The aromatization of n hexane and mixed C 4 hydrocarbon was investigated under microwave heating over ZnNi/HZSM 5 catalyst of lower activity in order to compare with that under the conventional heating. For the n hexane aromatization, the selectivity for benzene and toluene by the microwave heating at 450 ℃ increases by 4% and 5%, respectively, and the aromatics yield by the microwave heating at 480℃ increases by 4% , compared with those by the conventional heating. For the mixed C 4 olefine aromatization, the BTX yield by the microwave heating at 400 ℃ increases by 17 08% and the aromatics selectivity is also higher than that by the conventional heating.
