FIELD: chemistry.SUBSTANCE: invention can be applied in chemical industry. Method of removal of sulfur-, nitrogen- and halogen containing admixture, present in synthesis-gas, such, as HS, COS, CS, HCN, NH, HF, HCl, HBr and HI, contains: a) stage of combined hydrolysis of COS and HCN and catching halogenated compounds with application of TiO-based catalyst which contains from 10 wt % to 100 wt % of TiOand from 1 wt % to 30 wt % of at least one sulfate of alkali-earth metal, selected from calcium, barium, strontium and magnesium, b) stage of washing with at least one solvent, c) stage of desulphurisation on catching mass or adsorbent.EFFECT: invention makes it possible to obtain purified synthesis-gas, which contains less than 10 weight parts per billion of sulphureous admixtures, less than 10 weight parts per billion of halogenated admixtures.22 cl, 8 tbl, 6 ex |
