    • PROBLEM TO BE SOLVED: To obtain a catalyst reactor which prevent an excessive increase of the pressure loss even when a fine-mesh filter capturing a catalyst in powder form is mounted.
      SOLUTION: The catalyst reactor has a passage structure 7 comprising a reaction gas generation passage 5 containing a catalyst 13 in order to generate a reaction gas 4 from an incoming raw material 3, a reaction gas passage 6 arranged in the reaction gas generation passage 5 through an intermediate wall 9 and allowing the reaction gas 4 to pass through in the direction opposite to that for the raw material 3, and a connection passage 19 connecting the reaction gas generation passage 5 with the reaction gas passage 6. The passage 19 has a hole 5a formed in the intermediate wall 9 and connecting the passages 5 and 6, and a reaction gas blocking section 11 blocking the flow of the reaction gas 4 within the passage 19 is formed in the intermediate wall 9 on the side opposite to the side of the catalyst 13 with respect to the hole 5a. The area of the hole 5a is larger than the cross-section of the reaction gas generation passage 5 or reaction gas passage 6 in the direction perpendicular to that for the flow of the reaction gas 4, and a filter 15 allowing the reaction gas 4 to pass through is arranged in the hole 5a.
