Abstract

A situation where sulfur compounds originating from a castable are mixed into synthesis gas produced by way of a reforming reaction and the mixed sulfur compounds are separated and collected with carbon dioxide and further fed into a reformer to thereby degrade the reforming catalyst of the reformer by sulfur poisoning is avoided. Purge gas that is steam or steam-containing gas is made to flow into the piping to be used for a synthesis gas production apparatus and dried out to remove the sulfur compounds contained in the castable prior to the start-up of operation of the synthesis gas production apparatus, in order to prevent the sulfur compounds from being released by hot synthesis gas.

Abstract

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.

Abstract

[Problem] To provide a reformate production method and reformate production apparatus with which reformate can be obtained in high yields when producing reformate using supercritical water. [Solution] A reactor (1) is maintained at a temperature and pressure at or above the critical point of water, brings heavy oil and the supercritical water into contact, and while causing thermal cracking of said heavy oil to proceed, forms: a first phase from the heavy oil components obtained by thermal cracking of the heavy oil and supercritical water solubilized in said heavy oil components below; and a second phase from said supercritical water and light oil components extracted into said supercritical water above. A first mixed fluid is drawn out from said first phase from the lower part of said reaction unit so as to limit coke formation in said heavy oil components, while a second mixed fluid is drawn out from the second phase from the upper part of said reaction unit so as to limit gas formation from said light oil components. In a mixing unit (2), the heavy oil components of the first mixed fluid are mixed with the light oil components of the second mixed fluid to obtain the reformate.
