Abstract
Abstract Hydrocarbons are converted in the presence of catalysts comprising at least a catalytic amount of a crystalline aluminosilicate zeolite thermally activated by heating to a temperature in excess of about 900o F. in a period not substantially in excess of about 30 minutes. Such catalysts can comprise other active hydrocarbon conversion components such as the metals, oxides and sulfides of Groups II-B, IV-B, V-B, VI-B and VIII. These compositions are particularly effective for catalytic cracking, hydrorefining, hydrogenation, hydrocracking, isomerization and the like.
