  • Method for preparing fatty acid esters with alcohol recycling
    Patent number: 8076498
    Abstract: A method produces fatty acid esters by transesterification of fats and oils with the aid of an alcohol, at a high pressure and temperature. Unreacted alcohol is separated inline from the reaction mixture and continuously recycled into the transesterification process. The separation is performed by obtaining a vapour phase and higher density phases of the reaction mixture and concentrating the alcohol in the vapour phase.
    Type: Grant

    Date of Patent: December 13, 2011

  • Method for producing biodiesel using an immobilised catalyst
    Patent number: 8067624
    Abstract: A method produces a fatty acid alkylester by transesterification of a fat or oil and an alcohol. The reaction is catalysed by a heterogeneous catalyst immobilized in a tubular reactor at a temperature between 260 and 420° C. and at a pressure higher than 5 bar. A mixture of the fat or oil and the alcohol is led in a continuous flow through the tubular reactor. The catalyst is preferably a metal oxide or a metal carbonate including an alkaline earth metal. The reaction takes place at reduced residence times and contact times compared to the prior art.
