Abstract

Abstract : An efficient H-ZSM-5 zeolite interface with optimized surface diffusion barriers was tailored by passivating the hydroxyl-group defects at surfaces or near pore mouths, resulting in significant improvement in catalytic cracking performances. Abstract : An efficient zeolite interface with optimized surface barriers was tailored by passivating the hydroxyl-group defects at surfaces or near pore mouths. The surface permeability of the modified zeolite was almost 90% greater than that of the pristine one, leading to remarkable improvements in C=2–3 selectivity and an anti-inactivation rate of 75% for the catalytic cracking reaction.
