ABSTRACT:
Novel, composited silica catalyst supports suitable for commercial utilization, which may typically have an average pore diameter in the range of about 100 to about 5000 Angstroms, an advantageously high surface area in the range of about 30 to about 125 square meters per gram and a bulk density in the range of about 0.3 to about 0.6 gram per cubic centimeter, are made by mixing amorphous silica powder having an average particle size in the range of about 10 to about 50 millimicrons with a medium suitable for binding the silica powder. The mixture of silica powder and binder is formed into suitable, macrosized catalyst support shapes by press molding, extrusion, tableting and like forming means. The shaped mixture of silica powder and binder is calcined to form the novel silica catalyst supports.
