摘要：

Pure propane was rarely used as an alkylating agent of benzene for the formation of cumene. However, by means of FTIR spectroscopy, Ga-modified MFI zeolite was shown to be a very active and selective catalyst for this reaction compared with H-MFI, H-Beta and Ga-modified Beta zeolites which lead to more coke formation.
