Abstract
There is disclosed a method of manufacturing a synthesis gas comprising reacting hydrocarbons with water vapor in a reformer to produce a synthesis gas containing hydrogen, carbon monoxide and carbon dioxide, recovering carbon dioxide from combustion exhaust gas which has been discharged from the reformer by a carbon dioxide recovery apparatus provided with a carbon dioxide absorption tower and with a carbon dioxide-absorbing liquid regenerating tower, and feeding the carbon dioxide thus recovered, as a component of raw gas, to the upstream side and/or the downstream side of the reformer. The hot synthesis gas produced in the reformer is utilized as a heat source for regenerating a carbon dioxide-absorbing liquid in the carbon dioxide-absorbing liquid regenerating tower of the carbon dioxide recovery apparatus.
