Abstract: Shaped absorbent units suitable for use as chloride absorbents comprising a calcined intimate mixture of an alkali or alkaline earth, zinc and aluminium components having an alkali or alkaline earth mental to zinc atomic ratio in the range 0.5x to 2.5x and an alkali or alkaline earth metal to aluminium atomic ratio in the range 0.5x to 1.5x, where x is the valency of the alkali or alkaline earth metal, and containing from 5 to 20% by weight of a binder. Preferred compositions are made from sodium carbonate or bicarbonate, basic zinc carbonate or zinc oxide and alumina or hydrated alumina.
