A process for producing an activated catalyst for a Fischer-Tropsch synthesis reaction that includes a step of subjecting a Fischer-Tropsch synthesis reaction catalyst prepared by loading an active metal on an inorganic support to a reduction treatment by a gas containing hydrogen gas. This reduction treatment is performed in any reactor among a reactor (10) that conducts a hydrodesulfurization of a hydrocarbon feedstock used for producing the synthesis gas that functions as the feedstock for the Fischer-Tropsch synthesis reaction, a reactor (30) that conducts the Fischer-Tropsch synthesis reaction, and reactors (50, 52, 54) that conduct hydroprocessing of a synthetic oil that has been synthesized by the Fischer-Tropsch synthesis reaction.

There is provided a method for recovering hydrocarbon compounds from gaseous by-products generated in a Fischer-Tropsch synthesis reaction. The method includes absorbing light hydrocarbon compounds and a carbon dioxide gas from the gaseous by-products using an absorption solvent including liquid hydrocarbon compounds and a carbon dioxide gas absorbent, separating the absorption solvent which has absorbed the light hydrocarbon compounds and the carbon dioxide gas into the liquid hydrocarbon compounds and the carbon dioxide gas absorbent, heating the separated liquid hydrocarbon compounds to recover the light hydrocarbon compounds from the separated liquid hydrocarbon compounds, heating the separated carbon dioxide gas absorbent to strip the carbon dioxide gas from the separated carbon dioxide gas absorbent, and reusing the gaseous by-products from which the light hydrocarbon compounds and the carbon dioxide gas are absorbed as a feedstock gas for the Fischer-Tropsch synthesis reaction.

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.

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.
