摘要： Method for producing C3H5(OH)3 and at least one of fatty acid methyl ester (FAME) and fatty acid ethyl ester (FAEE) includes mixing vegetable oils and animal fats, at least one of CH3OH and C2H5OH and at least one first catalyst to transesterify a portion of triglycerides and provide a first mixture. The first mixture is separated, with a first light phase being withdrawn and fed into a second mixer where it is mixed with at least one second catalyst to transesterify a further portion of the triglycerides to provide a second mixture. The second mixture is separated, with a second light phase being withdrawn and mixed with soapless C3H5(OH)3 to provide a dispersion which is separated by density difference. A phase containing at least one of raw FAME and raw FAEE is mixed with an aqueous acid, washed with water, with the water being expelled to provide FAME and FAEE product.

摘要： A process is disclosed for enzymatically degumming vegetable oil where the vegetable oil to be degummed is adjusted to a pH from 3 to 6 and is mixed with an aqueous enzyme solution, which contains one of the enzymes phospholipase A1, A2 or B. In a degumming reactor the enzymes are permitted to act on the oil at temperatures from 20.degree. to 90.degree. C. with stirring. Before or after a separation of the degummed oil a separation promoter or a solubilizer is added at temperatures from 20.degree. to 90.degree. C. to the liquid which has been withdrawn from the degumming reactor. A substantially sludgefree solution, which contains used enymes, is thus recovered and is recycled at least in part to a location preceding the degumming rector. The content of recycled used enzymes in the total amount of the enzymes dispersed in the oil is at least 10%.

摘要： Fatty acids and/or fatty acid derivatives as well as hydrogen, fresh catalyst and a dispersion which contains used catalyst are supplied to the hydrogenating means, which are operated at temperatures in the range from 100.degree. to 400.degree. C. and under pressures in the range from 20 to 400 bars to produce a product stream, which contains fatty alcohols and used catalyst. A part of the product stream is circulated. A first partial stream Is withdrawn at a controllable rate from the circulating stream and is passed through a separator. A product which is rich in fatty alcohol and a dispersion which contains used catalyst are separately delivered by the separator. The dispersion is recycled to the hydrogenating means. A second partial stream is withdrawn at a controllable rate from the circulating product stream. Used catalyst is separated from the second partial stream and is removed from the process. The rate at which used catalyst is fed to the hydrogenating means can be increased in that the rate of the second partial stream is decreased.

摘要： In producing C2-C4 olefins, in particular propylene, from an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, the educt mixture is reacted in a reactor on a catalyst to a reaction mixture comprising low-molecular olefins and gasoline hydrocarbons, which in a first separating device is separated into a mixture rich in C5− olefins, a mixture rich in C5+ gasoline hydrocarbons, and an aqueous phase. To increase the yield of propylene the mixture rich in C5+ gasoline hydrocarbons is supplied to a second separating device, in which the aromatics contained in the mixture are separated. The residual stream largely free from aromatics is at least partly recirculated to the reactor.
