Dehydrogenation and aromatization of propane over rhenium-modified HZSM-5 catalyst

Re/HZSM-5 showed higher activity toward dehydrogenation and aromatization compared with HZSM-5 and Ga/HZSM-5 catalyst. Carbon dioxide largely inhibited the propane transformation, while methane improved the selectivity of aromatic products and inhibited the decomposition of propane.
