Co-Aromatization of isobutane and propane over H-ZSM-5 and Zn/ZSM-5 catalysts prepared by differentcrystallization time ranging from 24 h to 96 h at 180 8C was studied. The samples were characterized viaXRD, BET, SEM and NH3-TPD. A maximum for crystallinity was observed at 72 h with 98% and Acidityalong with crystal size increased with time. Performance tests in a fixed bed reactor at 550 8C showedthat catalytic activity increased with crystallization time while the aromatics selectivity increased withcrystallinity. The results also indicated that conversion of propane in the presence of isobutane wasdramatically lower than individual propane test.
