Abstract

See full text

It is avoided that the sulfur compounds originating from the castable is mixed into produced synthesis gas, the mixed sulfur compounds are separated and collected with carbon dioxide, the collected carbon dioxide is recycled as raw material gas and then the sulfur compounds is directly supplied to the reformer to consequently degrade the reforming catalyst in the reformer by sulfur poisoning. The carbon dioxide separated and collected in the carbon dioxide removal step is introduced into the desulfurization apparatus of the desulfurization step or the sulfur compounds adsorption apparatus before being recycled to the reformer to remove the sulfur compounds.
