Abstract. At present, obtaining dimethyl ether from syngas in one step is an actual issue, and the effect of various factors on the process of direct synthesis of dimethyl ether from syngas in one step was studied in Cu2O·ZnO·ZrO2/YuKTs catalyst. As a result of studies conducted on the effect of various factors on the yield of target products in the process of obtaining dimethyl ether from synthesis gas, it was found that the increase of pressure, temperature, mole ratio of hydrogen to hot gas, and the mole ratio of hydrogen:hot gas leads to an increase in conversion of hot gas. An increase in the volume velocity reduces the conversion of the is gas, because the reaction between the reactants in the gas phase and the methanol catalyst surface does not have time to occur due to the low contact time. It has been proven that the increase in the ratio of gas to hydrogen moles leads to an increase in the yield of dimethyl ether and the conversion of gas. As a result of the research, the following optimal conditions for obtaining dimethyl ether from hydrogen gas in one step were determined: R=1 MPa, T=300℃, hydrogen:gas gas=2, volumetric speed 1000 hour-1. In this case, the conversion of exhaust gas does not decrease for 220 hours. At the same time, the physicochemical and textural characteristics of the Cu2O·ZnO·ZrO2/YuKTs catalyst were studied.

Keywords: natural gas, synthesis gas, conversion, dimethyl ether, catalyst, synthesis, kinetic law. Purpose of work - consists in studying the kinetic laws of the synthesis reaction of dimethyl ether in one step from syngas and the textural characteristics of the catalyst.
