Abstract
A method of manufacturing a synthesis gas, which makes use of a synthesis plant comprising a reformer having a steam reforming reaction tube, a combustion radiation portion provided around the reaction tube, for heating the reaction tube, and a convection portion communicating the combustion radiation portion. A steam-containing natural gas is prepared by adding stream to a natural gas. The steam-containing natural gas is preheated by passing the natural gas through a convection portion of reformer, the natural gas preheated being subsequently fed to the reaction tube. After being preheated in the convection portion, carbon dioxide is fed to the reaction tube, thereby producing a synthesis gas containing hydrogen and carbon monoxide.
