METHOD OF REMOVAL OF SULFUR-, NITROGEN- AND HALOGEN-CONTAINING ADMIXTURES, PRESENT IN SYNTHESIS-GAS Russian patent published in 2013 - IPC B01D53/52 B01D53/68 B01D53/75 B01D53/86 C10K1/32 C10K1/34 

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 H₂S, COS, CS₂, HCN, NH₃, HF, HCl, HBr and HI, contains: a) stage of combined hydrolysis of COS and HCN and catching halogenated compounds with application of TiO₂-based catalyst which contains from 10 wt % to 100 wt % of TiO₂ and 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.
