ABSTRACT:
This invention relates to absorbents which are particularly useful for the treatment of sulphur-containing oxides. These absorbents are made from materials containing aluminium oxide by steps including leaching an oxide-containing material, such as bauxite, with an alkaline solution; separating the resultant leach liquor; and drying the liquor. If desired alkali metal carbonate may be added to the liquor between the steps of separation and drying.
