摘　　要：利用雷尼铜在低温氧化后制备多孔CuO催化剂,采用XRD,XPS,SEM,H2-TPR,HRTEM等对催化剂的组成和形貌进行表征,并在微反应装置上评价了催化剂在气相乙烯脱CO反应中的性能。实验结果表明,多孔CuO催化剂具有良好的CO脱除能力,活性主要来源于催化剂中纳米级的CuO粒子及Cu2O粒子中的Cu^+的共同作用;在反应压力为2.0 MPa、反应温度为90℃、气态空速在3 000 h^-1的条件下,多孔CuO催化剂可以将乙烯中CO脱除至3×10^-8(w)以下。Multiporous CuO catalyst was prepared by oxidation reaction of Raney Cu at low temperature.The composition and structure of the multiporous CuO catalysts were characterized by XRD,XPS,SEM,H2-TPR and HRTEM,and the performance of the catalyst for removal of CO from gas ethylene was evaluated in microreactor.Results show that the performance of multiporous CuO catalyst,which is active because of the effects of CuO particles and the Cu+in Cu2O particles,in CO removal is good.Under the reaction conditions of 90℃,2.0 MPa,3 000 h^-1,multiparous CuO catalyst can reudce the CO content in the ethylene to lower than 3×10^-8(w).
