1. a highly unsaturated compounds is selected the processing method of hydrogenation, and it comprises the steps:

  • (a) (1) being contained the hydrocarbon material flow of the highly unsaturated compounds that comprises diolefine and alkynes and (2) contains the logistics of hydrogen and adds a distillation column reactor;

    (b) under reaction and distillatory condition, under at least about the effective hydrogen partial pressure of 0.1psia to the scope that is lower than 70psia, in above-mentioned distillation column reactor, carry out simultaneously;

    (i) in the distillation reaction district above-mentioned logistics is contacted with the hydrogenation catalyst that is made into the distillation structure pattern, with described hydrogen the part of above-mentioned highly unsaturated compounds is selected hydrogenation thus, in blended vapour/liquid phase, in reaction mixture, generate low unsaturated hydrocarbons and(ii) the low unsaturated hydrocarbons of the described generation of described selection hydrogenation generation is separated from above-mentioned reaction mixture, will be comprised a part of condensation of the described hydrocarbon of described highly unsaturated compounds simultaneously by fractionation in described distillation structure.
