The selective decarboxylation/decarboxylation of fatty acids is a relatively new technique which emerged very recently [7]. The idea of the process is to selec­tively decarboxylate/decarbonylate fatty acids to n-1-carbon alkanes with the selectivity above 95%. It was shown that fatty acid conversion can be achieved at around 300oC without using hydrogen [8]. Moreover, the pressure of the process is around 2 MPa using typically argon or 5% vol. H2 in argon atmosphere, compared to HDO over Ni-Mo and Co-Mo catalysts, where pressure is around 3-8 MPa of hydrogen.
