A method of producing motor fuels

 

Usage: to produce motor fuels. Essence: spend synthesis-gas non-catalytic gas-phase oxidative conversion of natural gas with oxygen at a temperature of 800-1500C and a pressure of 1-10 MPa. This is followed by catalytic conversion of synthesis gas in the synthesis reactor, dimethyl ether, followed by cooling the product gas mixture, and the division into liquid and gas phase. Thus from the liquid phase produce dimethyl ether, which is sent to the catalytic reactor synthesis gas, and a gas phase containing neprevyshenie components of synthesis gas, is directed to re-catalytic conversion in an additional reactor for the synthesis of dimethyl ether without mixing with the original synthesis gas. The technical result is an increase in the yield of dimethyl ether and accordingly gasoline fraction and reduce costs through the use of oxygen. 2 C.p. f-crystals, 1 Il.
