A catalyst composition which comprises a crystalline metallosilicate having the structure of zeolite Beta, phosphor and a matrix that is substantially free of crystalline aluminum phosphate which has improved resistance to steam deactivation which has higher cracking activity than analogous catalysts prepared without phosphorus. The crystalline metallosilicate be used in the as-synthesized form or in the calcined form. included is the method to produce the catalyst composition and methods for the use of catalysts prepared by the present method in organic conversion processes. Specific embodiments of the invention involve various techniques for preparation of catalyst containing phosphorus and crystalline metallosilicates having the structure of zeolite Beta. Catalysts prepared according to the method of this invention are useful for organic compound, e.g., hydrocarbon compound, conversion processes. Organic compound conversion processes include cracking, hydrocracking, and transalkylation, among others.
