Studies of Catalysts for Methane Aromatization——The Reaction Performance and Surface Property of Mo-M/HZSM-5 Catalysts Under Oxygen-free Conditions
Abstract:
The promotion effects of Zn,W,Cu,Cr and Ni additives on the methane aromatization performances of Mo/HZSM-5 catalyst have been investigated. Much higher conversion and selectivity for methane were observed on modified Mo-M/HZSM-5. The methods of isopropanol decomposition, NH3-TPD-MS and thermal analysis were used for characterization of the catalysts. The results appeared to be related with the methane aromatization performance that catalyst which gave high aromatics yield and good stability had fewer carbon deposit and considerable acid amount, as well as certain strong acid amount and relative strong dehydrogenating sites.
