ABSTRACT:
A novel shape selective metal catalyst can be prepared by incorporating a metallic catalyst component such as platinum, palladium, or nickel into a member of a novel class of zeolites, said zeolites characterized by a silica to alumina mole ratio of at least 12 and a constraint index within the approximate range of 1 to 12, and then reducing the combined metal-zeolite in the presence of unsaturated hydrocarbon compounds with or without hydrogen at high temperatures.
