摘　　要：以甲醇为原料,采用阳离子交换树脂为催化剂,对甲醇脱水制二甲醚的工艺技术进行了研究。在固定床反应器中考察了压力、温度、空速等工艺条件对甲醇转化率的影响,取得了适宜的工艺参数:空速1.0h-1,压力1.6MPa(表),温度150～155℃,在此工艺条件下甲醇转化率达65%以上,二甲醚选择性为100%。The processes for producing dimethyl ether from methanol with cation exchange resin as catalyst was investigated. Effects of pressure , temperature and space velocity on conversion of methanol were studied in a laboratory fixed bed reactor. Optimal conditions for the reaction were obtained. The conversion of methanol could reach more than 65% and dimethyl ether selectivity reached 100% at conditions of space velocity 1. 0h^-1 ,pressure 1.6MPa and temperature 150 - 155℃.
