Abstract:
1. A method for producing a synthesis gas containing carbon monoxide and hydrogen from a source gas containing light hydrocarbons, comprising the steps of: performing low temperature steam reforming by adding steam to the source gas and converting the hydrocarbons of carbon numbers of 2 or higher in the source gas to methane, thereby obtaining a reformed gas containing said methane; premixing oxygen with said reformed gas; feeding a mixed gas of the oxygen and the reformed gas to a catalytic partial oxidation reactor; and performing a catalytic partial oxidation to react the oxygen with the methane in said reformed gas, wherein the low temperature steam reforming is performed is a pressure set to be from normal pressure to 8 Mpa, an inlet temperature of the low temperature steam reforming reactor is set to be from 300 to 400° C., an outlet temperature of the low temperature steam reforming reactor is set to be from 400 to 550° C., and an amount of the added steam is set to be from 0.1 to 3.0 mol with respect to 1 mol of carbon in the source gas.
