Contributions of three types of Ga sites in propane aromatization over Ga_2O_3/Ga-MOR catalysts

摘要

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_2O_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_2O_3 surface.
