NOVELTY - A two-stage hydrogenation method involves utilizing hydrogenation catalyst followed by passing biological oil raw material and hydrogen through a first stage hydrogenation reaction zone containing two hydrogenation reactors to obtain a mixture. The mixture is passed through a low temperature operation reactor. The resultant mixture is passed through a high temperature operation reactor to obtain hydrogenation effluent-I, gas phase-I and liquid phase-I. The gas phase-I is recycled to first stage hydrogenation reaction zone.    USE - Two-stage hydrogenation method for producing low freezing point motor fuel.    ADVANTAGE - The method enables producing low freezing point motor fuel with high quality, increased activity stability of the catalyst and high stability.    DETAILED DESCRIPTION - A two-stage hydrogenation method involves utilizing hydrogenation catalyst followed by passing biological oil raw material and hydrogen through a first stage hydrogenation reaction zone containing two hydrogenation reactors to obtain a mixture. The mixture is passed through a low temperature operation reactor. The resultant mixture is passed through a high temperature operation reactor to obtain hydrogenation effluent-I, gas phase-I and liquid phase-I. The gas phase-I is recycled to first stage hydrogenation reaction zone. The liquid phase-I is transferred to second stage hydrogenation modification reaction zone with circulating air and hydrogenation modification catalyst followed by separating hydrogenation effluent-II, gas phase-II and liquid phase-II. The gas phase-II is recycled to the second stage hydrogenation modification reaction zone. The liquid phase-II is subjected to fractional distillation to obtain naphtha and low freezing point diesel oil followed by maintaining hydrogen sulfide content of sulfur-containing material in the first stage hydrogenation reaction zone, where the hydrogenation catalyst utilizing in the first stage hydrogenation reaction zone comprises active component comprising tungsten, molybdenum, nickel and cobalt in a vulcanized state, and the hydrogenation catalyst utilizing in the second stage hydrogenation reaction zone comprises active component comprising platinum and/or palladium in a reduction state.
