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 ares 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, raising the temperature of the solution to substantially ambient temperature or higher to form a gel which separates from its syneresis liquid, aging the gel while in contact with syneresis liquid for a period of at least 6 hours, separating the gel from the syneresis liquid, and then washing, drying, calcining, and then recovering a product. The resulting catalyst support when impregnated with a catalyst provides catalysts which include Group VIB and Group VIII metals, having certain critical ranges of physical characteristics inclusive of large uniform pore sizes, these having been shown to possess improved catalytic activity and selectivity for the hydroconversion of the 1050°F.+ materials of the heavy feeds and residua.
