PROBLEM TO BE SOLVED: To provide a system for restraining the alkali poisoning of a catalyst for reforming tar, in which an alkali component in gasified gasses is adsorbed/removed suitably in a gasification process so that in the succeeding stage thereof the alkali poisoning of the catalyst for reforming tar can be restrained.SOLUTION: The system for restraining the alkali poisoning of the catalyst for reforming tar by removing the alkali component in the gasified gasses obtained by gasifying fuel includes; a fuel supply apparatus 10 for supplying fuel to a gasification furnace; a gasifying agent supply apparatus 30 for supplying a gasifying agent; a first supply apparatus 20 for supplying a mixture of a fluidizing medium with an alkali adsorbent to the gasification furnace 40 according to the supply of the fuel and the gasifying agent to the gasification furnace 40; the gasification furnace 40 for gasifying the fuel; and a catalytic tar reforming column 50 in which the catalyst for reforming the tar in the gasified gasses gasified in the gasification furnace 40 is packed. |
