel. Omission of upstream impacts from residue recovery in agriculture and forestry in the RED method means that it risks overlooking important environmental effects of residue reuse. Furthermore, the default allocation procedure used in the RED method (energy allocation) may need revision for biorefineries where multiple products with different characteristics are co-produced.

Final Technical Report: Improvement of Zymomonas mobilis for Commercial Use in Corn-based Biorefineries  

SciTech Connect (OSTI)

Between 2007 and 2010 DuPont conducted a program under DOE award DE-FC36-07GO17056 to develop and improve Zymomonas mobilis as an ethanologen for commercial use in biorefineries to produce cellulosic ethanol. This program followed upon an earlier DOE funded program in which DuPont, in collaboration with the National Renewable Energy Laboratory (NREL) had developed a Zymomonas strain in conjunction with the development of an integrated cellulosic ethanol process. In the current project, we sought to maximize the utility of Zymomonas by adding the pathway to allow fermentation of the minor sugar arabinose, improve the utilization of xylose, improve tolerance to process hydrolysate and reduce the cost of producing the ethanologen. We undertook four major work streams to address these tasks, employing a range of approaches including genetic engineering, adaptation, metabolite and pathway analysis and fermentation process development. Through this project, we have developed a series of strains with improved characteristics versus the starting strain, and demonstrated robust scalability to at least the 200L scale. By a combination of improved ethanol fermentation yield and titer as well as reduced seed train costs, we have been able to reduce the capital investment and minimum ethanol selling price (MESP) by approximately 8.5% and 11% respectively vs. our starting point. Furthermore, the new strains we have developed, coupled with the learnings of this program, provide a platform for further strain improvements and advancement of cellulosic ethanol technology.

Investigation of thermochemical biorefinery sizing and environmental sustainability impacts for conventional supply system and distributed pre-processing supply system designs  

SciTech Connect (OSTI)

The 2011 US Billion-Ton Update estimates that by 2030 there will be enough agricultural and forest resources to sustainably provide at least one billion dry tons of biomass annually, enough to displace approximately 30% of the country's current petroleum consumption. A portion of these resources are inaccessible at current cost targets with conventional feedstock supply systems because of their remoteness or low yields. Reliable analyses and projections of US biofuels production depend on assumptions about the supply system and biorefinery capacity, which, in turn, depend upon economic value, feedstock logistics, and sustainability. A cross-functional team has examined combinations of advances in feedstock supply systems and biorefinery capacities with rigorous design information, improved crop yield and agronomic practices, and improved estimates of sustainable biomass availability. A previous report on biochemical refinery capacity noted that under advanced feedstock logistic supply systems that include depots and pre-processing operations there are cost advantages that support larger biorefineries up to 10 000 DMT/day facilities compared to the smaller 2000 DMT/day facilities. This report focuses on analyzing conventional versus advanced depot biomass supply systems for a thermochemical conversion and refinery sizing based on woody biomass. The results of this analysis demonstrate that the economies of scale enabled by advanced logistics offsets much of the added logistics costs from additional depot processing and transportation, resulting in a small overall increase to the minimum ethanol selling price compared to the conventional logistic supply system. While the overall costs do increase slightly for the advanced logistic supply systems, the ability to mitigate moisture and ash in the system will improve the storage and conversion processes. In addition, being able to draw on feedstocks from further distances will decrease the risk of biomass supply to the conversion facility.

Green ultrasound-assisted extraction of carotenoids based on the bio-refinery concept using sunflower oil as an alternative solvent  

Science Journals Connector (OSTI)

A green, inexpensive and easy-to-use method for carotenoids extraction from fresh carrots assisted by ultrasound was designed in this work. Sunflower oil was applied as a substitute to organic solvents in this green ultrasound-assisted extraction (UAE): a process which is in line with green extraction and bio-refinery concepts. The processing procedure of this original UAE was first compared with conventional solvent extraction (CSE) using hexane as solvent. Moreover, the UAE optimal conditions for the subsequent comparison were optimized using response surface methodology (RSM) and ultra performance liquid chromatography – diode array detector – mass spectroscopy (UPLC–DAD–MS). The results showed that the UAE using sunflower as solvent has obtained its highest ?-carotene yield (334.75 mg/l) in 20 min only, while CSE using hexane as solvent obtained a similar yield (321.35 mg/l) in 60 min. The green UAE performed under optimal extraction conditions (carrot to oil ratio of 2:10, ultrasonic intensity of 22.5 W cm?2, temperature of 40 °C and sonication time of 20 min) gave the best yield of ?-carotene.

Combined Dilute Acid and Solvent Based Pretreatment of Agricultural Wastes for Efficient Lignocellulosic Fractionation and Biofuels Production  

SciTech Connect (OSTI)

A true biorefinery for processing lignocellulosic biomass should achieve maximum utilization of all major constituents (cellulose, hemicellulose, & lignin) within the feedstock. In this work a combined pretreatment process of dilute acid (DA) and N-methyl morpholine N-oxide (NMMO) is described that allows for both fractionation and subsequent complete hydrolysis of the feedstocks (corn stover and sugarcane bagasse). During this multi-step processing, the dilute acid pretreatment solubilizes the majority (>90%) of the hemicellulosic fraction, while the NMMO treatment yields a cellulosic fraction that is completely digestible within 48 hours at low enzyme loadings. With both the cellulosic and hemicellulosic fractions being converted into separate, dissolved sugar fractions, the remaining portion is nearly pure lignin. When used independently, DA and NMMO pretreatments are only able to achieve ~80% and ~45% cellulosic conversion, respectively. Mass balance calculations along with experimental results are used to illustrate the feasibility of separation and recycling of NMMO.

Process Design and Economics for Biochemical Conversion of Lignocellulosic Biomass to Ethanol: Dilute-Acid Pretreatment and Enzymatic Hydrolysis of Corn Stover  

Broader source: Energy.gov [DOE]

This report describes one potential biochemical ethanol conversion process, conceptually based upon core conversion and process integration research at NREL. The overarching process design converts corn stover to ethanol by dilute-acid pretreatment, enzymatic saccharification, and co-fermentation. Building on design reports published in 2002 and 1999, NREL, together with the subcontractor Harris Group Inc., performed a complete review of the process design and economic model for the biomass-to-ethanol process. This update reflects NREL's current vision of the biochemical ethanol process and includes the latest research in the conversion areas (pretreatment, conditioning, saccharification, and fermentation), optimizations in product recovery, and our latest understanding of the ethanol plant's back end (wastewater and utilities). The conceptual design presented here reports ethanol production economics as determined by 2012 conversion targets and 'nth-plant' project costs and financing. For the biorefinery described here, processing 2,205 dry ton/day at 76% theoretical ethanol yield (79 gal/dry ton), the ethanol selling price is $2.15/gal in 2007$.

Chlorophyll and acid rain Chlorophyll and acid rain Name: beachbum Status: N/A Age: N/A Location: N/A Country: N/A Date: Around 1993 Question: A while ago I read an article that stated that after a plant received acid rain, there seemed to be less of chlorophyll a and b in the plant. I was wondering where does the chlorophyll go and what is the actual process (cell structure affected?). Replies: I think that less chlorophyll being present would be more likely a result of less being produced. Plant cell constantly turn over cell material, it will also constantly produce more. So if one compares a plant not exposed to acid rain (presumably producing a normal amount of chlorophyll and the exposed plant then one sees that the exposed plant has less chlorophyll than the unexposed plant. I do not think I can answer the rest of your question.

Zymomonas strains transformed with an operon for expression of 2-dehydropantoate reductase and aspartate 1-decarboxylase were able to grow in medium lacking pantothenic acid. These strains may be used for ethanol production without pantothenic acid supplementation in seed culture and fermentation media.

Carboxylic acid sorption regeneration process  

DOE Patents [OSTI]

Carboxylic acids are sorbed from aqueous feedstocks into an organic liquid phase or onto a solid adsorbent. The acids are freed from the sorbent phase by treating it with aqueous alkylamine thus forming an alkylammonium carboxylate which is dewatered and decomposed to the desired carboxylic acid and the alkylamine.

Nucleic acid detection methods  

DOE Patents [OSTI]

The invention relates to methods for rapidly determining the sequence and/or length a target sequence. The target sequence may be a series of known or unknown repeat sequences which are hybridized to an array of probes. The hybridized array is digested with a single-strand nuclease and free 3{prime}-hydroxyl groups extended with a nucleic acid polymerase. Nuclease cleaved heteroduplexes can be easily distinguish from nuclease uncleaved heteroduplexes by differential labeling. Probes and target can be differentially labeled with detectable labels. Matched target can be detected by cleaving resulting loops from the hybridized target and creating free 3-hydroxyl groups. These groups are recognized and extended by polymerases added into the reaction system which also adds or releases one label into solution. Analysis of the resulting products using either solid phase or solution. These methods can be used to detect characteristic nucleic acid sequences, to determine target sequence and to screen for genetic defects and disorders. Assays can be conducted on solid surfaces allowing for multiple reactions to be conducted in parallel and, if desired, automated. 18 figs.

Production of Butyric Acid and Butanol from Biomass  

SciTech Connect (OSTI)

Environmental Energy Inc has shown that BUTANOL REPLACES GASOLINE - 100 pct and has no pollution problems, and further proved it is possible to produce 2.5 gallons of butanol per bushel corn at a production cost of less than $1.00 per gallon. There are 25 pct more Btu-s available and an additional 17 pct more from hydrogen given off, from the same corn when making butanol instead of ethanol that is 42 pct more Btu-s more energy out than it takes to make - that is the plow to tire equation is positive for butanol. Butanol is far safer to handle than gasoline or ethanol. Butanol when substituted for gasoline gives better gas mileage and does not pollute as attested to in 10 states. Butanol should now receive the same recognition as a fuel alcohol in U.S. legislation as ethanol. There are many benefits to this technology in that Butanol replaces gasoline gallon for gallon as demonstrated in a 10,000 miles trip across the United States July-August 2005. No modifications at all were made to a 1992 Buick Park Avenue; essentially your family car can go down the road on Butanol today with no modifications, Butanol replaces gasoline. It is that simple. Since Butanol replaces gasoline more Butanol needs to be made. There are many small farms across America which can grow energy crops and they can easily apply this technology. There is also an abundance of plant biomass present as low-value agricultural commodities or processing wastes requiring proper disposal to avoid pollution problems. One example is in the corn refinery industry with 10 million metric tons of corn byproducts that pose significant environmental problems. Whey lactose presents another waste management problem, 123,000 metric tons US, which can now be turned into automobile fuel. The fibrous bed bioreactor - FBB - with cells immobilized in the fibrous matrix packed in the reactor has been successfully used for several organic acid fermentations, including butyric and propionic acids with greatly increased reactor productivity, final product concentration, and product yield. Other advantages of the FBB include efficient and continuous operation without requiring repeated inoculation, elimination of cell lag phase, good long-term stability, self cleaning and easier downstream processing. The excellent reactor performance of the FBB can be attributed to the high viable cell density maintained in the bioreactor as a result of the unique cell immobilization mechanism within the porous fibrous matrix Since Butanol replaces gasoline in any car today - right now, its manufacturing from biomass is the focus of EEI and in the long term production of our transportation fuel from biomass will stabilize the cost of our fuel - the underpinning of all commerce. As a Strategic Chemical Butanol has a ready market as an industrial solvent used primarily as paint thinner which sells for twice the price of gasoline and is one entry point for the Company into an established market. However, butanol has demonstrated it is an excellent replacement for gasoline-gallon for gallon. The EEI process has made the economics of producing butanol from biomass for both uses very compelling. With the current costs for gasoline at $3.00 per gallon various size farmstead turn-key Butanol BioRefineries are proposed for 50-1,000 acre farms, to produce butanol as a fuel locally and sold locally. All butanol supplies worldwide are currently being produced from petroleum for $1.50 per gallon and selling for $3.80 wholesale. With the increasing price of gasoline it becomes feasible to manufacture and sell Butanol as a clean-safe replacement for gasoline. Grown locally - sold locally at gas prices. A 500 acre farm at 120 bushels corn per acre would make $150,000 at $2.50 per bushel for its corn, when turned into 150,000 gallons Butanol per year at 2.5 gallons per bushel the gross income would be $430,000. Butanol-s advantage is the fact that no other agricultural product made can be put directly into your gas tank without modifying your car. The farmer making and selling locally has no overhead for shippi

Chignell Photochem.Photobiol. 72, 467-471 (2000) Abstract: The tryptophan metabolite xanthurenic acid has been isolated from aged human cataractous lenses. The photophysical properties of xanthurenic acid were examined to determine if it is a potential chromophore for age-related cataractogenesis. We found that xanthurenic acid produces singlet oxygen (F*= 0.17; CD3OD) with the same efficiency as the lenticular chromophore N-formyl kynurenine and quenches singlet oxygen at a rate similar to other tryptophan metabolites (2.1 x 107 M-1 s-1; CD3OD) found in the eye. As the mechanisms of induction of cataracts may also involve redox reactions, the interactions of hydrated electrons (e-aq), the azide radical

Factors controlling naphthenic acid corrosion  

SciTech Connect (OSTI)

A laboratory study was conducted to elucidate the influence of chemical and physical parameters on corrosion of type 1018 carbon steel (CS, UNS G10180) and 5% Cr-0.5% Mo steel in oils containing naphthenic acids (NAs) for application to crude oil refinery systems. Effects of test duration, temperature, and acid concentration were assessed for a range of single acids of varying carbon numbers and for NA mixtures in mineral oil (MO) and in heavy vacuum gas oil (HGVO). In addition, a limited study of the effect of hydrogen sulfide (H{sub 2}S) addition to the acid-oil mixture was conducted. Use of the total acid number (TAN) as a measure of corrosiveness of a crude oil was discredited further. For the same TAN value, molecular size and structure of the acid were shown to have an important influence. Tests conducted in HGVO showed lower corrosion rates than in MO, suggesting inhibition caused by S species in the oil or the steric hindrance of naphtheno-aromatic acids. In oil containing the mixture of NAs, the corrosion rate of type 1018 CS was lower than that for 5% Cr-0.5% Mo steel. The 0.1% H{sub 2}S that passed through the acid-oil mixtures had an inhibiting effect on corrosion. Predicting corrosiveness of a crude oil from the measurement of TAN, distribution of NA composition, and S content and form was particularly challenging. The simple tests used were informative, but further work will be required to establish a standard test method that can provide an adequate ranking of crudes.

Thermal Stability Of Formohydroxamic Acid  

SciTech Connect (OSTI)

The thermal stability of formohydroxamic acid (FHA) was evaluated to address the potential for exothermic decomposition during storage and its use in the uranium extraction process. Accelerating rate calorimetry showed rapid decomposition at a temperature above 65 {degree}?C; although, the rate of pressure rise was greater than two orders of magnitude less than the lower bound for materials which have no explosive properties with respect to transportation. FHA solutions in water and nitric acid did not reach runaway conditions until 150 {degree}?C. Analysis by differential scanning calorimetry showed that FHA melted at 67 {degree}?C and thermally decomposed at 90 {degree}?C with an enthalpy of -1924 J/g. The energics of the FHA thermal decomposition are comparable to those measured for aqueous solutions of hydroxylamine nitrate. Solid FHA should be stored in a location where the temperature does not exceed 20-25 {degree}?C. As a best practice, the solid material should be stored in a climate-controlled environment such as a refrigerator or freezer. FHA solutions in water are not susceptible to degradation by acid hydrolysis and are the preferred way to handle FHA prior to use.

Radioiodinated fatty acid analogs for myocardial imaging  

SciTech Connect (OSTI)

Fatty acids are the preferred substrate for the normoxic heart. About sixty percent of the energy required by the myocardium is provided by fatty acid [beta]-oxidation. Many scientists have focused on the alterations in fatty acid metabolism in the ischemic heart for the development of radiolabelled fatty acids for functional imaging of the heart. Three main categories of compounds were synthesized: tetrazoles (1 and 2), glycidic and [alpha]-methylene acids (3-5), and analogs of oleic acid (6,7 and 7A). The tetrazole group has a similar pKa and size to that of a carboxyl group; however, such fatty acid analogs cannot undergo normal fatty acid metabolism. Glycidic and [alpha]-methylene analogs are potential irreversible inhibitors of fatty acid metabolism. Oleic acid analogs were investigated to assess the affect of stereochemical consequences on biodistribution. The key intermediates in the synthesis of the target compounds were [omega]-nitrophenyl alkylcarboxylic acids and alcohols, which were made using a variety of cross-coupling reactions. The Wittig reaction, which was used in the synthesis of tetrazole 1 and glycidic acid 3, gave low yields of the cross-coupled products. The remaining target compounds were synthesized by condensation of appropriate RCu (CN) ZnI and substituted benzyl bromides or by Pd[sup II] catalyzed cross-coupling of substituted arylhalides with suitable alkynes. The latter two reactions produced much higher yields of the desired products. All of the target compounds were radiolabeled with [sup 125]I by various Cu(I) catalyzed radioiodine exchange procedures and were then subjected to tissue biodistribution (TD) studies in rats. Except for the 15-(4-iodophenyl)-2-methylene-pentadecanoic acid (5), all of the fatty acid analogs failed to surpass clinically-used 15-(4-iodophenyl)pentadecanoic acid (IPPA) in their ability to be taken up and retained by the rat myocardium.

Acid-catalytic decomposition of peracetic acid in the liquid phase  

SciTech Connect (OSTI)

This paper elucidates the kinetic relationships of peracetic acid (PAA) decomposition in the presence of mineral acids and their heterogeneous analogs, polystyrene-di-vinylbenzene cation-exchangers, differing in physicochemical and morphological parameters. It is shown that the thermal decomposition of PAA in acetic acid is an acid-catalyzed reaction. The controlling step of the reaction is protonation of the substrate with formation of an active intermediate form. Sulfonated cation-exchangers are twice as effective as sulfuric acid in this process. Polystyrene-divinylbenzene sulfonated cation-exchangers can be used with success as acid catalysts in oxidation processes involving PAA, because of their high effectiveness, stability, and availability.

The effectiveness of 30 organic acids as inhibitors in engine coolants is reported. Tests include glassware corrosion of coupled and uncoupled metals. FORD galvanostatic and cyclic polarization electrochemistry for aluminum pitting, and reserve alkalinity (RA) measurements. Details of each test are discussed as well as some general conclusions. For example, benzoic acid inhibits coupled metals well but is ineffective on cast iron when uncoupled. In benzoic acid inhibits coupled metals well but is ineffective on cast iron when uncoupled. In general, the organic acids provide little RA when titrated to a pH of 5.5, titration to a pH of 4.5 can result in precipitation of the acid.

SciTech Connect (OSTI)

Inorganic acids are commonly used for surface cleaning and finishing of metals. The acids become unuseable due to contamination with metals or diluted and weakened. Diffusion dialysis has become a way to recover the useable acid and allow separation of the metals for recovery and sale to refineries. This technique is made possible by the use of membranes that are strong enough to withstand low ph and have long service life.

Naphthenic acid corrosion has been a problem in the refining industry for many years. Recently interest in this problem has grown because crudes that contain naphthenic acid are being recovered from areas which were not known to produce this type of crude, such as china, India, and Africa. New techniques for identifying naphthenic acid corrosion and chemical treatments for preventing this attack are presented. Refinery case studies include stream analysis, failure analysis, and inhibitor use. Laboratory tests to show the effect of hydrogen sulfide and phosphorus-based inhibitors are discussed.

Fraud in the acid rain debate  

SciTech Connect (OSTI)

Electric utility executives, according to the author, and millions of other Americans are the victims of a gigantic fraud being carried on in the name of controlling acid rain. This fraud, states the author, involves the distorted, dire image of acidity in nature being created by environmental groups, politicians and others - to gain public sympathy for their legislative goals. The alleged fraud involves the very nature of the legislation being promoted as a low-cost cure for acid rain. On the basis of scientific evidence to date there is no assurance it will reduce acidity by any appreciable amount, but on the other hand it most certainly will cost users of electricity hundreds of billions of dollars in new costs. What has already happened to the nuclear industry is also meant for coal.

Lactic acid fermentation of crude sorghum extract  

SciTech Connect (OSTI)

Crude extract from sweet sorghum supplemented with vetch juice was utilized as the carbohydrate source for fermentative production of lactic acid. Fermentation of media containing 7% (w/v) total sugar was completed in 60-80 hours by Lactobacillus plantarum, product yield averaging 85%. Maximum acid production rates were dependent on pH, initial substrate distribution, and concentration, the rates varying from 2 to 5 g/liter per hour. Under limited medium supplementation the lactic acid yield was lowered to 67%. The fermented ammoniated product contained over eight times as much equivalent crude protein (N x 6.25) as the original medium. Unstructured kinetic models were developed for cell growth, lactic acid formation, and substrate consumption in batch fermentation. With the provision of experimentally determined kinetic parameters, the proposed models accurately described the fermentation process. 15 references.

Catalytic oxidative conversion of cellulosic biomass to formic acid and acetic acid with exceptionally high yields  

Science Journals Connector (OSTI)

Abstract Direct conversion of raw biomass materials to fine chemicals is of great significance from both economic and ecological perspectives. In this paper, we report that a Keggin-type vanadium-substituted phosphomolybdic acid catalyst, namely H4PVMo11O40, is capable of converting various biomass-derived substrates to formic acid and acetic acid with high selectivity in a water medium and oxygen atmosphere. Under optimized reaction conditions, \\{H4PVMo11O40\\} gave an exceptionally high yield of formic acid (67.8%) from cellulose, far exceeding the values achieved in previous catalytic systems. Our study demonstrates that heteropoly acids are generally effective catalysts for biomass conversion due to their strong acidities, whereas the composition of metal addenda atoms in the catalysts has crucial influence on the reaction pathway and the product selectivity.

Photoenhanced anaerobic digestion of organic acids  

DOE Patents [OSTI]

A process is described for rapid conversion of organic acids and alcohols anaerobic digesters into hydrogen and carbon dioxide, the optimal precursor substrates for production of methane. The process includes addition of photosynthetic bacteria to the digester and exposure of the bacteria to radiant energy (e.g., solar energy). The process also increases the pH stability of the digester to prevent failure of the digester. Preferred substrates for photosynthetic bacteria are the organic acid and alcohol waste products of fermentative bacteria. In mixed culture with methanogenic bacteria or in defined co-culture with non-aceticlastic methanogenic bacteria, photosynthetic bacteria are capable of facilitating the conversion or organic acids and alcohols into methane with low levels of light energy input.

A method to attenuate U(VI) mobility in acidic waste plumes using humic acids  

SciTech Connect (OSTI)

Acidic uranium (U) contaminated plumes have resulted from acid-extraction of plutonium during the Cold War and from U mining and milling operations. A sustainable method for in-situ immobilization of U under acidic conditions is not yet available. Here, we propose to use humic acids (HAs) for in-situ U immobilization in acidic waste plumes. Our laboratory batch experiments show that HA can adsorb onto aquifer sediments rapidly, strongly and practically irreversibly. Adding HA greatly enhanced U adsorption capacity to sediments at pH below 5.0. Our column experiments using historically contaminated sediments from the Savannah River Site under slow flow rates (120 and 12 m/y) show that desorption of U and HA were non-detectable over 100 pore-volumes of leaching with simulated acidic groundwaters. Upon HA-treatment, 99% of the contaminant [U] was immobilized at pH < 4.5, compared to 5% and 58% immobilized in the control columns at pH 3.5 and 4.5, respectively. These results demonstrated that HA-treatment is a promising in-situ remediation method for acidic U waste plumes. As a remediation reagent, HAs are resistant to biodegradation, cost effective, nontoxic, and easily introducible to the subsurface.

15 - Chemical production from lignocellulosic biomass: thermochemical, sugar and carboxylate platforms  

Science Journals Connector (OSTI)

Abstract: Lignocellulose is abundant, inexpensive, and renewable. Further, it can replace fossil fuels as our primary source for chemicals and energy. To transition from fossil fuels to lignocellulose-based chemicals and fuels, an economically viable commercial biorefinery must be developed. This chapter reviews three major chemical platforms for a biorefinery. The thermochemical platform thermally degrades biomass into gaseous, liquid, and solid components. The sugar platform utilizes enzymes and/or chemicals to create sugars. The carboxylate platform ferments biomass into carboxylic acids/salts. The intermediate products of these three platforms serve as a ‘biocrude’ for the production of chemicals and fuels from lignocellulose.

CONCEPTUAL DESIGN ASSESSMENT FOR THE CO-FIRING OF BIO-REFINERY SUPPLIED LIGNIN PROJECT  

SciTech Connect (OSTI)

The major aspects of this project are proceeding toward completion. Prior to this quarter, design criteria, tentative site selection, facility layout, and preliminary facility cost estimates were completed and issued. Processing of bio-solids was completed, providing material for the pilot operations. Pilot facility hydrolysis production has been completed to produce lignin for co-fire testing and the lignin fuel was washed and dewatered. Both the lignin and bio-solids fuel materials for co-fire testing were sent to the co-fire facility (EERC) for evaluation and co-firing. EERC has received coal typical of the fuel to the TVA-Colbert boilers. This material was used at EERC as baseline material and for mixing with the bio-fuel for combustion testing. All the combustion and fuel handling tests at EERC have been completed. During fuel preparation EERC reported no difficulties in fuel blending and handling. Preliminary co-fire test results indicate that the blending of lignin and bio-solids with the Colbert coal blend generally reduces NO{sub x} emissions, increases the reactivity of the coal, and increases the ash deposition rate on superheater surfaces. Deposits produced from the fuel blends, however, are more friable and hence easier to remove from tube surfaces relative to those produced from the baseline Colbert coal blend. The final co-fire testing report is being prepared at EERC and will be completed by the end of the second quarter of 2002. The TVA-Colbert facility has neared completion of the task to evaluate co-location of the Masada facility on the operation of the power generation facility. The TVA-Colbert fossil plant is fully capable of providing a reliable steam supply. The preferred steam supply connection points and steam pipeline routing have been identified. The environmental review of the pipeline routing has been completed and no major impacts have been identified. Detailed assessment of steam export impacts on the Colbert boiler system have been completed and a cost estimate for the steam supply system was completed. The cost estimate and output and heat rate impacts have been used to determine a preliminary price for the exported steam. TVA is further evaluating the impacts of adding lignin to the coal fuel blend and how the steam cost is impacted by proximity of the Masada biomass facility.

Critical review of naphthenic acid corrosion  

SciTech Connect (OSTI)

Naphthenic acid corrosion continues to be a reliability issue in refinery distillation units. A review of the subject is presented herein with special focus on field and laboratory data and on areas where research is needed. The review shows that several parameters are known to affect the corrosion process and their individual effect on crude corrosivity are somewhat understood. However, their combined effect is still subject to much controversy. The determination of a critical factor--naphthenic acid content--is still not standardized. It is shown herein that, by arranging the literature findings into three groups (1) furnace tubes and transfer lines, (2) vacuum column and (3) side cut piping, a better agreement of the literature data is achieved.

Naphthenic acid corrosion in synthetic fuels production  

SciTech Connect (OSTI)

Serious corrosion damage to carbon steel piping in a fractionation unit associated with synthetic fuels production has been ascribed to the presence of naphthenic acids. Investigation of the problem revealed total acids numbers (TAN) ranging from 8--12mg KOH/g in the feed to the unit. Damage typically occurred in the temperature range 180--240 C and manifested as localized pitting, preferential weld corrosion, general wall thinning and end-grain attack. Filming amine corrosion inhibitors designed for refinery overhead systems have been proven ineffective and high temperature phosphate-based inhibitors could not be used due to potential catalyst poisoning in downstream refinery units. Coupon exposures indicated corrosion rates in the order of 2 mm/y on carbon steel in a reboiler line as well as pitting to austenitic stainless steel type UNS S30403. Line replacement in austenitic stainless steel UNS S31603 has been proven effective. The performance of this alloy is mainly ascribed to its molybdenum content. The absence of sulfur in the feed to the unit is also contributing to the alloy performance despite the extremely high total acid numbers.

Phosphatidic acid: an emerging plant lipid second messenger  

Science Journals Connector (OSTI)

Evidence is accumulating that phosphatidic acid is a second messenger. Its level increases within minutes of a wide variety of stress treatments including ethylene, wounding, pathogen elicitors, osmotic and oxidative stress, and abscisic acid. Enhanced signal levels are rapidly attenuated by phosphorylating phosphatidic acid to diacylglycerol pyrophosphate. Phosphatidic acid is the product of two signalling pathways, those of phospholipases C and D, the former in combination with diacylglycerol kinase. Families of these genes are now being cloned from plants. Several downstream targets of phosphatidic acid have been identified, including protein kinases and ion channels.

Continuous-flow free acid monitoring method and system  

DOE Patents [OSTI]

A free acid monitoring method and apparatus is provided for continuously measuring the excess acid present in a process stream. The disclosed monitoring system and method is based on the relationship of the partial pressure ratio of water and acid in equilibrium with an acid solution at constant temperature. A portion of the process stream is pumped into and flows through the monitor under the influence of gravity and back to the process stream. A continuous flowing sample is vaporized at a constant temperature and the vapor is subsequently condensed. Conductivity measurements of the condensate produces a nonlinear response function from which the free acid molarity of the sample process stream is determined.

Naphthenic acids as antiwear additives for jet fuels  

SciTech Connect (OSTI)

One of the ways in which the antiwear properties of jet fuels can be improved is the use of lubricity agents, otherwise known as antiwear additives. Among the various compounds that have antiwear properties in these fuels, naphthenic, acids merit special attention. These are alicyclic carboxylic acids, in most cases monobasic, with five- and six-membered carbon rings; they have the general formula R(CH{sub 2}){sub n}COOH, where R is a naphthene radical. Natural naphthenic acids consist mainly of acids of the cyclopentane series, beginning with the simplest, in particular cyclopentylacetic acid. The lower naphthenic acids are monocyclic; the higher acids, beginning with C{sub 13}, are bicyclic and polycyclic. Naphthenic acids of the cyclohexane series are encountered less frequently; they may be found, for example, in Baku, California, and Sakhalin crudes. The most widely used method for obtaining naphthenic acids is the treatment of light distillates, lube distillates, and diesel fuels. The standard GOST 13302-77 establishes several grades of naphthenic acids, depending on the raw material and the production technology. This work was aimed at the utilization of wastes containing naphthenic acids, with subsequent use as jet fuel additives.

Interaction of Uranium(VI) with Phthalic Acid  

SciTech Connect (OSTI)

Phthalic acid, a ubiquitous organic compound found in soil, water, and in domestic and nuclear wastes can affect the mobility and bioavailability of metals and radionuclides. We examined the complexation of uranium with phthalic acid by potentiometric titration, electrospray ionization-mass spectroscopy (ESI-MS), and extended X-ray absorption fine structure (EXAFS) analysis. Potentiometric titration of a 1:1 U/phthalic acid indicated uranyl ion bonding with both carboxylate groups of phthalic acid; above pH 5 the uranyl ion underwent hydrolysis with one hydroxyl group coordinated to the inner-sphere of uranium. In the presence of excess phthalic acid, ESI-MS analysis revealed the formation of both 1:1 and 1:2 U/phthalic acid complexes. EXAFS studies confirmed the mononuclear biligand 1:2 U/phthalic acid complex as the predominant form. These results show that phthalates can form soluble stable complexes with uranium and may affect its mobility.

Phosphoric acid impurities in phosphoric acid fuel cell electrolytes. 2: Effects on the oxygen reduction reaction at platinum electrodes  

SciTech Connect (OSTI)

The effects of phosphorus acid additions on the oxygen reduction reaction at platinum electrodes in concentrated phosphoric acid were studied. The oxygen reduction currents decreased, and the Tafel slopes became more negative upon the addition of small concentrations of phosphorus acid. In addition,the phosphorus acid oxidation current tended to complete with the oxygen reduction current. These effects became more pronounced at higher phosphorus acid concentrations and at higher temperatures. Upon the addition of phosphorus acid the number of electrons involved in the oxygen reduction reaction decreased from a value close to four to a value approaching two, suggesting promotion of a two-electron reduction to peroxide. Therefore, in studies of the electrochemical reduction of oxygen in hot concentrated phosphoric acid or in fuel cell systems using hot concentrated phosphoric acid as electrolyte, it is recommended that precautions be taken against the inadvertent formation of the phosphorus acid. The removal of phosphorus acid from concentrated phosphoric acid by repeated potential cycling at 100 mV/s between + 0.5 and +1.50 V (vs. dynamic hydrogen electrode) was demonstrated.

Nucleic acid amplification using modular branched primers  

DOE Patents [OSTI]

Methods and compositions expand the options for making primers for use in amplifying nucleic acid segments. The invention eliminates the step of custom synthesis of primers for Polymerase Chain Reactions (PCR). Instead of being custom-synthesized, a primer is replaced by a combination of several oligonucleotide modules selected from a pre-synthesized library. A modular combination of just a few oligonucleotides essentially mimics the performance of a conventional, custom-made primer by matching the sequence of the priming site in the template. Each oligonucleotide module has a segment that matches one of the stretches within the priming site.

Solvent extraction of rare-earth metals by carboxylic acids  

SciTech Connect (OSTI)

The solvent extraction of the trivalent lanthanides and yttrium from nitrate media by solutions of carboxylic acids in xylene has been studied. Commercially available carboxylic acids such as Versatic 10 and naphthenic acids were used, as well as model compounds of known structure, such as 2-ethylhexanoic and 3-cyclohexylpropanoic acids. In a few cases, extraction of the metals from sulphate and chloride solutions was also investigated. The dependence of the extraction properties of the carboxylic acids on the atomic number of the lanthanide shows a definite relationship to the steric bulk of the carboxylic acid molecule quantified by means of the steric parameter, E{sub s}{prime} of the substituent alkyl group. The stoichiometries of the extracted complexes for representative light (La), middle (Gd) and heavy (Lu) rare-earth metals were investigated by the slope-analysis technique for a sterically hindered acid (Versatic 10 acid; -E{prime}{sub s} = 3.83) and an acid with low steric hindrance (3-cyclohexylpropanoic acid; -E{prime}{sub s} = 0.28). 14 refs., 13 figs., 3 tabs.

Newer method for analyzing naphthenic acids in petroleum  

SciTech Connect (OSTI)

The naphthenic acids in petroleum are considered a class of biological markers. Their potential use in source correlation and as indicator of biodegradation have been reported in the past. Their presence in waste water at refineries may also cause corrosion problems and fish toxicity. Due to their highly complicated nature, detailed characterization of the acids has been difficult and time consuming. This talk will describe a relatively simple approach in characterizing the acids based on their group types. The acids were first separated from petroleum followed by mass spectrometric determinations. Two newer methods were developed to analyze the acid components, namely Chemical Ionization with NF{sub 3} as reagent gas and negative ion Fast Atom Bombardment. The geochemical interpretation based on acid distribution will be demonstrated with a set of well understood crude oil samples.

The iron powder test for naphthenic acid corrosion studies  

SciTech Connect (OSTI)

In the course of an ongoing investigation into the phenomenon of naphthenic acid corrosion, a new test method has evolved and is currently being further developed to substitute the total acid number (TAN or neutralization number) as an indicator for naphthenic acid corrosion potential. It can also be used to complement conventional autoclave corrosion tests in high temperature environments, which are based on weight loss of steel coupons. In this new method an oil sample reacts with pure iron powder within an autoclave heated to the testing temperature. The result is based on the amount of dissolved iron found in the oil sample. The oil sample can dissolve an amount of iron for a given time at a given temperature, depending on the naphthenic acid corrosion, since these acids react with iron to produce oil soluble iron naphthenates. This paper describes the method, compares it with conventional crude corrosiveness testing, and proposes it as a new way of measuring naphthenic acid corrosion potential.

Crude oils containing naphthenic acids can cause a variety of corrosion problems in any of several process areas. But because of the complexity of naphthenic acid corrosion, no routine technique is available for predicting corrosion from this source. Certain high-temperature corrosion inhibitors with a general phosphate ester structure have shown good mitigation of naphthenic acid corrosion in commercial applications. A description of two such cases will help refiners know what to look for to prevent similar occurrences in their plants.

A First Look at Yeast Fatty Acid A First Look at Yeast Fatty Acid Synthase A First Look at Yeast Fatty Acid Synthase Print Wednesday, 28 November 2007 00:00 Fatty acids are the major constituents of eukaryotic and bacterial cellular membranes. They are used for functionally important post-translational protein modifications, and chains of fatty acids are the main storage compartments of an organism's chemical energy. Fatty acid synthesis is carried out by fatty acid sythase (FAS), which catalyzes cycles of multistep chemical reactions that are essentially the same in all organisms. FAS uses one acetyl-coenzyme A (CoA) and seven malonyl-CoA molecules to synthesize the 16-carbon palmitic acid, the most abundant fatty acid in eukaryotes. Now, for the first time, a group of researchers has determined the atomic structure of yeast Saccharomyces cerevisiae FAS derived from two crystals of the enzyme, using data collected at ALS Beamlines 8.2.1 and 8.2.2, as well as other synchrotron facilities.

A novel recycling process using the treated citric acid wastewater as ingredients water for citric acid production  

Science Journals Connector (OSTI)

Abstract In this study, an integrated process coupling citric acid and methane fermentations was proposed to solve severe wastewater pollution problem in cassava-based citric acid production. The accumulation patterns of the potential and major inhibitors in this process, including organic compounds, volatile fatty acids (VFAs), total ions and pigments were investigated. Both simulation and experimental results indicated that these inhibitors could reach their equilibrium levels after 3–7 fermentation runs when reutilizing the treated citric acid wastewater. As a result, the proposed citric acid fermentation process by recycling the wastewater treated in methane fermentation could be stably operated for more than 15 runs, which could save a large amount of fresh water and relieve the severe wastewater pollution in citric acid production potentially.

Further studies of the interactions of divalent metal ions with triethylenetetraminehexaacetic acid (TTHA) have revealed that mononuclear, binuclear, and protonated mononuclear complexes are formed in solution with Zn(II), Cd(II), Hg(II) and Pb(II) iions. Equilibrium constants are reported for the various complex species formed, and possible structures for the mononuclear are reported for the various complex species formed, and possible structures for the mononuclear species are suggested. Other reports describing the nature of the complexes formed by this ligand with divalent metal ions are confirmed in that the binuclear complexes are resistant to hydrolysis in alkaline solution, and that the symmetrical binuclear complex is considered the most likely structure.

Naphthenic acid corrosion and its control  

SciTech Connect (OSTI)

This paper first presents a brief description of naphthenic acid corrosion and the main factors which influence its onset and severity. After a brief discussion of traditional control methods, it proceeds to a discussion of chemical inhibition, which is a relatively new control technique. Chemical inhibitors can be divided into two broad classifications: phosphorus-based and non-phosphorus-based. Three types of phosphorus-based inhibitors have been reported: amine-neutralized phosphate esters, alkaline earth phosphonate phenate sulfide plus trialkyl phosphate, and thiazolines plus di and tri-alkyl phosphates. Non-phosphorus based inhibitors include: thiazolines, organic polysulfides, and sulfonated alkyl phenols. A description of each inhibitor and its effectiveness in the laboratory and field is presented.

Corrosion of carbons in acid electrolytes  

SciTech Connect (OSTI)

The stability of the electrode materials used in hot phosphoric acid fuel cells, in particular the conductive carbon electrocatalyst support, is a continuing concern. The Tafel slope of the carbon corrosion reaction appears to be indicative of the degree of disorder on the carbon surface--the larger the Tafel slope, the greater the degree of disorder. The effect of heat-treatment was found to depend on the structure of the parent carbon. Differences in the electrochemical behavior of samples of heattreated Vulcan XC-72R were correlated with the structural properties of the carbon produced, as reflected by lattice parameters. Changes in BET surface areas and lattice parameters as well as in electrochemical behavior showed evidence that the addition of boron resulted in ''graphitization'' that was not achieved by heat-treatment alone.

EFFECTS OF NITRIC ACID ON CRITICALITY SAFETY ANALYSIS  

SciTech Connect (OSTI)

As nitric acid molarity is increased, there are two competing phenomena affecting the reactivity of the system. First, there is interaction between each of the 10 wells in the basket-like insert. As the molarity of the nitric acid solution is increased (it moves from 100% water to 100% HNO{sub 3}), the hydrogen atom density decreases by about 80%. However, it remains a relatively efficient moderator. The moderating ratio of nitric acid is about 90% that of water. As the media between the wells is changed from 100% water to 100% nitric acid, the density of the media increases by 50%. A higher density typically leads to a better reflector. However, when the macroscopic scattering cross sections are considered, nitric acid is a much worse reflector than water. The effectiveness of nitric acid as a reflector is about 40% that of water. Since the media between the wells become a worse reflector and still remains an effective moderator, interaction between the wells increases. This phenomenon will cause reactivity to increase as nitric acid molarity increases. The seond phenomenon is due to the moderating ratio changing in the high concentration fissile-nitric acid solution in the 10 wells. Since the wells contain relatively small volumes of high concentration solutions, a small decrease in moderating power has a large effect on reactivity. This is due to the fact that neutrons are more likely to escape the high concentration fissile solution before causing another fission event. The result of this phenomenon is that as nitric acid molarity increases, reactivity decreases. Recent studies have shown that the second phenomenon is indeed the dominating force in determining reactivity changes in relation to nitric acid molarity changes. When considering the system as a whole, as nitric acid molarity increases, reactivity decreases.

Abstract Glucosamine is a basic unit of the chitin/chitosan structure, which is derived from crustacean (e.g. crab, shrimp) and insect shells. In this study, the production of levulinic acid (LA) from glucosamine via dilute-acid-catalyzed hydrothermal hydrolysis was investigated. Among the reaction conditions, reaction temperature, reaction time, and substrate concentration were more effective than catalyst concentration. The optimal conditions for LA production, as determined by the response-surface methodology (RSM), were as follows: 188 °C reaction temperature, 4 wt% catalyst concentration, 49 min reaction time, 120 g/L substrate concentration. Under these conditions, the LA yield was 30.3 g/L (25.3 wt%), while the 5-HMF concentration was zero. These results might provide basic knowledge essential to the production of valuable chemicals derivable from renewable marine resources and utilizable as fuel additives and polymer building blocks.

Behavior of copper in acidic sulfate solution: Comparison with acidic chloride  

SciTech Connect (OSTI)

The anodic polarization behavior of copper in a 0.1 M sulfuric acid (H{sub 2}SO{sub 4}) + 1 M sodium sulfate (Na{sub 2}SO{sub 4}) solution (pH = 2.0) was studied at room temperature under quiescent and stirred conditions. The behavior was compared with aqueous equilibria via construction of a potential-vs-pH (E-pH) diagram for the copper-sulfate-water (Cu-SO{sub 4}{sup 2}-H{sub 2}O) system. Interpretation of the behavior was aided by comparison with aqueous equilibria and polarization studies of copper in a 0.2 M hydrochloric acid (HCl) + 1 M sodium chloride (NaCl) solution(pH = 0.8). The initial anodic dissolution region in the acidic sulfate solution exhibited Tafel behavior with a slope consistent with formation of cupric ions (Cu{sup 2+}) whose rate of formation was charge-transfer controlled. At higher potentials, limiting current density (i{sub L}) behavior was observed under E-pH conditions that were consistent with formation of a film of copper sulfate pentahydrate (CuSO{sub 4} {degree} 5H{sub 2}O). Comparison of experimental i{sub L} values with those predicted by mass transport-controlled processes, using estimates of the diffusion layer thickness obtained from the mass transfer-influenced region of apparent Tafel behavior in the acidic chloride solution, were in sufficient agreement to indicate i{sub L} was controlled by the rate of dissolution of the CuSO{sub 4} {degree} 5H{sub 2}O film via transport of Cu{sup 2+} from the film-electrolyte interface into the bulk solution.

Abc Amino Acids: Design, Synthesis, and Properties of New Photoelastic Amino Acids  

SciTech Connect (OSTI)

Photoisomerizable amino acids provide a direct avenue to the experimental manipulation of bioactive polypeptides, potentially allowing real-time, remote control of biological systems and enabling useful applications in nanobiotechnology. Herein, we report a new class of photoisomerizable amino acids intended to cause pronounced expansion and contraction in the polypeptide backbone, i.e., to be photoelastic. These compounds, termed Abc amino acids, employ a photoisomerizable azobiphenyl chromophore to control the relative disposition of aminomethyl and carboxyl substituents. Molecular modeling of nine Abc isomers led to the identification of one with particularly attractive properties, including the ability to induce contractions up to 13A in the backbone upon transa?cis photoisomerization. This isomer, designated mpAbc, has substituents at meta and para positions on the inner (azo-linked) and outer rings, respectively. An efficient synthesis of Fmoc-protected mpAbc was executed in which the biaryl components were formed via Suzuki couplings and the azo linkage was formed via amine/nitroso condensation; protected forms of three other Abc isomers were prepared similarly. A decapeptide incorporating mpAbc was synthesized by conventional solid-phase methods and displayed characteristic azobenzene photochemical behavior with optimal conversion to the cis isomer at 360 nm and a thermal cisa?trans half life of 100 min. at 80 AoC.

GENETIC ANALYSIS OF ABSCISIC ACID BIOSYNTHESIS  

SciTech Connect (OSTI)

The carotenoid cleavage dioxygenases (CCD) catalyze synthesis of a variety of apo-carotenoid secondary metabolites in plants, animals and bacteria. In plants, the reaction catalyzed by the 11, 12, 9-cis-epoxy carotenoid dioxygenase (NCED) is the first committed and key regulated step in synthesis of the plant hormone, abscisic acid (ABA). ABA is a key regulator of plant stress responses and has critical functions in normal root and seed development. The molecular mechanisms responsible for developmental control of ABA synthesis in plant tissues are poorly understood. Five of the nine CCD genes present in the Arabidopsis genome encode NCED's involved in control of ABA synthesis in the plant. This project is focused on functional analysis of these five AtNCED genes as a key to understanding developmental regulation of ABA synthesis and dissecting the role of ABA in plant development. For this purpose, the project developed a comprehensive set of gene knockouts in the AtNCED genes that facilitate genetic dissection of ABA synthesis. These mutants were used in combination with key molecular tools to address the following specific objectives: (1) the role of ABA synthesis in root development; (2) developmental control of ABA synthesis in seeds; (3) analysis of ATNCED over-expressers; (4) preliminary crystallography of the maize VP14 protein.

Fate of the naphthenic acid, U-{sup 14}C-palmitic acid, in constructed wetlands; A microcosm study  

SciTech Connect (OSTI)

This study represents part of an overall initiative to assess the ecological viability of constructed wetlands for the treatment of oil sands wastewater. To determine the fate of naphthenic acids (C{sub n}H{sub 2n+z}O{sub 2}), the most toxic component of oil sands wastewater, in constructed wetlands, a representative naphthenic acid (NA), U-{sup 14}C-palmitic acid was added to microcosms placed within three control and three treatment wetlands. Treatment wetlands receive wastewater typical of effluent resulting from the oil sands extraction process. In each of the 6 microcosms, biotic compartments measured for {sup 14}C at t = 0, 1, 3, 5, 7, 14 and 21 days were: mineralized palmitic acid (evolved {sup 14}C-CO{sub 2}), water, suspended sediments, bottom sediments, cattail, chironomid larvae, and sticklebacks (liver, muscle and skin). The fate of the {sup 14}C-palmitic acid was similar between the control versus treatment microcosms. Exceptions were greater amounts of {sup 14}C-palmitic acid detected in water and suspended sediments of treatment versus control microcosms. Of the biotic compartments, at t = 21 days, the majority of the {sup 14}C-palmitic acid was found in chironomids and fish tissues. Mineralization and partitioning of {sup 14}C-palmitic acid onto sediments also represented important fates. From the initial addition of the labelled compound, with the exception of bottom sediments, by t = 1 day {sup 14}C was detected in ail biotic compartments. {sup 14}C was detected in bottom sediments by t = 7 days. These results indicate that in addition to mineralization being an important process influencing the fate palmitic acid within the wetlands, partitioning into biotic compartments such as chironomids and fish are also important fates. Hence, when considering the use of constructed wetlands for the treatment of oil sands effluent, the adverse effects of naphthenic acids on the biota needs to be fully addressed.

Process for removing naphthenic acids from petroleum distillates  

SciTech Connect (OSTI)

A liquid extraction process is described for removing naphthenic acids from naphthenic acid containing petroleum distillates boiling within the range of about 180/sup 0/-600/sup 0/C. and having an acid number of at least about 0.2 which process comprises the steps of: (a) intimately contacting the petroleum distillates with a solvent consisting essentially of methanol, water, and about from 2-20 wt. % ammonia and having a methanol: water ratio in the range of about from 0.2 to 3 parts by weight of methanol per part by weight of water and using an ammonia to petroleum distillate ratio of about 0.1-1 part by weight of ammonia per 100 parts by weight of the petroleum distillate. This selectively extracts the naphthenic acids into the solvent and yielding an immiscible two-phase liquid mixture, one of which is naphthenic acid-rich solvent phase and the other of which is a substantially napthenic acid-free petroleum distillate phase; and (b) separating and respectively recovering the naphtenic acid-rich solvent phase and petroleum distillate phase.

Ursolic acid improves domoic acid-induced cognitive deficits in mice  

SciTech Connect (OSTI)

Our previous findings suggest that mitochondrial dysfunction is the mechanism underlying cognitive deficits induced by domoic acid (DA). Ursolic acid (UA), a natural triterpenoid compound, possesses many important biological functions. Evidence shows that UA can activate PI3K/Akt signaling and suppress Forkhead box protein O1 (FoxO1) activity. FoxO1 is an important regulator of mitochondrial function. Here we investigate whether FoxO1 is involved in the oxidative stress-induced mitochondrial dysfunction in DA-treated mice and whether UA inhibits DA-induced mitochondrial dysfunction and cognitive deficits through regulating the PI3K/Akt and FoxO1 signaling pathways. Our results showed that FoxO1 knockdown reversed the mitochondrial abnormalities and cognitive deficits induced by DA in mice through decreasing HO-1 expression. Mechanistically, FoxO1 activation was associated with oxidative stress-induced JNK activation and decrease of Akt phosphorylation. Moreover, UA attenuated the mitochondrial dysfunction and cognitive deficits through promoting Akt phosphorylation and FoxO1 nuclear exclusion in the hippocampus of DA-treated mice. LY294002, an inhibitor of PI3K/Akt signaling, significantly decreased Akt phosphorylation in the hippocampus of DA/UA mice, which weakened UA actions. These results suggest that UA could be recommended as a possible candidate for the prevention and therapy of cognitive deficits in excitotoxic brain disorders. - Highlights: • Ursolic acid (UA) is a naturally triterpenoid compound. • UA attenuated the mitochondrial dysfunction and cognitive deficits. • Mechanistically, UA activates PI3K/Akt signaling and suppresses FoxO1 activity. • UA could be recommended as a possible candidate for anti-excitotoxic brain disorders.

Human retroviruses and AIDS 1996. A compilation and analysis of nucleic acid and amino acid sequences  

SciTech Connect (OSTI)

This compendium and the accompanying floppy diskettes are the result of an effort to compile and rapidly publish all relevant molecular data concerning the human immunodeficiency viruses (HIV) and related retroviruses. The scope of the compendium and database is best summarized by the five parts that it comprises: (1) Nuclear Acid Alignments and Sequences; (2) Amino Acid Alignments; (3) Analysis; (4) Related Sequences; and (5) Database Communications. Information within all the parts is updated throughout the year on the Web site, http://hiv-web.lanl.gov. While this publication could take the form of a review or sequence monograph, it is not so conceived. Instead, the literature from which the database is derived has simply been summarized and some elementary computational analyses have been performed upon the data. Interpretation and commentary have been avoided insofar as possible so that the reader can form his or her own judgments concerning the complex information. In addition to the general descriptions of the parts of the compendium, the user should read the individual introductions for each part.

Extraction of nitric acid, uranyl nitrate, and bismuth nitrate from aqueous nitric acid solutions with CMPO  

SciTech Connect (OSTI)

DOE sponsored development of the transuranium extraction (TRUEX) process for removing actinides from radioactive wastes. The solvent is a mixture of CMPO and TBP. Since the extraction characteristics of CMPO are not as well understood as those of TBP, the extraction of nitric acid, uranyl nitrate, and bismuth nitrate with CMPO (dissolved in n-dodecane) were studied. Results indicate that CMPO extracts nitric acid with a 1:1 stoichiometry; equilibrium constant is 2. 660{plus_minus}0.092 at 25 C, and extraction enthalpy is -5. 46{plus_minus}0.46 kcal/mol. Slope analysis indicates that uranyl nitrate extracts with a mixed equilibria of 1:1 and 2:1 stoichiometries in nearly equal proportion. Equil. constant of the 2: 1 extraction was 1.213 {times} 10{sup 6}{plus_minus}3.56 {times} 10{sup 4} at 25 C; reaction enthalpy was -9.610{plus_minus}0.594 kcal/mol. Nitration complexation constant is 8.412{plus_minus}0.579, with an enthalpy of -10.72{plus_minus}1.87 kcal/mol. Bismuth nitrate also extracts with a mixed equilibria of (perhaps) 1:1 and 2:1 stoichiometries. A 2:1 extraction equilibrium and a nitrate complexation adequately model the data. Kinetics and enthalpies were also measured.

Alternative Non-Acid Eluants for Spherical Resorcinol-Formaldehyde  

SciTech Connect (OSTI)

Small-column ion exchange (SCIX) units installed in or near high-level waste tanks to remove Cs-137 from highly alkaline solutions are among the waste treatment plans in the DOE Complex. Spherical Resorcinol-Formaldehyde (sRF) is the ion exchange (IX) resin under consideration for SCIX at the Hanford site. The elution step of the multi-step IX process is typically done with nitric acid. An acid eluant is a potential hazard in the event of a spill, leak, etc. because the waste tanks are made of carbon steel. Corrosion and associated structural damage may ensue. A non-acid eluant may be a viable alternative. It will eliminate the need for special acid handling requirements within the tank farms.

JGI - Why Sequence Euryarchaeota in Acid Mine Drainage?  

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

Euryarchaeota in Acid Mine Drainage? Euryarchaeota in Acid Mine Drainage? Acid mine drainage (AMD) is a major worldwide environmental problem associated with the mining of energy resources (coal and uranium) and metals (eg., iron and copper), thus of direct DOE relevance. The processes that underpin AMD formation can be harnessed for bioleaching and bioremediation. Many scientific and industrial groups are studying various aspects of the biogeochemistry of AMD generation. Random shotgun sequencing of an extremely acidic (pH <0.9) chemolithotrophic subsurface AMD biofilm community (from the Richmond Mine in Iron Mountain, California) recovered a genome fragment from a novel euryarchaeon, named WTF-1. This novel lineage was previously missed by common broad-specificity primers used for PCR-based surveys. Further study

Ionic Ckonductivity and Glass Transition of Phosphoric Acids  

SciTech Connect (OSTI)

Here we report the low-temperature dielectric and viscoelastic properties of phosphoric acids in the range of H2O:P2O5 1.5 5. Both dielectric and viscosity measurements allow us to determine the glass-transition temperatures of phosphoric acids. The obtained glass-transition temperatures are in good agreement with previous differential scanning calorimetric measurements. Moreover, our analysis reveals moderate decoupling of ionic conductivity from structural relaxation in the vicinity of the glass transition.

SciTech Connect (OSTI)

Here we report the low-temperature dielectric and viscoelastic properties of phosphoric acids in the range of H2O:P2O5 1.5 5. Both dielectric and viscosity measurements allow us to determine the glass-transition temperatures of phosphoric acids. The obtained glass-transition temperatures are in good agreement with previous differential scanning calorimetric measurements. Moreover, our analysis reveals moderate decoupling of ionic conductivity from structural relaxation in the vicinity of the glass transition.

Carbobenzoxy amino acids: Structural requirements for cholecystokinin receptor antagonist activity  

SciTech Connect (OSTI)

The authors used dispersed acini prepared from guinea pig pancreas to examine 28 carbobenzoxy (CBZ) amino acids for their abilities to function as cholecystokinin receptor antagonists. All amino acid derivatives tested, except for CBZ-alanine, CBZ-glycine, and N alpha-CBZ- lysine, were able to inhibit the stimulation of amylase secretion caused by the C-terminal octapeptide of cholecystokinin. In general, there was a good correlation between the ability of a carbobenzoxy amino acid to inhibit stimulated amylase secretion and the ability of the amino acid derivative to inhibit binding of /sup 125/I-cholecystokinin. The inhibition of cholecystokinin-stimulated amylase secretion was competitive, fully reversible, and specific for those secretagogues that interact with the cholecystokinin receptor. The potencies with which the various carbobenzoxy amino acids inhibited the action of cholecystokinin varied 100-fold and CBZ-cystine was the most potent cholecystokinin receptor antagonist. This variation in potency was primarily but not exclusively a function of the hydrophobicity of the amino acid side chain.

Effects of charge-carrying amino acids on the gelatinization and retrogradation properties of potato starch  

Science Journals Connector (OSTI)

Abstract The objective of this study was to evaluate the effects of charge-carrying amino acids (lysine (Lys), arginine (Arg), aspartic acid (Asp) and glutamic acid (Glu)) on the gelatinization and retrogradation properties of potato starch. Acidic amino acids (Asp and Glu) showed a decreasing trend in swelling power and granule size of potato starch, but increased amylose leaching and gelatinization temperature. Alkaline amino acid (Arg) showed an increasing trend in swelling power and granule size of potato starch, but decreasing amylose leaching and gelatinization temperature. Lys had no effect on the swelling power of potato starch, except at a high content (0.2 mol/kg). Like other two acidic amino acids, Lys also increased gelatinization temperature. Moreover, the addition of alkaline amino acids (Arg) decreased syneresis value of potato starch but acidic amino acids (Asp and Glu) increased it. Compared to Arg, the syneresis of potato starch with Lys was similar to that of its native starch.

Comparative Genomics of Regulation of Fatty Acid and Branched-chain Amino Acid Utilization in Proteobacteria  

SciTech Connect (OSTI)

Bacteria can use branched-chain amino acids (ILV, i.e. isoleucine, leucine, valine) and fatty acids (FA) as sole carbon and energy sources convering ILV into acetyl-CoA, propanoyl-CoA and propionyl-CoA, respectively. In this work, we used the comparative genomic approach to identify candidate transcriptional factors and DNA motifs that control ILV and FA utilization pathways in proteobacteria. The metabolic regulons were characterized based on the identification and comparison of candidate transcription factor binding sites in groups of phylogenetically related genomes. The reconstructed ILV/FA regulatory network demonstrates considerable variability and involves six transcriptional factors from the MerR, TetR and GntR families binding to eleven distinct DNA motifs. The ILV degradation genes in gamma- and beta-proteobacteria are mainly regulated by anovel regulator from the MerR family (e.g., LiuR in Pseudomonas aeruginosa) (40 species), in addition, the TetR-type regulator LiuQ was identified in some beta-proteobacteria (8 species). Besides the core set of ILV utilization genes, the LiuR regulon in some lineages is expanded to include genes from other metabolic pathways, such as the glyoxylate shunt and glutamate synthase in the Shewanella species. The FA degradation genes are controlled by four regulators including FadR in gamma-proteobacteria (34 species), PsrA in gamma- and beta-proteobacteria (45 species), FadP in beta-proteobacteria (14 species), and LiuR orthologs in alpha-proteobacteria (22 species). The remarkable variability of the regulatory systems associated with the FA degradation pathway is discussed from the functional and evolutionary points of view.

Tetrazole acetic acid: Tautomers, conformers, and isomerization  

SciTech Connect (OSTI)

Monomers of (tetrazol-5-yl)-acetic acid (TAA) were obtained by sublimation of the crystalline compound and the resulting vapors were isolated in cryogenic nitrogen matrices at 13 K. The conformational and tautomeric composition of TAA in the matrix was characterized by infrared spectroscopy and vibrational calculations carried out at the B3LYP/6-311++G(d,p) level. TAA may adopt two tautomeric modifications, 1H- and 2H-, depending on the position of the annular hydrogen atom. Two-dimensional potential energy surfaces (PESs) of TAA were theoretically calculated at the MP2/6-311++G(d,p) level, for each tautomer. Four and six symmetry-unique minima were located on these PESs, for 1H- and 2H-TAA, respectively. The energetics of the detected minima was subsequently refined by calculations at the QCISD level. Two 1H- and three 2H-conformers fall within the 0–8 kJ mol{sup ?1} energy range and should be appreciably populated at the sublimation temperature (?330 K). Observation of only one conformer for each tautomer (1ccc and 2pcc) is explained in terms of calculated barriers to conformational rearrangements. All conformers with the cis O=COH moiety are separated by low barriers (less than 10 kJ mol{sup ?1}) and collapse to the most stable 1ccc (1H-) and 2pcc (2H-) forms during deposition of the matrix. On the trans O=COH surfaces, the relative energies are very high (between 12 and 27 kJ mol{sup ?1}). The trans forms are not thermally populated at the sublimation conditions and were not detected in matrices. One high-energy form in each tautomer, 1cct (1H-) and 2pct (2H-), was found to differ from the most stable form only by rotation of the OH group and separated from other forms by high barriers. This opened a perspective for their stabilization in a matrix. 1cct and 2pct were generated in the matrices selectively by means of narrow-band near-infrared (NIR) irradiations of the samples at 6920 and 6937 cm{sup ?1}, where the first OH stretching overtone vibrations of 1ccc and 2pcc occur. The reverse transformations could be induced by irradiations at 7010 and 7030 cm{sup ?1}, transforming 1cct and 2pct back to 1ccc and 2pcc, also selectively. Besides the NIR-induced transformations, the photogenerated 1cct and 2pct forms also decay in N{sub 2} matrices back to 1ccc and 2pcc spontaneously, with characteristic decay times of hours (1H) and tens of minutes (2H). The decay mechanism is rationalized in terms of the proton tunneling. In crystals, TAA exists exclusively as 1H-tautomer. By contrast, the tautomeric composition of the matrix-isolated monomers was found to consist of both 1H- and 2H-tautomers, in comparable amounts. A mechanistic discussion of the tautomerization process occurring during sublimation, accounting also for the observed minor decomposition of TAA leading to CO{sub 2} and 5-methyl-tetrazole, is proposed.

Formic acid decomposition on polycrystalline platinum and palladized platinum electrodes  

SciTech Connect (OSTI)

This is a comprehensive study in which a formic acid decomposition reaction is examined as a probe of catalytic properties of polycrystalline platinum and palladized platinum electrodes. The electrode potential varies in a broad range, and the reaction is carried out in perchloric acid and sulfuric acid solutions containing different concentrations of HCOOH. Analytical methods used to access the decomposition reaction are chronoamperometry and cyclic voltammetry. At very short times, the authors prove that only a negligible amount of surface CO is formed, and the CO unaffected decomposition reaction, leading to CO{sub 2} formation, can be interrogated. Surprisingly, the decomposition reaction displays Tafel behavior only in a very narrow potential range. This observation, made with both clean Pt and Pt/Pd electrodes, suggests that water-surface interactions, and/or (bi)sulfate-surface interactions, increase with increasing electrode potential and create a steric/electronic barrier for the decomposition of formic acid (and methanol). The authors therefore offer a pessimistic view about platinum as a universal material for heterogeneous catalysis applications involving rearrangements of organic molecules. Such rearrangements may only be fulfilled with a low electrochemical driving force, at least at room temperature, but at higher potentials, the electrode becomes deactivated due to the unique attributes of the double layer structure on the platinum electrode. The authors have also found that the deceleration of formic acid oxidation (to CO{sub 2}) is primarily due to CO chemisorption only at potentials overlapping with those from the hydrogen adsorption range, or not too positive from this range. At more positive potentials, the decay in formic acid decomposition is neither due to CO formation nor to solution mass transfer limitations. The presence of interfacial CO{sub 2} or adsorption of formic acid and/or formate anion, could account for the decay. Finally, a detailed analysis of kinetic isotherms involved in the two pathways, CO{sub 2} formation and CO chemisorption, is made and the mechanism of formic acid decomposition on platinum is discussed. The electrolyte anion effects involved in formic acid oxidation in HClO{sub 4} and in H{sub 2}SO{sub 4} solutions are also presented.
