MOLDED SINTERED BODY, AND METHOD FOR PRODUCING MOLDED SINTERED BODY
The present invention relates to a molded sintered body containing a mayenite type compound, an inorganic binder sintered material, and a transition metal, wherein a content of the inorganic binder sintered material is 3 to 30 parts by mass with respect to 100 parts by mass of the molded sintered body, and in a pore size distribution of the molded sintered body obtained by pore size distribution measurement by a nitrogen adsorption method, the molded sintered body has at least one pore peak in each of a pore diameter range of 2.5 to 20 nm and a pore diameter range of 20 to 350 nm. The present invention also relates to a method for producing the molded sintered body, including a step of mixing a precursor of a mayenite type compound and a raw material of an inorganic binder sintered material to prepare a mixture; a step of molding the mixture to prepare a molded body of the mixture; a step of firing the molded body to prepare a fired product; and a step of supporting a transition metal on the fired product to produce a molded sintered body, wherein the step of preparing the mixture is a step of blending the raw material so as to satisfy the above-mentioned inorganic binder content, thereby providing a molded sintered body having high catalytic activity and high crushing strength, and a method for producing the molded sintered body.
