Abstract
Hydrocarbon conversion methods employing unique catalyst compositions exhibiting improved conversion characteristics particularly as regards denitrogenation and/or cracking selectivity to predetermined boiling range products involve the use of a catalytic combination of zeolitic aluminosilicates, alumina, and at least one of the metals, oxides and sulfides of Periodic Groups VI and VIII, prepared by the method including the steps of thermally activating at least a major portion of the alumina at a temperature of at least about 600.degree. F prior to combination with both the aluminosilicate and the hydrogenation component, forming an aggregate from an intimate admixture of the alumina, aluminosilicate and hydrogenation component and thermally activating the resultant aggregate. Midbarrel hydrocracking processes of higher selectivity and superior denitrogenation methods are described.
