Abstract�� The inter diffusion characteristics of benzene and isopropyl benzene in zeolite catalysts were studied by the simple and practical method.Based on measuring the different concentrations of diffusion solute in all time,the inter coefficients of all diffusion solute in zeolite catalysts were correlated in terms of rational mathematical model and least square fitting.This can supply fundamental data for the industrial simulation of benzene alkylation.
