CATALYST FOR HYDROGEN TREATMENT OF HYDROCARBON OIL AND HYDROGEN TREATING METHOD OF GAS OIL

Japanese Patent JP3770679

B2

PROBLEM TO BE SOLVED: To produce a catalyst for a hydrogen treatment of a hydrocarbon oil having a high hydrogenation activity to an arom. compd. together with a high resistance to sulfur and also having a high desulfurizing performance and to provide a production method of a gas oil blend base material having low sulfur content and low arom. compd. content by executing a contact reaction of the gas oil containing the arom. compd. by using the catalyst. SOLUTION: In the catalyst, 0.1-8 mass % at least one kind platinum group metal based on the catalyst and expressed in terms of metal or 0.1-2 mass % germanium based on the catalyst and expressed in terms of metal is incorporated together with at least one kind platinum group metal as an active component for hydrogenation in the carrier containing 2-50 mass % silica, 2-20 mass % ziroconia and 30-96 mass % alumina. The gas oil is subjected to the hydrogen treatment by executing the contact reaction of a gas oil fraction containing the arom. compd. at 3-8MPa hydrogen partial pressure, at 200-370°C and at 0.3-5hr-1 liq. space velocity by using this catalyst.
