Abstract
A method is disclosed for regeneration of carbonaceous adsorbent comprising the steps of: a) providing a carbonaceous adsorbent comprising Sulphur contaminants, b) pyrolysing of the absorbed Sulphur contaminants thereby generating pyrolysis gases containing SO2, c) burning off the pyrolysis gases in an incinerator thereby obtaining flue gases containing SO2, d) cooling the flue gases, and e) removing dust from the flue gases and reacting SO2 contained in the flue gases with calcium hydroxide and/or calcium carbonate thereby producing calcium sulphite.
