Title: Utilization of selected biorenewable resources: solubilization of lignocellulosics and conjugation of soybean oil

Abstract

In recent years, concern has risen over the use of fossil fuels due to their contribution to global warming, and to our dependence on imports of petroleum from nations that could pose a threat to national security. As a result, it has become increasingly important to develop technologies to replace fossil fuel based products with biorenewable alternatives. In this thesis nearly quantitative solubilization of lignocellulosic materials using phosphite esters has been realized, and is presented as a potential pretreatment for production of fermentable sugars for use in manufacturing commodity chemicals, specifically ethanol. Water solubilization of lignocellulosics using phosphite esters will enhance digestibility by disrupting the lignocellulose structure, changing cellulose morphology, and cleaving some glycosidic bonds. In a second project, soybean oil, which contains un-conjugated polyunsaturated fatty acid esters, is isomerized into oil containing conjugated polyunsaturates. The process is carried out under photochemical conditions using iodine as a catalyst in a hexanes solution to achieve 99% conjugation. The resulting conjugated soybean oil is demonstrated to have enhanced drying properties for use in alkyd resins.

  • Soybean oil is an abundant and renewable resource through annual crop production. The replacement of paraffin oil with soybean oil in agricultural adjuvants would create an additional market for surplus soybeans and help alleviate dependence on non-renewable petroleum oil. Field and laboratory experiments were conducted to compare effects of a petroleum oil-emulsifier blend (POC) and a soybean oil-emulsifier blend (SBOC) as adjuvants for postemergence herbicides. In field experiments, little difference was observed between POC and SBOC in the ability to enhance control of velvetleaf (Abutilon theophrasti Medik.) with 0.6 or 1.1 kg/ha bentazon (3-(1-methylethyl)-(1H)-2,1,3-benzothiadiazin-4(3H)-one 2,2-dioxide). Control of giant foxtail (Setariamore » faberi Herrm.) with 0.1 kg/ha sethoxydim )2-(1-(ethoxyimino)butyl)-5-(2-(ethylthio)propyl)-3-hydroxy-2-cyclohexen-1-one) was enhanced more by POC than by SBOC. The effects of adjuvants and relative humidity (RH) on absorption, translocation, and metabolism of the methyl ester of /sup 14/C-haloxyfop )2-(4-((3-chloro-5-(trifluoromethyl)-2-pyridinyl)oxy)phenoxy)propanoic acid) in corn (Zea mays L.) were investigated. Addition of 1.0% (v/v) POC to the treatment solution resulted in greater foliar absorption and translocation of /sup 14/C than addition of 1.0% (v/v) SBOC.« less
  • The objective of this study is to provide a broad framework of understanding of the effect of single and mixed alkanes having the same equivalent alkane carbon number (EACN) on phenomena arising from the mixing of a surfactant, brine, oil and in some cases a cosurfactant, and from the use of a surfactant slug for tertiary oil recovery. Single and mixed alkanes of identical EACN, when used as the oil component in surfactant systems containing 5%TRS 10-410, 3% isobutanol, brine and oil, produce systems with the same phase and coalescence behavior. As the EACN of oil increases, the optimal salinitymore » increases linearly, the solubilization parameter at optimal salinity decreases and the salinity range in which the system exhibits three phases increases. Studies revealed that maximum oil recovery is obtained at the optimal salinity of the surfactant formulation. The desirable conditions for maximum oil recovery were found to be as follows: the surfactant/alcohol slug should form a system of ultralow interfacial tension, should have a wide range of three-phase salinity, a high solubilization capacity and a rapid separation of the macroemulsion into three phases, and should consist of an alcohol with relatively low partitioning in brine or oil. It is shown that the Schulman-Bowcott titration curve to obtain a clear microemulsion of a sodium dodecyl sulfate, n-Hexanol, water and alkane system goes through a minimum at a specific alkane content. The slope of the curve is used to characterize mixtures of alkanes according to their EACN. Only a slight increase in the alcohol partitioning into the oil phase is observed with an increase in the EACN. The titration curve is also used to estimate pyrene partitioning in the interface and oil phase of a W/O microemulsion. Consequently, pyrene fluorescence can be used to estimate the partitioning of n-Hexanol in the interface and oil phase.« less
  • This study presents the design of a system for on-farm production of soybean oil for use as a fuel in compression ignition engines. The soybean oil production system consists of a heat exchanger to heat the beans with the exhaust gas of an engine, a screw press and a system for water degumming and drying the expressed crude oil. Optimum parameters of the oil production system were found. The rheological properties of soybean oil, ester of soybean oil and blends of the above with diesel fuel and diesel fuel additives are given. Data on soybean temperature, outlet gas temperature andmore » thermal efficiency were obtained from a developed mathematical model of the heat exchanger. Chemical analyses show that crude oil from the press is similar to that of commercially degummed oil. The degumming process is not needed for the crude oil to be used as a fuel in compression ignition engines. Rheological properties of the soybean oil and soybean oil diesel fuel mixture show that the fluids have viscosities of time independent characteristics and are Newtonian fluids. Diesel fuel additives having low viscosities can be used to lower the viscosity of soybean oil and blends with diesel fuel but the effect is insignificant.« less
  • Materials management is an integrative approach to control the flow of production materials. This dissertation focused on the public utilities industry and its practices in the materials management area. Major emphasis of this research was to 1) define the state-of-the-art of materials management within the gas and electric utilities in Texas, 2) determine its impact on the corporate structure, and 3) identify opportunities for materials management in the future of the Texas utilities industry. The major thrust of this research was to analyze the current status of materials management utilization within the industry. This was accomplished by examining the relationshipsmore » of selected demographic variables with companies' materials management posture. The materials management concept exists in varying stages of development in the gas and electric utility industry in Texas. Some firms classified as nonpracticing may in fact be utilizing materials management at a very early stage in development within the organization. Findings showed a trend toward the gaining acceptance of the materials management concept.« less
  • This study was developed through a synthesis and review of literature and research related to the current status of job satisfaction, energy resources, and perceptions of how energy is utilized in the manufacturing work environment. This synthesis and review revolved around several proven contributing factors of job satisfaction, such as age, education, and challenge from work itself. Quality of work life programs and their components are discussed in relation to their impact on job satisfaction. The nature of energy resource utilization is traced back through history with an emphasis on the limitations of current resources and options for the future.more » The review highlights the current debate over what should be the future path of energy resource development. The concept of satisfaction of human needs is reviewed and related to job satisfaction and energy resources. The purpose of this research study was to contribute to the understanding of how perceptions of energy resources relate to job satisfaction. Results of the study indicated that there were no significant differences between an individual's energy resource consciousness and perceptions of energy utilization in the work place, energy resource consciousness and job satisfaction, and job satisfaction and perceptions of energy utilization in the workplace.« less
