Removal Of So2

Experiments of simultaneous removal of SO2 and NO from simulated flue gas, using NaClO2 solution as the absorbent, were carried out in a self-designed bubble reactor, and removal efficiencies of 100 percent for SO2 and 95.2 percent for NO were obtained under the optimal experimental conditions. The mechanism of simultaneous removal of SO2 and NO using NaClO2 acid solutions was proposed by analyzing the removal products. The reaction kinetics for simultaneous desulfurization and denitrification were investigated, and the results indicated that the oxidation-absorption processes of SO2 and NO were divided into two zones, as the fast and slow reaction zones. In the slow reaction zones, both were zero order reactions, and in the fast reaction zones, the reaction order, rate constant and activation energy of SO2 removal reaction with absorbent were 1.4, 1.22 (mol L-1)-0.4 s-1 and 66.25 kJ mol-1, respectively, and 2, 3.15×103 (mol L-1)-1 s-1, and 42.50 kJ mol-1 for NO removal reaction, respectively.

Nitrogen oxides are removed from the troposphere through the reactive uptake of N2O5 into aqueous aerosol. This process is thought to occur within the bulk of an aerosol, through solvation and subsequent hydrolysis. However, this perspective is difficult to reconcile with field measurements and cannot be verified directly because of the fast reaction kinetics of N2O5. Here, we use molecular simulations, including reactive potentials and importance sampling, to study the uptake of N2O5 into an aqueous aerosol. Rather than being mediated by the bulk, uptake is dominated by interfacial processes due to facile hydrolysis at the liquid-vapor interface and competitive reevaporation. With this molecular information, we propose an alternative interfacial reactive uptake model consistent with existing experimental observations.

<p><i>Operando</i> spectroelectrochemical analysis is used to determine the water oxidation reaction kinetics for hematite photoanodes prepared using four different synthetic procedures. Whilst these photoanodes exhibit very different current / voltage performance, their underlying water oxidation kinetics are found to be almost invariant. Lower photoanode performance was found to correlate with the observation of optical signals indicative of charge accumulation in mid-gap oxygen vacancy states, indicating these states do not contribute directly to water oxidation.</p>
