摘要：

A new Fe-0/ZSM-5 catalyst was investigated for tar decomposition under microwave irradiation using a model compound (methylbenzene). Systematic thermal imaging, temperature-programmed oxidation, and X-ray photoelectron spectroscopy were used to investigate the decomposition mechanism and the product composition. The microwave cracking of the tar model was efficiently catalyzed by Fe-0/ZSM-5 with micro-tip discharging. While the methylbenzene concentration decreased slightly when microwaved over H-ZSM-5, it was significantly reduced, by 50%, when irradiated over Fe-0/ZSM-5. These results suggest that micro-tip discharging, which was possibly induced by microwave radiation, is primarily responsible for the catalytic cracking of methylbenzene in this system. These results will benefit future investigations related to thermal cracking.
