HYDROGENATION DESULFURIZATION CATALYST FOR PETROLEUM HYDROCARBON AND METHOD OF HYDROGENATION DESULFURIZATION USING THE SAME

摘要

A hydrogenation desulfurization catalyst that can attain a strikingly high desulfurization depth of 10 ppm by mass or below sulfur content, exhibiting high denitrogenation activity and that has high nitrogen resisting capability to nitrogen compounds being desulfurization reaction inhibiting substances. There is provided a hydrogenation desulfurization catalyst for petroleum hydrocarbons characterized in that an inorganic porous support composed mainly of alumina contains, as active metals, at least one metal selected from among the metals of Group 8 of the periodic table and at least one metal selected from among the metals of Group 6A of the periodic table in a molar ratio of [oxide of metal of Group 8]/[oxide of metal of Group 6A] ranging from 0.105 to 0.265, the content of metals of Group 6A in terms of oxide being in the range of 20 to 30 mass% based on the weight of catalyst.
