METHOD OF MANUFACTURING REGENERATED CATALYST FOR HYDROGENATION TREATMENT, AND METHOD OF MANUFACTURING PETROLEUM PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a regenerated hydrogenation treatment catalyst manufacturing method capable of manufacturing a regenerated catalyst for hydrogenation treatment which has a stable and high activity and gives a produced oil excellent in hue from a used hydrogenation treatment catalyst.

SOLUTION: A used hydrogenation treatment catalyst containing at least one of Group 6 metals and at least one of Groups 8 to 10 metals is subjected to regeneration treatment at a temperature of 250 to 380°C for 2 to 8 hours in air current at a flow rate of 20 to 200 NL/h*L-catalyst per unit volume of the catalyst to manufacture a regenerated catalyst for hydrogenation treatment.
