Abstract: A PROCESS FOR PRODUCING CATALYSTS WITH LARGER AVERAGE PORE DIAMETERS WHICH COMPRISES (A) FORMING A HYDROGEL COMPRISING AT LEAST ONE INORGANIC OXIDE, (B) ADDING A DETERGENT TO THE HYDROGEL, AND (C) CARRYING OUT AT LEAST PART OF THE DRYING OF THE HYDROGEL AFTER THE DETERGENT IS ADDED TO THE HYDROGEL. PREFERABLY THE DETERGENT IS A NONIONIC HIGH MOLECULAR WEIGHT DETERGENT COMPOSED ONLY OF CARBON, HYDROGEN, AND OXYGEN.
