摘　　要：在实验室进行了对采用浆态一步法合成二甲醚研究 ,系统考察了各种工艺条件 ,如温度、压力、空速、氢碳比等参数对反应的影响 ,获得了最佳的操作条件 :温度 2 5 0℃～ 2 70℃ ,压力 4～ 5MPa ,空速 30 0 0～ 6 0 0 0ml/g .cat/h ,氢碳比 1∶1,在此基础上进行了 30 0 0t/a的中试实验 ,取得了满意的结果。DME synthesis in slurry reactor by one step process is studied in laboratory under various process conditions, such as temperature, pressure, space velocity, H/C ratio et al., on the reaction. The optimum operation conditions are obtained that the temperature is 250℃-270℃,the pressure is 4-5MPa, and the space velocity is 3000-6000ml/g.cat/h,the.H/C ratio is 1:1.Based on that 3000t/a pilot test is carried out and good resulus are achieved.
