摘　　要：采用乙酸回流MoO3的方法制备了MoAC,以其为钼源分别制备了Mo/HMCM-22,Mo/HMCM-49和Mo/HZSM-5催化剂,并考察了各催化剂在甲烷无氧芳构化反应中的催化性能.结果表明,以MWW型分子筛(HMCM-22和HMCM-49)为载体时,催化剂的芳烃收率和催化剂稳定性均比传统浸渍法制备的催化剂明显提高;而以HZSM-5为载体时,催化剂的甲烷无氧芳构化活性无明显变化.The direct conversion of methane has been a research topic in heterogeneous catalysis for the last few decades. It was reported in 1993 that methane undergoes dehydrogenation and aromatization over a Mo/ HZSM-5 catalyst at 973 K under nonoxidative condition. Since then, the reaction of methane dehydroaromatization （MDA） has attracted much attention in the field of heterogeneous catalysis.
