  • Patent number: 6262313
    Abstract: This invention provides a method for thermally converting volatile fatty acid (VFA) salts to ketones by mixing dry calcium salts of VFAs with hot heat transfer agent in an evacuated container, thereby causing thermal decomposition of the calcium salts of VFAs to form ketone-containing vapor and calcium carbonate; and separating the ketone-containing vapor from the calcium carbonate and heat transfer agent by condensing a mixture of ketones from the ketone-containing vapor. This invention also provides a process for conversion of VFA salts, produced by anaerobic fermentation of cellulosic biomass, into liquid fuels, volatile fatty acids, aldehydes, alcohols, and lactic acid.

  • Publication number: 20010005956
    Abstract: A polymeric fuel additive, a method of making the additive, and a fuel containing the additive are disclosed. The additive is prepared by isothermally mixing an ethoxylated alcohol and an amide, wherein the ethoxylated alcohol comprises at least about 75 weight percent of at least one linear, straight-chain alcohol having a hydrocarbon chain length of about nine to about fifteen carbon atoms, and wherein the amide is formed by reacting an alcohol amine with an equimolar amount of an alkyl ester of a fatty acid or derivative. The alcohol/amide product is isothermally mixed with a substantially equimolar amount of an ethoxylated fatty acid having a hydrocarbon chain length of about nine to about fifteen carbon atoms to produce the polymeric additive. The inventive method is carried out with gentle mixing so as to avoid molecular degradation of the additive.
