Abstract:
1. A process for producing synthesis gas for the Fischer-Tropsch synthesis comprising: an adsorbing step of adsorbing impurities contained in natural gas by active carbon to remove the impurities therefrom; a hydro-desulfurizing step of hydrogenating sulfur content in the natural gas in the presence of a hydrogenation catalyst under a partial pressure of hydrogen of 100 to 200 kPa and desulfurizing the sulfur content by an adsorbing agent; a hydrogen supplying step of supplying the natural gas after the hydro-desulfurizing step with hydrogen (H a reaction step of reacting the natural gas, carbon dioxide, and steam in the presence of a catalyst for reforming to obtain synthesis gas for the Fischer-Tropsch synthesis; and a cooling step of cooling the synthesis gas for the Fischer-Tropsch synthesis at a cooling rate of 2000-4000° C./second.
