HYDROGENATION CATALYST AND MANUFACTURING METHOD THEREOF AND HYDROGENATING METHOD OF HYDROCARBON OIL

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a hydrogenation catalyst having improved desulfurization activity, denitrogen activity and de-aromatic activity. SOLUTION: The hydrogenation catalyst is manufactured by one of the following processes. (1) A water soluble organic compound having >=150 deg.C boiling point or decomposition temperature is previously carried on a refractory inorganic oxide carrier and next, a compound of group IV metals in periodic table is carried and further a compound of group VI metals and a compound of group VIII-X metals are carried. (2) A water soluble organic compound having >=150 deg.C boiling point or decomposition temperature and a compound of group IV metals in periodic table are carried on a refractory inorganic oxide carrier and further a compound of group VI metals and a compound of group VIII-X metals are carried. (3) A water soluble organic compound having >=150 deg.C boiling point or decomposition temperature, a compound of group VI metals and a compound of group VIII-X metals are carried on a refractory inorganic oxide carrier and next, a compound of group IV metals in period table are carried.
