    摘要: Disclosed is an improved process for the production of fatty acid lower alkyl esters according to formula (I) R1CO—OR2  (I) in which R1CO represents a linear or branched acyl moiety having from about 6 to about 22 carbon atoms and 0 to 6 double bonds and wherein R2 is a linear or branched alkyl moiety having 1 to 6 carbon atoms, by transesterification of triglycerides or fatty acid esters using C1-C6 aliphatic alcohols, which includes the steps of (a) providing an aqueous mixture of aliphatic C1-C6 alcohol by fermenting in a first reactor a carbon source comprising carbohydrates and/or glycerol produce a fermentation broth comprising said aliphatic C1-C6 alcohol, (b) providing in a second reactor a triglyceride and/or an ester of a fatty acid, together with a biocatalyst capable of effecting a transesterification reaction, (c) transferring said aqueous aliphatic C1-C6 alcohol mixture obtained from said first reactor into said second reactor to provide a two-phase system, and (d) effecting the transesterification reaction to produce said fatty acid lower alkyl ester and a glycerol- or alcohol-containing aqueous phase. The products thus obtained are particularly useful as components of the fuel known as biodiesel.

    摘要: The disclosed invention relates to a countercurrent process for the continuous esterification of C1-22 (fatty) acids with C1-10 monoalkanols, C2-5 di- or trialkanols or mixtures thereof in the liquid phase in the presence of heterogeneous catalysts in a preliminary reactor (1) and in a reaction column (3), characterized in that the reaction column (3) is preceded by the preliminary reactor (1) and a separation unit (2) for the purpose of reducing the viscosity of the reaction mixture and removing the water of reaction from the system via a separation unit (2) to displace the reaction equilibrium before the reaction column (3). A further aspect of the invention concerns feeding nitrogen in at the lowermost plate of the reaction column (3) in order to increase the vapour load in the lower part of the reaction column.

    摘要: The invention relates firstly to a discontinuous process for conducting a heterogeneously catalyzed reaction taking place at elevated temperature, in which heat-sensitive products are formed, a heat transfer unit (4) different from the reactor (1) being used for heating and a fixed-bed catalyst (3) being used as the catalyst and the reaction mixture being continuously circulated in succession through the catalyst (3) and then through the heat transfer unit (4). The problem to be solved in this process is to avoid losses of catalyst and product and to shorten the batch time and, optionally, the reaction time in accordance with German patent applications P 38 13 612.0 and P 38 26 320.3. The invention also relates to a plant for the discontinuous heterogeneously catalyzed production of heat-sensitive products at elevated temperature comprising a reactor (1), characterized by a heat transfer unit (4) arranged outside and connected to the reactor (1), a catalyst container (3) containing a fixed-bed catalyst preceding the heat transfer unit and a pump (2) for continuously circulating the reaction mixture in succession through the catalyst (3) and then through the heat transfer unit (4).
