摘要

The product formation pathways of alkylation of benzene with propane on HZSM-5 and Ga-modified HZSM-5 suggest that acid-catalyzed cracking of propane predominates on HZSM-5, leading to the formation of toluene and ethylbenzene. Over Ga-modified HZSM-5, a bifunctional pathway is noted and cracking of propane and propane dehydrogenation are controlled by Lewis (Gax+)/Brönsted (H+) acid sites ratio.
