METHOD FOR MANUFACTURING REGENERABLE HYDROGEN TREATMENT CATALYST AND METHOD FOR PRODUCING PETROLEUM PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for easily manufacturing a regenerable hydrogenation treatment catalyst and a method for producing petroleum products by using the regenerable hydrogenation treatment catalyst.

SOLUTION: The hydrogenation treatment catalyst contains at least one kind selected from group 6 metals of the periodic table and at least one kind selected from group 8 metals to group 10 metals. When radial distribution curves each of which is obtained from the extended X-ray absorption fine structure area of a spectrum obtained by an extended X-ray absorption fine structure analysis of the unused hydrogenation treatment catalyst or the hydrogenation treatment catalyst after being used in hydrogenation treatment satisfy the condition: IM-O/I0M-O≤1.5 (wherein IM-Ois the intensity of a peak belonging to a group 6 metal atom-oxygen atom bond of the hydrogenation treatment catalyst after being used in the hydrogenation treatment; I0M-Ois that of the peak belonging to the group 6 metal atom-oxygen atom bond of the unused hydrogenation treatment catalyst), the hydrogenation treatment catalyst after being used in the hydrogenation treatment is decided to be regenerable. The hydrogenation treatment catalyst after being used in the hydrogenation treatment, which is decided to be regenerable, is regenerated.
