| abstract | A method of removing organically or inorganically combined sulphur from a gas containing CO and/or H2 and/or a hydrocarbon, comprises adjusting the dew point to at least 15 DEG C. by adding water or steam and oxidizing the sulphur compounds between 300-600 DEG C. in the presence of an alkaline earth metal compound which is effective to absorb or combine with sulphur oxides under the conditions employed during the oxidation. Oxides, hydroxides and carbonates of Mg, Sr, Ba and preferably of Ca, alone or in mixtures of two or more are mentioned, and alkali metal compounds, preferably of K or Na, may be added as activators. Carrier materials mentioned are synthetic Al silicates, Al oxides, and diatomaceous earth, e.g. kieselguhr. Oxygen present in the gas may be relied on for oxidation, or air may be added, and if the alkaline earth metal compound is in two stages in series, air may be added before each stage, the oxygen content by volume of the gas being raised to 1%. A pressure range of 0.5 to 50 atmospheres is mentioned for the oxidation reaction, and gases referred to include coke oven gas, water gas and producer gas. If the gas is predominantly hydrocarbon, organic sulphur compounds may be catalytically converted to H2S before the main purification step, e.g. with Co-Mo, Co-W, Ni-Mo, NiS catalysts. Fixed or fluidized beds may be employed for the alkaline compounds, and the steam and water added to the gas may increase the volume proportion of water vapour to gas to 1:1 or even 2:1. A comparative example is described. |
