Simultaneous absorption of SO2 and NO from flue gas using ultrasound/Fe2+/heat coactivated persulfate system

In this article, a novel technique on removal of elemental mercury (Hg0) from flue gas by thermally activated ammonium persulfate ((NH4)2S2O8) has been developed for the first time. Some experiments were carried out in a bubble column reactor to evaluate the effects of process parameters on Hg0 removal. The mechanism and kinetics of Hg0 removal are also studied. The results show that the parameters, (NH4)2S2O8 concentration, activation temperature and solution pH, have significant impacts on Hg0 removal. The parameters, Hg0, SO2 and NO concentration, only have small effects on Hg0 removal. Hg0 is removed by oxidations of (NH4)2S2O8, sulfate and hydroxyl free radicals. When (NH4)2S2O8 concentration is more than 0.1 mol/L and solution pH is lower than 9.71, Hg0 removal by thermally activated (NH4)2S2O8 meets a pseudo-first-order fast reaction with respect to Hg0. However, when (NH4)2S2O8 concentration is less than 0.1 mol/L or solution pH is higher than 9.71, the removal process meets a moderate speed react...

Adsorption of CO2 from flue gas by novel seaweed-based KOH-activated porous biochars

A novel process for NO and SO2 simultaneous removal using a vacuum ultraviolet (VUV, with 185 nm wavelength)-activated O2/H2O/H2O2 system in a wet VUV–spraying reactor was developed The influence of different process variables on NO and SO2 removal was evaluated Active species (O3 and ·OH) and liquid products (SO32–, NO2–, SO42–, and NO3–) were analyzed The chemistry and routes of NO and SO2 removal were investigated The oxidation removal system exhibits excellent simultaneous removal capacity for NO and SO2, and a maximum removal of 968% for NO and complete SO2 removal were obtained under optimized conditions SO2 reaches 100% removal efficiency under most of test conditions NO removal is obviously affected by several process variables Increasing VUV power, H2O2 concentration, solution pH, liquid-to-gas ratio, and O2 concentration greatly enhances NO removal Increasing NO and SO2 concentration obviously reduces NO removal Temperature has a dual impact on NO removal, which has an optimal temperat
