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 ketonization reaction in the presence of a dual catalyst system. This system is configured to perform a ketonization reaction and a hydrotreatment reaction, under hydrogen pressure. Subsequently ketones are obtained.
Claims11
A dual catalyst system configured to perform a ketonisation reaction and a hydrotreatment reaction simultaneously, the dual catalyst system comprising:
- a metal oxide ketonisation catalyst in which the metal is selected from the group consisting of Na, Mg, K, Ca, Sc, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Ti, Y, Zr, Mo, Rh, Cd, Sn, La, Pb, Bi, Ti, V and other rare earth metals and any combination thereof;
- and
- a metal hydrotreatment catalyst wherein the metal is selected from the group consisting of Fe, Pd, Pt, Ni, Mo, Co, Ru, Rh, W and any combination thereof;
- wherein the metal oxide ketonisation catalyst and the metal hydrotreatment catalyst are combined in a single catalyst material.
