【摘要】 本文以TPSR为主要实验手段,结合X—衍射图谱分析,孔隙结构分析,TPR及TPD的实验结果,对以Cu/ZnO/Al₂O₃为催化剂的低变反应体系进行了研究。结果表明:在CO变换为CO₂的过程中,有一甲酸型中间络合物生成。这一中间络合物是由吸附在Cu/ZnO/Al₂O₃上的CO和H₂O（g）相互结合而生成的,其生成部位由催化剂组元ZnAl₂O₄所提供,且其生成后在催化剂表面上发生了转移,尔后分解,分解产物脱附形成了CO₂和H₂。更多还原

【Abstract】 The low temperature carbon monoxide conversion reaction on the CuO/ZnO/Al₂O₃ catalyst was studied by TPSR,combined with the X-diffraction, pore structure analysis, TPR and TPD. The results show that an intermediate complex compound of HCOOH is formed by a combination of CO and H₂O（g） which are adsorbed on CuO/ZnO/Al₂O₃ catalyst. And the active site for forming HCOOH is provided by the eatalyst component ZnAl₂O₄·After HCOOH is formed, it shifts and then decomposes. CO₂ and H₂ are formed by the desorption of the decomposition products.更多还原
