中文摘要：

采用等体积浸渍法制备了不同负载量（1％～7％）的CuO／HZSM-5催化剂，在固定床反应器中研究了不同反应温度、溴甲烷流量以及CuO负载量对溴甲烷芳构化催化性能的影响。采用SEM、XRD、N，吸附脱附、TEM、XPS、TG、DSC、NH3-TPD等技术对反应前后的催化剂进行表征。XRD结果显示活性组分CuO在HZSM．5上具有很好的分散性，并且反应后Cu晶型不变。NH3-TPD结果显示3％的CuO负载后，催化剂强酸量增加。在CuO负载量为3％，温度为360℃，反应空速为240ml·g^-1．h^-1条件下得到最高的芳烃收率（22．3％）。XPS结果显示反应后在催化剂上主要的积炭为石墨碳。催化剂稳定性测试结果表明反应40h内催化活性没有明显下降。

英文摘要：

CuO/HZSM-5 catalysts with 1%-7% CuO loading, which were prepared by incipient wetness impregnation, were used to study catalytic performance in the conversion of CH3Br to aromatic compounds in a fixed-bed reactor by changing temperature, CH3Br flow rate and CuO loading. Fresh and used catalysts were characterized by SEM, TEM, XRD, XPS, TG, DSC, N2 adsorption and desorption, and NH3-TPD. XRD results showed that CuO was highly dispersed on HZSM-5 and structure of CuO crystals did not change during reaction. NH3-TPD results showed that 3% （mass） CuO loading increased strong acidity of catalyst. XPS results showed that coke deposition on used CuO/HZSM-5 catalyst was mainly graphite. The highest aromatic yield of 22.3% was achieved at condition of 3% （mass） CuO loading, 360℃ temperature and 240 ml.g^-1.h^-1 GHSV. The 3% （mass） CuO/HZSM-5 maintained stable catalytic activity within 40 h reaction time.
