Structured catalyst for catalytic cracking or hydrodesulfurization, catalytic cracking apparatus and hydrodesulfurization apparatus including the structured catalyst, and method for producing structured catalyst for catalytic cracking or hydrodesulfurization

A structured catalyst for catalytic cracking or hydrodesulfurization comprising:

• a support of a porous structure comprising a zeolite compound having a framework;
• and
• at least one type of metal oxide nanoparticles present in the support, wherein
• the support has a plurality of channels connecting with each other,
• the metal oxide nanoparticles are present at least in the channels of the support, and
• the metal oxide nanoparticles are composed of a material containing any one or two or more of the oxides of Fe, Al, Zn, Zr, Cu, Co, Ni, Ce, Nb, Ti, Mo, V, Cr, Pd, and Ru,
• wherein the channels have any one of a one-dimensional pore, a two-dimensional pore, and a three-dimensional pore defined by the framework of the zeolite compound and an enlarged pore portion that has an inner diameter greater than that of any of the one-dimensional pore, the two-dimensional pore, and the three-dimensional pore, is not defined by the framework of the zeolite-type compound, and is greater than or equal to an average particle size of the metal oxide nanoparticles,
• wherein the metal oxide nanoparticles are present at least in the enlarged pore portion to prevent contact between the metal oxide nanoparticles in the enlarged pore portions, and the average particle size of the metal oxide nanoparticles is greater than any one of the one-dimensional pore, the two-dimensional pore, and the three-dimensional pore defined by the framework of the zeolite-type compound, and
• wherein a skeletal structure of the zeolite compound is selected from a FAU type, a MTW type, a MFI type, a FER type, a LTA type, a MWW type, a MOR type, a LTL type, and a BEA type.
