Abstract

The influence of water in the CH₄ feed on the performance of 3%Mo/ZSM-5 catalyst during methane direct aromatization under supersonic jet expansion (SJE) condition was investigated. We observed that both surface Mo₂O_xC_y and β-Mo₂C species are catalytically active for methane aromatization under SJE condition. The presence of water can promote the removal of surface carbon before the generation of aromatic-type and/or graphitic carbon. In appropriate amount, water can improve the stability of surface Mo₂O_xC_y, and hence resulting in better catalytic performance. The study provided valuable information relevant to the direct utilization of methane hydrate.
