【Abstract】 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.更多还原
