Date Sep. 21, 1995Absorbents, suitable for absorbing sulphur compounds such as hydrogen sulphide from gases and liquids, in the form of shaped units having an average size within the range 1-10 mm and containing at least 75% by weight of an absorbent material comprising copper carbonate, basic copper carbonate, and/or copper hydroxide. The units preferably have a bulk density of at least 0.9 kg/l, especially at least 1.2 kg/l. The units are preferably agglomerates containing a small amount of a binder such as a cement and may also contain a proportion of alumina to catalyse hydrolysis of carbon-containing sulphur compounds such as carbonyl sulphide or carbon disulphide. |
