Abstract: This invention provides processes for producing fuel, particularly transportation fuel, from biological material, e.g., lipid material. One aspect of the invention involves hydroprocessing a feedstock in a hydroprocessing zone that is maintained at conditions that promote the efficiency of converting the lipid-containing feedstock into transportation fuel. Such conditions include one or more of maintaining CO content of the hydroprocessing zone at a predetermined amount and recycling or providing a hydrogen-containing gas to the hydroprocessing zone that has been treated to remove CO.

Abstract: A comprehensive fuel additive for gasoline, diesel and ultra low sulfur diesel fuels intended to improve engine combustion efficiency, improve diesel fuel cetane levels, improve diesel and ultra low sulfur diesel fuel lubricity, reduce engine component friction, reduce engine deposit buildup, reduce gasoline and diesel fuel bio-contamination and reduce pollutant exhaust emissions produced by gasoline and diesel fuel powered internal combustion engines. The present invention further provides a fuel additive that does not increase the sulfur level of diesel fuel beyond 15 ppm.
Abstract: This invention relates to processes for the production of a fuel composition from a feedstock that comprises lipid material (e.g., bio-material) and mineral oil. The processes can be carried out without producing a significant mount of undesirable side reactions such as cracking, polymerization, and aromatization, which can be an undesirable consequence of large heats of reaction. As a result, the invention provides for the production of a product that is relatively high in quality, and catalyst used in the processes is not adversely affected to any significant extent.

Abstract: Embodiments of the present invention are directed toward systems and methods of providing a low-emissions diesel fuel for use in cold climates. Such fuels may be prepared by a Fischer-Tropsch process and include a pour point depressant. Furthermore, the fuel is used in conjunction with a heated fuel delivery system so that low cloud points are not necessary. Fuels prepared according to embodiments of the present invention may be produced in higher yields than otherwise possible because a higher paraffin wax content can be tolerated, thus obviating the need to remove or exclude the wax. These fuels are characterized by a sulfur content less than 1 ppm, a cetane number greater than 60, an aromatics content less than 1 wt %, and a difference between the cloud and pour points that is greater than about 5° C. The present fuel may be prepared by a Fischer-Tropsch synthesis from any number of carbon-containing sources such natural gas, coal, petroleum products, and combinations thereof.
Abstract: Methods for recovery of concentrates of lubricating compounds from vegetable and animal oils, fats and greases that allow separation of triglycerides, from components with higher lubricity or enrichment protocols that increase the concentration of high lubricity compounds in the triglyceride. The triglycerides are transesterified with a lower alcohol to produce alkyl esters. Following the conversion process the esters are separated from high molecular weight high lubricity compounds by distillation. The esters have some lubricity and may be sold as pollution reducing fuel components. The high boiling point compounds that are the residues of distillation, however, can contribute significant lubricity and may be used widely in lubricant applications or added to petroleum fuels to decrease friction.
