ABSTRACT A process for the synthesis and preparation of a catalyst support having a relatively high concentration of pores of uniformly large diameter, high surface area and pore volume comprising dispersing an aluminum halide salt in an aqueous or alcohol medium in molar ratio of water:aluminum halide or alcohol:aluminum halide ranging from about 15:1 to about 30:1 and, while maintaining the temperature within a range of from about 30° F. to about 100°F., adding olefin oxide in molar ratio of olefin oxide:halide of from about 0.3:1 to about 2.0:1 while maintaining a pH in the range of from about 5-8 to effect removal of the halide from solution and form a sol, introducing the sol into a mineral oil in volume ratio of mineral oil:sol of from about 5:1 to about 20:1, and, while maintaining a temperature ranging from about 75°F. to about 150°F., agitating sufficiently to form spheres which are transformed from sol into gel, aging the gel spheres while in contact with syneresis liquid for a period sufficient to increase the strength of the gel without significant adverse shrinkage of the size of the pores developed in the gel washing, drying, calcining, and then recovering a product comprising particles ranging about 1/8 inch average particle size diameter, and smaller. The resulting catalysts possess improved catalytic activity and selectivity for the hydroconversion of the 1050°F+ materials of the heavy feeds and residua.
