Catalyst structure for synthesis gas production, synthesis gas production device, and method for producing catalyst structure for synthesis gas production

A method of producing a catalyst structure for synthesis gas production, the method comprising:

• a first firing step that comprises firing a precursor material (B) comprising an iron-group element-containing solution and a precursor material (A) for obtaining a carrier having a porous structure and comprising a zeolite-type compound, the precursor material (A) having pores with a size of 13.0 nm or less and being impregnated with the iron-group element-containing solution;
• a hydrothermal treatment step that comprises hydrothermally treating a precursor material (C) obtained by firing the precursor material (B);
• a step that comprises impregnating, with a specific transition metal element-containing solution, a precursor material (D) obtained by hydrothermally treating the precursor material (C);
• and
• a second firing step that comprises firing the precursor material (D) impregnated with the specific transition metal element-containing solution,
• wherein the iron-group element is at least one selected from the group consisting of nickel, iron, and cobalt, and
• the specific transition metal element is selected from transition metal elements with Redox capacity.
