Patent ID: 8394258

Claim:
Process for producing branched hydrocarbons, said process comprising the steps wherein a feedstock comprising at least one unsaturated compound selected from the group consisting of triglycerides, carboxylic acids having a carbon number C1-C38, esters of C1-C38 carboxylic acids with C1-C11 alcohols, esters of C1-C38 carboxylic acids with C12-C38 alcohols, natural waxes and dicarboxylic acids, is subjected to an isomerization step at a temperature from 150-350° C. and under a pressure of 0-5 MPa in the presence of isomerization catalyst, then a ketonisation step is carried out in the presence of metal oxide catalyst under a pressure from 0 to 10 MPa and at a temperature ranging from 100 to 500° C., and the ketonisation product is hydrodeoxygenated in the presence of a hydrodeoxygenation catalyst under a hydrogen pressure ranging from 0.1 to 20 MPa at a temperature ranging from 100 to 500° C.
