Abstract

A material for absorbing carbon dioxide is obtained by mixing slaked lime and an aqueous solution of sodium acetate, agglomerating the mixture into granules, or tablets, and calcining the product at a temperature above the melting point of sodium acetate but below the temperature at which lime is dehydrated and anhydrous sodium acetate is decomposed. A suitable temperature is 350--380 DEG C. The agglomerated mixture may be partially dried by storing at 110 DEG C. before the calcination. The calcination may take place in a rotary furnace. Before use the calcined product is moistened with an aqueous solution of a non-volatile caustic alkaline substance, eg. caustic soda.ALSO:A material for absorbing carbon dioxide for use in respiratory appliances is obtained by mixing slaked lime and an aqueous solution of sodium acetate, agglomerating the mixture into granules or tablets, and calcining the product at a temperature above the melting point of sodium acetate but below the temperature at which the lime is dehydrated and anhydrous sodium acetate is decomposed. A suitable temperature is 350-380 DEG C. The agglomerated mixture may be partially dried by stoving at 110 DEG C. before the calcination. The calcination may take place in a rotary furnace. Before use the calcined product is moistened with an aqueous solution of a non-volatile caustic alkaline substance, e.g. caustic soda.
