Abstract
Influence of various zeolite catalyst factors such as, Si/Al ratio (35-132) , degree of H+ exchange (2-98%), calcination temperature (600 - 800 degrees C) and Ga-loading on time-on-stream activity/selectivity of Ga/H-ZSM-5 in the propane aromatization has been investigated. The time-on-stream activit y in the propane-to-aromatics conversion is found to be influenced strongly by the above zeolitic factors. The Ga/H-ZSM-5 zeolite catalysts undergo qu ite rapid deactivation due to coking.
