Abstract
The influence of zeolite factors, such as Ga loading (0-3%), Si/Al ratio (35-132), degree of H+ exchange (2-98%) and calcination temperature (600-800°C), affecting zeolitic acidity on the activity and selectivity of Ga/H-ZSM-5 in the aromatization of propane has been investigated. The activity and selectivity in propane-to-aromatics conversion are found to be influenced strongly by the above zeolite factors. The aromatization activity and selectivity of the zeolite shows a close relationship with its strong acidity (measured in terms of pyridine chemisorbed at 400°C). The propane aromatization activity and selectivity increases sharply with the increase in the strong acid sites of the Ga/H-ZSM-5.
