Abstract

The aromatization of methane over a Mo/HZSM-5 catalyst was carried out in the presence of oxygen. It is shown that the addition of a small amount of oxygen is beneficial to improve the durability of the catalyst. UV-Raman spectra disclose that the carbonaceous deposits formed on the HZSM-5 are mainly polyolefinic and aromatic, while that on the Mo/HZSM-5 is mainly polyaromatic. The small amount of O-2 added may partly remove the coke deposits onthe active sites and keep the catalyst as MoOxCy/HZSM-5, thus resulting inan improvement of the catalytic performance of the Mo/HZSM-5 catalyst.
