Abstract
The present invention provides a method for simultaneous production of components suitable for production of base oil and fuel components. In the method a feedstock comprising fatty acids and/or fatty acid esters is entered into a reaction zone and subjected to a ketonisation reaction in the presence of a dual catalyst system. This system is configured to perform a ketonisation reaction and a hydrotreatment reaction, under hydrogen pressure. Subsequently ketones are obtained.
