ABSTRACT:
A composition of matter comprising alumina as the major component and silica as a minor component is prepared by a process comprising sequential addition of solutions of aluminum salt and alkali metal aluminate, addition of a solution of alkali metal silicate to dispersed alumina hydrogel and heating formed alumina-silica hydrogel under dehydrating conditions. The thus prepared composition of matter, optionally promoted with at least one transition metal compound, can be used as a catalyst for hydrotreating substantially liquid hydrocarbon-containing feed streams which also contain sulfur and metal compounds as impurities.
