A method is described for preparing a catalyst composition for processing high nitrogen-containing oils comprising a boron-containing crystalline material having the structure of zeolite ZSM-5, ZSM-11, ZSM-12, Beta or Nu-1. The sequential steps of synthesizing a boron-containing crystalline material having the structure of zeolite ZSM-5, ZSM-11, ZSM-12, Beta or Nu-1 are: drying the crystalline material at a temperature of from about ambient to less than about 170/sup 0/C; calcining the dried crystalline material in an oxygen- and water-free environment of anhydrous ammonia, anhydrous nitrogen, other anhydrous inert gases or a mixture thereof at a temperature of from about 200/sup 0/ to about 600/sup 0/C to minimize hydrolysis of boron in the boron-containing crystalline material; adsorbing ammonia on the calcined crystalline material; contacting the crystalline material with an ion-exchange solution at a pH of from about 7 to about 11; compositing the ion-exchange solution contacted crystalline material with an inorganic oxide material; drying the composite at a temperature of from about ambient to less than about 170/sup 0/C and calcining the dried composite at a temperature of from about 200/sup 0/ to about 600/sup 0/C.
