HYDRODESULFURIZATION CATALYST FOR HYDROCARBON OIL

摘要

PROBLEM TO BE SOLVED: To provide a hydrodesulfurization catalyst having higher performance than conventional ones.SOLUTION: A hydrodesulfurization catalyst for hydrocarbon oil includes a support having a ratio of the diffraction peak area indicating the crystal structure of boehmite (020) plane measured in X-ray diffraction analysis to the diffraction peak area indicating the crystal structure of aluminum attributed to γ-alumina (440) plane of 1/10 or more, and at least one metal component selected from the group VIA and the group VIII in the periodic table, which is supported on the support. The molar ratio of the metal component selected from the group VIII to the metal component selected from the group VIA is 0.13 to 0.22.
