Hydrofining catalyst

The invention relates to a hydrofining catalyst which is obtained by adding a carrier into a dipping liquid for aging and drying after dipping, and then activating. The catalyst, containing the carrier, molybdenum and cobalt, is characterized by containing molybdenum oxide 5-25%, cobalt oxide 1-6%,...

Beschreibung
Zusammenfassung:	The invention relates to a hydrofining catalyst which is obtained by adding a carrier into a dipping liquid for aging and drying after dipping, and then activating. The catalyst, containing the carrier, molybdenum and cobalt, is characterized by containing molybdenum oxide 5-25%, cobalt oxide 1-6%, tungstic oxide 0-15%, nickel oxide 0-4%, and alkali metal oxides 0-4.5%, by the catalyst weight of 100%. Besides, the catalyst pore volume is 0.30-0.85ml/g, and the specific surface area is 110-380 m /g. Compound solvent in the catalyst preparation contains ammonia water and polyamine complexingagent at the same time. The catalyst of the invention while undergoing hydrodesulfurization, saturates monoolefine to the maximum through hydrogenation, to be able to meet the requirements of an oil product with changeable sulfur and diene contents and high air speed running. Catalyst has good hydrogenation activity, high selectivity, long running time and superior anti coking performance.
