Abstract (en)
[origin: CA2687996A1] The invention relates to a method for the treatment of raw product gas pr oduced by pressure gasification of solid fuels. After cooling to 15 to 45 øC , the following substances are removed by physisorption with cold oxygenate: in a preliminary stage, HCN and NH3; in a first stage, H2S and COS and, if necessary, other sulfurous compounds; and in a second stage CO2. The pure pr oduct gas is then conveyed as a reduction gas and/or as a combustion gas to the direct reduction of iron ore. An improvement to the method lies in the f act that the desulfurized product gas is mixed with return gas loaded with C O2 and water vapor diverted from the circulation of the return gas from the direct reduction of iron ore, once the water vapor contained therein has bee n removed.
