Purification of glycerin

A process for purifying glycerin recovered as a byproduct of biodiesel production comprises heating a glycerin effluent stream containing a low molecular weight alcohol, water and fatty acid esters of the low molecular weight alcohol to cause transesterification of the fatty acid esters to glycerides and additional low molecular weight alcohol. The reaction mixture is sparged with nitrogen to help remove water and low molecular weight alcohol, which drives the transesterification reaction towards glyceride formation. A wash water stream may also be added to the recovered glycerin stream from biodiesel production. Either before or following the transesterification reaction, an oil layer can be separated from the recovered glycerin stream by reducing the pH of the stream to below 7. Following separation of the oil layer and transesterification the glycerin stream is flash distilled to separate glycerin from water, salts, and glycerides.

Process for producing biodiesel, lubricants, and fuel and lubricant additives in a critical fluid medium

A process for producing alkyl esters useful in biofuels and lubricants by transesterifying glyceride- or esterifying free fatty acid-containing substances in a single critical phase medium is disclosed. The critical phase medium provides increased reaction rates, decreases the loss of catalyst or catalyst activity and improves the overall yield of desired product. The process involves the steps of dissolving an input glyceride- or free fatty acid-containing substance with an alcohol or water into a critical fluid medium; reacting the glyceride- or free fatty acid-containing substance with the alcohol or water input over either a solid or liquid acidic or basic catalyst and sequentially separating the products from each other and from the critical fluid medium, which critical fluid medium can then be recycled back in the process. The process significantly reduces the cost of producing additives or alternatives to automotive fuels and lubricants utilizing inexpensive glyceride- or free fatty acid-containing substances, such as animal fats, vegetable oils, rendered fats, and restaurant grease.

Process for preparing vegetable oil fractions rich in non-tocolic, high-melting, unsaponifiable matter

A vegetable oil fraction rich in non-tocolic, high-melting, unsaponifiable matter is prepared by the following steps: A vegetable oil having a slip melting point of not more thatn 30° C. and a content of unsaponifiable matter of at least 0.5% by weight is hydrogenated to fully saturate the fatty acids of the glycerides and to reach a slip melting point of at least 57° C. To the hydrogenated oil is added from 1 to 75% by weight of the unhydrogenated starting oil or another oil having a slip melting point of not more than 30° C. in order to act as a carrier and vehicle for the unsaponifiable matter. Then, a solvent is added to the oil mixture in a ratio between oil and solvent from 1:2 to 1:20, and the mixture is heated to transparency. The oil / -solvent-mixture is cooled in one or more steps to a final temperature in the range from −35 to +30° C., and the precipitated high-melting fraction(s) is (are) filtered off. The filtrate is desolventised, leaving a fraction rich in unsaponifiable matter. By this process very high concentrations of in particular the non-tocolic, higher melting unsaponifiables can be achieved, and the composition of the glyceridic part of the enriched fraction can betailored to specific applications. Also, a novel blood cholesterol-lowering effect of the unsaponifiable constituents from shea butter has been found.

Production of biodiesel and glycerin from high free fatty acid feedstocks

A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterfication process, may proceed by the addition of a mineral or an organic acid.

Extraction solvents derived from oil for alcohol removal in extractive fermentation

In an alcohol fermentation process, oil derived from biomass is chemically converted into an extractant available for in situ removal of a product alcohol such as butanol from a fermentation broth. The glycerides in the oil can be chemically converted into a reaction product, such as fatty acids, fatty alcohols, fatty amides, fatty acid methyl esters, fatty acid glycol esters, and hydroxylated triglycerides, and mixtures thereof, which forms a fermentation product extractant having a partition coefficient for a product alcohol greater than a partition coefficient of the oil of the biomass for the product alcohol. Oil derived from a feedstock of an alcohol fermentation process can be chemically converting into the fermentation product extractant. The oil can be separated from the feedstock prior to the feedstock being fed to a fermentation vessel, and the separated oil can be chemically converted to a fermentation product extractant, which can then contacted with a fermentation product comprising a product alcohol, whereby the product alcohol is separated from the fermentation product.
