The present studies deals with the adsorption of SO2 by manganese oxide i.e., Pyrulusite ore. Pyrulusite is used as an adsorbent for the present studies. It is found that the percentage removal of SO2 increases with the increase in contact time, follows first order kinetics and a unimolecular layer is formed during the process. The percentage removal of SO2 increases with increase in dosages an...

The removal of SO2 in the presence of alkene-ozone systems has been studied for ethene, cis-but-2-ene, trans-but-2-ene and 2,3-dimethyl-but-2-ene, as a function of humidity, under atmospheric boundary layer conditions. The SO2 removal displays a clear dependence on relative humidity for all four alkene-ozone systems confirming a significant reaction for stabilised Criegee intermediates (SCI) wi...

Aiming at NOx (NO 90%, NO2 10%) and SO2 in simulated vessel emissions, denitration desulfurization were studied through ozone oxidation combined with seawater as absorbent. Specifically, the different influencing factors of analyzed. The results indicated that efficiency NO can reach over 90% when molar ratio O3/NO is 1.2. Ozone washing same unit decrease temperature NO, avoid high decompositio...
