Abstract:
A method of manufacturing a synthesis gas containing CO and H2, which is suited for use in synthesizing gasoline, kerosene and gas oil by way of the Fisher-Tropsch reaction system; the method comprising the steps of;feeding a steam-mixed natural gas to a reformer which is provided with a combustion radiation portion for burning a fuel, the reformer being designed to be heated by the combustion radiation portion; recovering carbon dioxide from a combustion exhaust gas generated at the combustion radiation portion; and adding the carbon dioxide to the steam-mixed natural gas at a location on an upstream side of the reformer, thereby allowing a reforming reaction to take place to obtain a synthesis gas comprising CO and H2 at a molar ratio of H2/CO=1 to 2.5, which is suited for use in synthesizing gasoline, kerosene and gas oil.
