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. The catalysts are preferably used in hydroisomerization and hydrocracking processes.
