Benzene alkylation with propane over metal modified HZSM-5

Propane alkylation with benzene over modified zeolite catalysts is one of the good ways for propane utilization. The catalytic performance over various metal modified HZSM-5 catalysts was studied. Addition of Pt or Zn resulted in remarkable increase of the activity. Addition of Mo depressed the activity, but greatly improved selectivity to aromatics, with the content of products from direct addition of propyl group to benzene (IPB and NPB) in the products reaching 81.5 mol%.
