Gallosilicate MFI catalysts were prepared via the addition of MPS (3-mercaptopropyl-trimethoxysilane). Acid site distributions of the gallosilicate MFI catalysts were analyzed. The gallosilicate MFI catalysts made via the MPS addition show enhanced Lewis acidity. Addition of MPS improves both propane conversion rate and propylene selectivity.
