Abstract: A grading system and an application of a hydrogenation catalyst and a grading method of the hydrogenation catalyst are provided. The system contains M hydrogenation catalysts sequentially filled in a material flow direction. An R value of an Nth hydrogenation catalyst is not less than an R value of an (N−1)th hydrogenation catalyst, and the R value of at least one Nth hydrogenation catalyst is greater than the R value of the (N−1)th hydrogenation catalyst. N is an integer greater than 2 and not greater than M; the R value is a ratio of molar content of the VIII group metal element in the hydrogenation catalyst characterized by an X-ray photoelectron spectrum to weight content of the VIII group metal element in terms of oxides in the hydrogenation catalyst characterized by an X-ray fluorescence spectrum. The hydrogenation catalysts having different surface nickel atom concentrations are used for grading, thereby improving denitrification and the hydrogenation saturation performance of a catalyst system.

Abstract: A method for producing a fuel oil includes the steps of (1) bringing a sulfur-containing feedstock oil and an alkali metal into contact for a pre-reaction to obtain a pre-reaction material, wherein the pre-reaction is performed under hydrogen-free conditions; (2) bringing the pre-reaction material into contact with a hydrogen-supplying agent for a hydrogenation reaction; and (3) separating the material obtained in step (2) to obtain a liquid-phase product fuel oil and a solid mixture. Using this method, inferior and cheap feedstock oils, such as heavy residual oils, can be converted into fuel oils.
