Hydrogenation method for production of high quality middle distillate oil

The invention relates to a hydrogenation method for production of high quality middle distillate oil. The method consists of: adding fresh raw oil into a hydrogenation reactor I and a hydrogenation reactor II in a cocurrent flow way; filling the hydrogenation reactor I with an amorphous hydrocracking catalyst, and filling the hydrogenation reactor II with a molecular sieve hydrocracking catalyst; separating the reaction effluent of the hydrogenation reactor I to obtain light distillates and tail oil distillates; and bringing all or part of the tail oil distillates into the hydrogenation reactor II, and introducing the reaction effluent of the hydrogenation reactor II and part of the raw oil into the hydrogenation reactor I together. The method provided by the invention is in favor of enhancing the yield of the middle distillate oil, increasing the overall reaction space velocity, reducing the reactor volume of the whole equipment, thus lowering the investment.
