英文摘要: The dehydro-aromatization of methane over a Mo-modified penta-sil type high-silica zeolite containing phosphoric and rare earth oxide (abbreviated as Mo/HZRP-1) was investigated. As a modification of HZSM-5, HZRP-1 is also a good support for the preparation of Mo-based zeolite catalysts, and is active for methane dehydro-aromatization. Mo/HZRP-1 catalysts are more active at high Mo loadings compared with Mo/HZSM-5 catalysts. Al-27 MAS NMR spectra of Mo/HZRP-1 reveal that there are two kinds of framework Al in HZRP-1. It is suggested that only the tetrahedral coordinated Al atoms in the form of Al-O-Si species in the zeolite, in the proton forms, are responsible for the formation of aromatics.
