Process for regeneration and increasing the activity of activated cokes of dry flue gas desulphurisation
The invention relates to a process for regeneration with simultaneous increase in activity of activated cokes which are used in the adsorptive flue gas desulphurisation. Use of the process has the effect that the carbon losses necessarily occurring in the regeneration are reduced, the regeneration r...

| description | The invention relates to a process for regeneration with simultaneous increase in activity of activated cokes which are used in the adsorptive flue gas desulphurisation. Use of the process has the effect that the carbon losses necessarily occurring in the regeneration are reduced, the regeneration rate is improved and the activity is retained and even increased. According to the invention the regeneration is carried out with addition of an external carbon under reaction conditions known per se, as a result of the grain size, source and moisture content of the added carbon, the added carbon forming the reducing agent for the conversion of SO3 to SO2. |
