摘要：
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 degrees 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 degrees C). The propane aromatization activity and selectivity increases sharply with the increase in the strong acid sites of the Ga/H-ZSM-5. (C) 2000 Elsevier Science B.V. All rights reserved.
