Abstract
A surface-inactive shape selective metallosilicate catalyst, useful for the conversion of lower molecular weight olefins to liquid hydrocarbons such as gasoline, distillate, and high viscosity lube oils, is prepared by a process comprising forming a silica shell on a metallosilicate core by crystallizing silica in the presence of fluoride ion onto the surface of the core.
