Abstract: 1,142,339. Removing CoS from light hydrocarbons. BADISCHE ANILIN- & SODAFABRIK A.G. 17 June, 1966 [19 June, 1965], No. 27166/66. Heading C5E. Carbon oxysulphide is removed from mixtures of liquid C 3 -hydrocarbons, such as are obtained by cracking gaseous and/or liquid hydrocarbons, by passing the mixture in the liquid phase over a substance containing at least one of the oxides of cadmium, zinc, nickel or cobalt deposited on or mixed with a carrier of large specific internal surface area such as silica gel, active alumina, pumice or magnesium silicate to give a porous composition. The preferred substance has pores of diameter 50-150 Š and contains 10-70% by weight oxide, particularly 30-60% cadmium oxide. The carrier may be loaded by treatment with a saturated aqueous solution of a readily decomposable metal salt e.g. an acetate and heating in air below 400‹ C., or the oxide and carrier may be mixed, pressmoulded and if desired, roasted. The purification may be effected at 10-45 atmos. and 20-60‹ C. to reduce the CoS content of, for example, C 3 mixtures containing propyne or propadiene to less than 1 p.p.m.
