Abstract:
     The process comprises mixing at least one of decomposable compounds selected from 2B and 3B groups of periodic table with hydrocarbon-containing raw material stream and making the stream containing the decomposable compounds described above contact with a catalyst composition consisting of carrier and promotor during the hydrogenation and purification, the former can be selected from Al2O3. SiO2 and Si-Al and the later contains at least one of metals selected from 4B. 7B and 8 groups of periodic table, when the fresh catalyst is partially deactivated or loses efficacy partially, it is time to begin to add the decomposable compound.
Time: 9
