Abstract
A surface-inactivated catalyst composition comprising acidic porous crystalline material, e.g., ZSM-23, having active internal Bronsted acid sites and containing surface-inactivating material having a boron to nitrogen bond is prepared by contacting the surface with aqueous ammonia borane solution. The catalyst may be used for organic compound conversion, e.g., oligomerization of lower olefins to produce distillate boiling range materials having reduced methyl branching and increased cetane number.
