PROCESS FOR TREATING GASES OBTAINED BY COAL GASIFICATION, RESIDUE GASIFICATION, REFUSE GASIFICATION OR OIL GASIFICATION

摘要

The present invention relates to a kind of techniques, for treating the synthesis gas or fuel gas that are obtained by coal gasification, residue char, gasification or Waste oil gasification, wherein air-flow is obtained by gasification, containing being reduced and possible inert gas treatment, for desulfurization, optionally in the synthesis of separation product or combustion gas, then hydrogenate, sulphur compound is still present in air-flow, to be to be converted into hydrogen sulfide, hydrogen sulfide is removed through absorption or is absorbed from gas stream, in solid or liquid absorbent and loads adsorbent supply, coal, slag, rubbish, or oil with gasified.
