CATALYST COMPRISING SILICA SUPPORTED BY BOEHMITE SURFACE

Title:

CATALYST COMPRISING SILICA SUPPORTED BY BOEHMITE SURFACE

Document Type and Number:

Japanese Patent JPS62160139

Kind Code:

A

Abstract:

Useful cracking catalysts and catalyst supports comprising silica supported on a boehmite-like surface are prepared by compositing particles of silica or hydrated silica with particles of porous boehmite and subjecting the resulting composite to high temperature steaming at a temperature of at least about 600°C for a time sufficient to disperse at least a portion of the silica over the boehmite surface as the boehmite converts to y-A1₂0₃. The silica wets, spreads out and reacts with the surface hydroxyl groups of the transforming boehmite.
