METHOD FOR PREPARING SYNTHESIS GAS, METHOD FOR PREPARING DIMETHYL ETHER USING SYNTHESIS GAS, AND FURNACE FOR PREPARING SYNTHESIS GAS

WIPO Patent Application WO2004078645

A8

A method for producing a synthetic gas involving subjecting a hydrocarbon to a partial combustion by means of a synthetic gas generating furnace having a catalyst layer therein to generate a gas, and modifying the gas by the aid of a catalyst, to produce a synthetic gas containing hydrogen and carbon monoxide as main components, characterized in that the temperature at the outlet of the catalyst layer is controlled to 1100 to 1300°C, and the resultant synthetic gas has a concentration of carbon dioxide of 10 % or less. The method can be employed for producing a synthetic gas which contains no hydrocarbon and is reduced in the concentration of carbon dioxide.
