1. A structured catalyst for hydrodesulfurization, comprising:
a support of a porous structure composed of a zeolite-type compound; and
at least one catalytic substance present in the support,
the support comprising channels connecting with each other, and
the catalytic substance being present at least in the channels of the support,
wherein the channels have any one of a one-dimensional pore, a two-dimensional pore, and a three-dimensional pore defined by a framework of the zeolite-type compound and an enlarged pore portion which has a diameter greater than that of any of the one-dimensional pore, the two-dimensional pore, and the three-dimensional pore, wherein the enlarged pore portion is formed from a disruption of a skeletal structure of regular mesopore material of the channels, the enlarged pore portion is formed from the regular mesopore material, and an inner diameter of the enlarged pore portion is greater than or equal to a diameter of the catalytic substance,
the catalytic substance is present at least in the enlarged pore portion, and a particle size of the catalytic substance is greater than an inner diameter of 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,
the catalytic substance is made of metal oxide nanoparticles, wherein the zeolite-type compound is selected from FAU type (Y type or X type), MTW type, MEI type (ZSM-5), FER type (ferrierite), LTA type (A type), MWW type (MCM-22), MOR type (mordenite), LTL type (L type), and BEA type (beta type).
