摘要
The nature of diffusion phenomena in TiAlsilicalite and ZSM-5 catalysts has been investigated by means of the GC pulse method. Bulk, Knudsen, and intracrystalline contributions to the overall diffusion resistance have been evaluated by employing benzene as a probe molecule. The analysis of these results, together with those coming from a more general physicochemical characterisation of the solid, provide insight into the effect of pelleting pressure on the structure of the catalyst. There are shown to be considerable changes in catalytic activity and aging behaviour in propylene oligomerisation as a function of pelleting pressure. © 1990.
