Where and how shape selectivity of molecular sievers operates in refining and petrochemistry catalytic processes

摘要

Zeolites play an important role in many catalytic processes of modern refining and petrochemistry. Their shape selectivity is always a key factor and here we look at the ways it operates in the principal processes either industrilized or with a good industrial potential: cracking, hydrocracking, isomerization of short or long paraffins and of butene, aromatic transformations by isomerization, disproportionation/transalkylation, and alkylations.
