Objective
This proposal aims at the flue gas desulphurization using calcium doped activated carbon under Iox temperature conditions and aIIowing the recovery of S02.
The reduction of sulphur emissions using calcium oxide is normally operated at high temperatures. ObviousIy there is a reaction between CaO and SO2 at lower temperatures (below 4OO°C), forming CaSO3. Due to the relatively low CaO surface, the effect is not essential, but can be enhanced by doping activated carbon with calcium. The CaOSO2/carbon system, which is formed, can be regenerated at temperatures below 600°C. The SO2 rich gas can be used for the production of H2S04 or elemental sulphur.
Trials will be carried out in two steps:
- in the laboratory scale
This activity will cover:
. preparation of activated carbons, appropriate for the maximum load of active CaO;
. investigation of different methods to ntroduce the calcium (e.g. impregnation);
- analysis of the retention process;
- analysis of the regeneration process;
- investigation into possible SO2/carbon reactions during regeneration;
- in the pilot plant scale
. sample preparation (large amounts, using the best experimental conditions found In the laboratory trials);
. continuous trials In the pilot reactor, paying special attention to the SO2 reduction in a simulated power station flue gas;
. trials on CaSO3 decomposition in order to analyse the regenerability of the doped activated carbon.
