摘要： The present invention relates to an improved process for treating lipid feedstocks such as spent vegetable oils and low-value animal fats for biofuel production. In particular, the invention relates to methods for providing an advantageous feedstock for production of hydrocarbon biofuels via hydrodeoxygenation.

摘要： A process for producing crude biodiesel from renewable feedstocks (such as fats, oils, and greases) containing unsaponifiable materials; purifying the crude biodiesel through a purification process; recovering a purified biodiesel distillate stream and a less volatile biodiesel residue stream; and further recovering valuable chemicals from the biodiesel residue. Specifically, the present technology relates to the concentration of valuable chemicals in the biodiesel residue product of biodiesel production and the subsequent recovery of these valuable chemicals. The process may further include the conversion of the biodiesel residue into diesel range hydrocarbons using hydrodeoxygenation and the subsequent purification of the hydrocarbon fraction produced thereby.

摘要： Methods, processes, apparatus, equipment and systems are disclosed for converting carboxylic acids into esters by esterification with alcohol and a dual catalyst. The method combines a homogenous and heterogeneous catalyst in one or more reactors to increase the conversion of carboxylic acids compared to using a homogenous and/or heterogeneous catalyst independently. The invention converts free fatty acids into esters by esterification with alcohol and a dual catalyst such that the reaction mixture contains sufficiently low free fatty acids and the amount of free fatty acids in the product stream leaving the process remains stable over time.

摘要： The invention relates to renewable hydrocarbons, and more particularly to biomass-based diesel fuel produced in a process including hydrodeoxygenation (HDO) of phenolic lipids. The process may generally include combining a phenolic lipid and a hydrocarbon diluent to provide a hydrocarbon-diluted phenolic lipid then subjecting the hydrocarbon-diluted phenolic lipid to hydrodeoxygenation in a reactor to provide a reactor effluent including a hydrodeoxygenated phenolic lipid. The hydrodeoxygenated phenolic lipid is separated from the reactor effluent.

摘要： An improved method for removal of contaminants from low-value and waste fats and oils for the purpose of hydrodeoxygenation into diesel boiling range hydrocarbons. The method includes removing organically bound contaminants from fats, oils, and greases (FOG) by adding water to a contaminated FOG stream, subjecting the mixture to heat, and mixing to promote reaction between the water and the FOG. Then, separating a reacted FOG from the contaminants. The reacted FOG will result in reduced organically bound chlorine contaminants.

摘要： Methods and apparatus for economically producing a biodiesel product from feedstocks. Some embodiments comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The free fatty acid refining process may include introducing the feedstock to glycerolysis to obtain a glycerolysis product then stripping the glycerolysis product to produce a fatty acid distillate and a stripped feedstock. The fatty acid distillate is recycled to the glycerolysis process to create more higher-molecular weight glycerides and the stripped feedstock (mostly di- and tri-glycerides) proceeds to transesterification to make biodiesel.

摘要： Methods and devices for economically producing a purified biodiesel product from feedstocks. Some embodiments of the methods comprise using at least one of a crude feedstock pretreatment process and a free fatty acid refining process prior to transesterification and the formation of crude biodiesel and glycerin. The crude biodiesel is then subjected to at least one biodiesel refining process which, in conjunction with feedstock pretreatment and free fatty acid refining produces a purified biodiesel product that meets multiple commercial specifications. A wide variety of feedstocks may be used to make biodiesel that otherwise would not meet the same commercial specifications, including corn oil, used cooking oil, poultry fats, fatty acid distillates, pennycress oil, and algal oils. The combination of feedstock refining and biodiesel refining processes is necessary to reduce problems associated with feedstocks having waxes, high free fatty acid levels, unacceptable color, high unsaponifiables levels, and high sulfur levels.
