Obtaining dimethyl ether from synthesis gas with the use of a two-layer catalyst was studied. An optimum level-by-level loading was determined for two catalytic systems such as methanol production catalyst Katalco-58 and methanol dehydration catalyst γ-Al₂O₃ It was demonstrated that increasing the temperature and contact time results in increasing the CO conversion level and the yield of dimethyl ether, whereas their maximum values are attained at a pressure of 3 MPa. The optimum process conditions are: Т = 280 °С, Р = 3 MPa, Н₂/СО = 2, the contact time 6 s.
