- W137082331 abstract "The reaction of propane and propene over HZSM-5, Ga HZSM-5, PtHZSM-5, PtCu HZSM-5 and PtGa HZSM-5 catalysts have been comparatively investigated. From the data obtained it is shown that the conversion of propane is favoured over Pt and Ga based zeolites, Ga HZSM-5 showing the highest selectivity towards aromatics. The aromatic formation proceeds through propene, oligomers, dienes, trienes intermediates over Ga based catalysts, while on Pt based catalyst the main path is probably through the formation of cycloalkanes following the dehydrogenation into aromatics. Furthermore Pt favours the hydrogenolysis reactions thus lowering the selectivity to aromatics. Alloying Pt with Cu or with Ga suppress the hydrogenolysis reaction with subsequent increase of the aromatic selectivity." @default.
