Conversion of isobutene to aromatics or polyisobutylene with modified gamma alumina composition

摘要

A novel aluminous composition prepared by impregnating porous gamma alumina with aluminum hydride and subsequently heating the impregnated alumina to a temperature of from about 300 DEG C. to about 900 DEG C. in a non-oxidizing environment. The composition is useful as a catalyst in reactions catalyzed by acid catalysts.
