Ammonia synthesis catalyst structure, method for producing the same, ammonia synthesis apparatus, and method for synthesizing ammonia

摘要

Provided are an ammonia synthesizing catalyst structure capable of suppressing a decrease in catalytic activity and achieving a long life, a method for producing the same, an ammonia synthesizing apparatus, and a method for synthesizing ammonia. The ammonia synthesis catalyst structure (1) comprises a carrier (10) having a porous structure composed of a zeolite-type compound and at least one metal contained in the carrier (10), and has an average particle size of 0.7 nm to 5 nm. And a carrier (10) having an average inner diameter of 0.50 nm to 0.64 nm communicating with each other, the ammonia synthesizing catalyst substance being the carrier (10). ) Present in at least said passage (11).
