Abstract
Alumina, silica or silica-alumina containing catalysts are manufactured by incorporating at least one active element selected from the metals of the groups V, VI and VIII or their compounds to a carrier, and then drying and activating. The carrier or the catalyst is shaped into extrudates and the latter are crushed to coarse particles.
