摘　　要：本文采用固定床反应装置对共沉淀法制备的二甲醚合成催化剂CuO-ZnO/HZSM-5制备条件进行考察,结果表明:CuO/ZnO=1(摩尔比)、沉淀温度在68～75℃之间、共沉淀时的pH值为9左右时,催化剂的活性最好.The performance of the catalysts prepared by precipitation of joint sedimentation was investigated by using fixed-bed reactor. Results showed that the condition of prepared catalyst was CuO/ZnO =1 （mol/mol）,temperature of sedimentation was between 68-75℃, pH of sedimentation was 9, activity of the catalyst was the best.
