Abstract
Town gas containing less than 10% CO is purified by heating with H2S or S the H2S may be that present in the gas to form COS which is then reacted with NH3 to form urea. The term town gas includes illuminating gas and coke works gas. The heating can be at 200-1200 DEG C. for 0.01-100 seconds in the presence of catalysts, e.g. Al2O3, silica gel or pumice stone. These catalysts can be coated with a Group VI metal oxide or sulphide, e.g. of W and/or Mo, and a Group VIII metal can also be present. H2S formed by reaction of COS with NH3 can be recycled. The COS can be washed out of the gas with a solvent in which it is reacted with NH3, or the gas can be cooled with or without the use of pressure to separate the COS for further processing, or the COS + NH3 reaction can be carried out in the gas phase on porous catalysts e.g. active carbon.ALSO:Town gas containing less than 10% CO is purified by heating with H2S or S to form COS which is then reacted with NH3 to form urea.
