Abstract
Activated carbon and quicklime were used to prepare complex calcium based adsorbent for flue gas desulphurization. The desulfurization properties of adsorbent were analyzed on fixed bed. The results showed that the desulfurization effect of the composite adsorbent was best when the ratio of activated carbon to calcium was 1:2, the water heating time was 24 hours and heating temperature was 90 °C. At the same time, low temperature plasma technology is used to ionize the composite adsorbent, increase the number of surface chemical functional groups of the adsorbent, and then improve its desulfurization efficiency. The effect of modification time and power on desulfurization efficiency was studied. The results show that low temperature plasma ionization modification can obviously improve the desulfurization performance of composite adsorbent.
