Carbon-enriched coal fly ash was evaluated in this work as a low-cost adsorbent for SO2
removal from stack gases. The unburned carbon in coal fly ash was concentrated by
mechanical sieving and vegetal oil agglomeration. The carbon concentrates were
activated with steam at 900ºC in order to develop porosity onto the samples. The
performance of these samples in the SO2 abatement was tested in the following
conditions: 100ºC, 1000 ppmv SO2, 5% O2, 6% water vapor. A good SO2 removal
capacity was shown by some of the studied samples that can be related to their textural
properties. Cycles of SO2 adsorption/regeneration were carried out in order to evaluate
the possibility of thermal regeneration and re-use of these carbons. Regeneration of the
exhausted carbons was carried out at 400ºC of temperature and a flow of 25 ml/min of
Ar. After each cycle, the SO2 removal capacity of the sample decreases. |
