COMPLEX METHOD FOR PRODUCING FUEL DIMETHYL ETHER AND GASOLINE FROM HYDROCARBON GASES Russian patent published in 2005 - IPC

Abstract RU 2266893 C2

FIELD: petroleum chemistry, chemical technology.

SUBSTANCE: method involves successive carrying out stages for producing gas-synthesis, synthesis of dimethyl ether and synthesis of gasoline from gas-phase flow containing dimethyl ether and fractionation of products in gasoline synthesis. Gas-synthesis is prepared by method of high-rapid nonequilibrium partial oxidation with formation in outlet of the corresponding stage of the complex process the mole value ratio H₂/CO in fresh gas-synthesis in the range 1.35-1.65 that is not typical for equimethanol technology. Invention provides schemes and parameters in fractionation of vapor-gaseous mixture in outlet from reactor compartment in synthesis of dimethyl ether and combinations of schemes with recycle of unreacted and flowing gases are taken for the complex scheme.

EFFECT: improved producing method.
