Abstract
Amorphous, substantially spherical silica particles obtained by acidic hydrolysis of substantially spherical synthetic crystalline calcium silicates having a size of from 20 to 120 microns are coated with a layer comprising silica and alumina. The silica particles obtained may be directly employed as catalysts for the oligomerization of olefins and, having been loaded with platinum, as hydrocracking catalysts.
