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.
