The present invention provides a method for producing a fatty acid ester inexpensively and efficiently by reacting a lipase or an intact mircroorganism containing a lipase, an oil and fat, and a linear lower alcohol in a system containing little or no solvent in the presence of water. The intact microorganism has not been treated with a solvent or the like, and is used as such, so that a fatty acid ester can be prepared in a simple manner. An oil and fat, a natural oil and fat such as a vegetable oil and fat, an animal oil and fat, as well as a waste oil thereof can be used. According to the method of the present invention, a reaction proceeds even in the presence of water, so that waste oils containing a large amount of water can be used as a raw material. Therefore, the waste oil to be dumped into the environment can be recycled, and a biodiesel fuel, which hardly pollutes the environment, can be provided at the same time.

A process has been developed for producing diesel boiling range fuel from renewable feedstocks such as plant oils and animal oils, fats, and greases. The process involves treating a renewable feedstock by hydrogenating and deoxygenating i.e. decarboxylating, decarbonylating, and/or hydrodeoxygenating to provide a hydrocarbon fraction useful as a diesel boiling range fuel or diesel boiling range fuel blending component. If desired, the hydrocarbon fraction can be isomerized to improve cold flow properties. A portion of the hydrogenated and deoxygenated feedstock is selectively separated and then recycled to the treatment zone to increase the hydrogen solubility of the reaction mixture.

Alkyl esters of fatty acids, and high purity glycerin, are produced using a process comprising a set of transesterification reactions between a vegetable or animal oil and an aliphatic monoalcohol employing a heterogeneous catalyst, for example based on zinc aluminate, the water content in the reaction medium being controlled to a value that is below a given limiting value.

A process has been developed for producing a diesel boiling point range product and an aviation boiling point range product from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction which is then isomerized and selectively cracked to form the diesel boiling point range product and the aviation boiling point range product. A portion of the diesel boiling point range product, aviation boiling point range product, naphtha product, LPG, or any combination thereof can be optionally used as a rectification agent in the selective hot high pressure hydrogen stripper to decrease the amount of product carried in the stripper overhead.

A process for thermally cracking virgin or waste animal oils (tallow) into a diesel fuel product is provided. The thermal cracking process uses low cracking temperatures from 625 to 725° F. with ambient pressure and no catalyst to generate a column distilled fraction of diesel fuel mixed with light ends, the light ends being flashed off to produce a high quality #2 diesel fuel suitable for road use. The oils to be distilled are exposed to a heat exchanger with a skin temperature of 1750° F. generated by hot air produced by a thermal oxidizer. This results in the processed product going from a liquid to a liguid/gas during the pump around residence time of 3 to 5 seconds before moving up a distillation column as a gas to the desired finished product.
