HGY Series Catalyst FCC catalyst
HGY series catalysts are characterized by maximizing gasoline yield and suitable for processing hydrotreated resid or VGO feedstock.
HGY series catalysts can increase yield and RON of gasoline, improve coke selectivity and bottom conversion, as well as metal resistance performance.
Aiming at increasing the gasoline yield, the proper arrangement of matrix and/or molecular sieve cracking ability and the structural dimensions of various pores are considered, and acid central density and acid strength of catalyst are adjusted properly. By means of increasing the specific surface of medium pores and large pores of matrix, strengthening the activity of matrix, and using RE exchanged ultra-stable Y-type molecular sieves with enough mesopores as active component, catalyst could achieve required heavy oil cracking capacity. The mesopores of RE exchanged ultra-stable molecular sieve can improve heavy oil macromolecules cracking ability, which is favorable for the diffusion of reaction products and reducing the second cracking of intermediate distillate, allowing catalyst with better gasoline selectivity and coke selectivity.
