Catalyst structure and method for producing same, and method for producing hydrocarbon by use of catalyst structure

A catalyst structure comprising:

• a support that has a porous structure and comprises a zeolite-type compound;
• and
• a functional material present in the support,
• the functional material comprising:
• a first metal element selected from the group consisting of cobalt (Co), nickel (Ni), iron (Fe), and ruthenium (Ru);
• and
• a second metal element selected from the group consisting of metal elements belonging to Groups 1, 2, 4, 7, and 12 of periodic table, wherein
• the support has channels communicating with one another,
• the functional material is present at least in the channels of the support,
• the channels have any one of a one-dimensional pore a two-dimensional pore, a three-dimensional pore of a framework structure of the zeolite-type compound, and an enlarged pore portion which is not defined by the framework structure of the zeolite-type compound and has a diameter greater than any one of the one-dimensional pore, the two-dimensional pore and the three-dimensional pore,
• the enlarged pore portion has a greater diameter than the functional material,
• the functional material has a diameter greater than any one of the one-dimensional pore, the two-dimensional pore and the three-dimensional pore,
• the functional material includes metal oxide nanoparticles, and
• the framework structure of the zeolite-type compound is selected from the group consisting of FAU type, MTW type, MFI type, FER type, LTA type, MWW type, MOR type, LTL type, and BEA type.
