Contributions of three types of Ga sites in propane aromatization over Ga203/Ga-M0R catalysts

Contributions of three types of Ga sites to propane conversion into aromatics were examined by using model catalysts, i.e., gallosilicate of MOR structure with deposited Ga 2 O 3 particles. The rates of propane conversion and aromatics formation were correlated with the densities of three types of Ga sites determined by NH 3 -TPD, and it was shown that the propane conversion and the aromatics formation were limited by Ga sites on Ga 2 O 3 surface.
