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.

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