摘要：

The performance of composite spherical or cylindrical single pellets containing ZSM-5 particles uniformly distributed in amorphous silica-alumina for catalytic cracking is examined experimentally and theoretically. The cracking of n-hexane over composite pellets is employed as the probe reaction. Steady-state analytical solutions for the concentration profiles of the reactant, the effectiveness factor of the pellets and the yields of the produced species are calculated. The shape, the size and the amount of zeolite in the composite particles are used as parameters. The comparison between theory and experiment shows satisfactory agreement.
