Abstract: A method for producing ketones includes a) providing a feedstock of biological origin having fatty acids and/or fatty acid derivatives having an average chain length of 24 C-atoms or less; b) subjecting the feedstock to a catalytic ketonization reaction in the presence of aK2O/TiO2-catalyst; and c) obtaining from the ketonization reaction a product stream having ketones, which ketones have a longer average hydrocarbon chain length than the average hydrocarbon chain length in the feedstock, wherein step b) is carried out directly on the feedstock and in the presence of the K2O/TiO2-catalyst as the sole catalyst applied in the ketonization reaction.

Abstract: The present invention relates to a method for conversion of levulinic acid and to a hydrocarbon composition obtainable by the method. The method comprises a step of providing a feedstock, a conversion step of subjecting the feedstock to a C—C coupling reaction and a hydrotreatment, and a hydrodeoxygenation step. The content of levulinic acid dimer derivatives having 4 oxygen atoms subjected to the hydrodeoxygenation step is 20 wt.-% or more.
