Abstract
Abstract The conversion of hydrocarbons in the presence of hydrogen occurs under hydrocarbon conversion conditions in the presence of a subgroup of a certain class of metal-substituted semi-crystalline aluminosilicates which are synthetic and which are predominantly ordered in two directions, that is, which are laminar or have a layered or stacked sheet structure. The metal substituted for the aluminum in the trioctahedral sites is nickel, cobalt, or mixtures thereof. Hydrocarbon conversion catalysts are also claimed comprising the metal-substituted laminar 2:1 layer lattice aluminosilicate minerals containing in addition a hydrogenation component such as palladium. The catalysts are preferably used in hydroisomerization and hydrocracking processes.
