Synthesis gas production catalyst structure and precursor thereof, synthesis gas production apparatus, and method of producing synthesis gas production catalyst structure

Abstract

A synthesis gas production catalyst structure or the like which can maintain stable high catalytic activity for a long period of time without degradation and can allow efficient production of a synthesis gas including carbon monoxide and hydrogen. The synthesis gas production catalyst structurefor use in producing a synthesis gas comprising carbon monoxide and hydrogen, the synthesis gas production catalyst structureincluding: supports each having a porous structure and including a zeolite-type compound; and at least one catalytic material present in the support, in which each of the supports has channels communicating with one another, each of the supports has a ratio (L/d ratio) of long side dimension L to thickness dimension d of 5.0 or more, and the catalytic material is present at least in the channel of each of the supports.
