摘　　要：本文采用共沉淀沉积法制备了一步法合成二甲醚的双功能催化剂,并在固定床高压流动反应装置上对其催化性能进行研究,考察了MnO2 助剂对Cu -ZnO -ZrO2 /HZSM - 5催化剂性能的影响以及工艺条件对二甲醚合成的影响。采用TPR、XRD等测试方法对催化剂进行了表征,结果证明:MnO2 助剂的加入,能够增加活性中心数量,提高催化剂的活性。The double function catalysts of one-step synthesizing of dimethyl ether were produced by using precipitation of joint sedimentation and the catalysts performance was studied with a fixed-bed flow apparatus.The influence of MnO_2 for CuO-ZnO-ZrO_2/HZSM-5 and technologic conditions were investigated.The catalysts were determined by means of TPR, XPD,the results of tests indicated that MnO_2 may make the catalyst activity increasing.
