The invention relates to a hydrogenation method for high- quality catalytic
cracking material. It comprises: carrying out hydrogenation and modifying reaction for mixture of raw oil and
hydrogen gas in hydrogenation
preservative, any hydrogenation demetalation catalyst and hydrogenation treating catalyst in turn; and the filling volumetic percentage of mentioned
preservative and catalyst are 2- 15%, 0- 30% and 55-95%, cooling reactant and separating and getting a large amount of refined gas oil fraction, part of low-sulphur diesel fraction and little amount of benzine
naphtha fraction, and the refined gas oil fraction is the catalytic
cracking material. The invention can prolong the operation cycle for device under high percentage of desulfurization, the activity of employed catalyst is high, and the rational
packing method ensures better catalyst activity, and reduces production cost. The invention is characterized by simple process, low operation pressure, low device investment and operation cost.
