The absorption process of NO into KMnO4/(NH4) 2CO3 solutions was studied in a stirred tank reactor. The experimental results showed that the reaction process was a fast pseudo-m reaction. The reaction between NO and aqueous solutions of KMnO 4/(NH4)2CO3 was found to be first-order with respect to NO and with respect to KMnO4. The frequency factor and the average activation energy of this reaction were 2.3 × 109 m3/(mol s) and 36.77 kJ/mol, respectively. Copyright © 2012 American Institute of Chemical Engineers. Source

Experiments were performed in a stirred tank reactor to study the absorption kinetics of NO into aqueous solutions of NaClO2/(NH4)2CO3 solutions. The absorption process is a fast pseudo-reaction, and the reaction was found to be second-order with respect to NO and first-order with respect to NaClO2, respectively. The frequency factor and the average activation energy of this reaction were 4. 56×1011 m6/(mol2 s) and 33. 01 kJ/mol respectively. The absorption rate of NO increased with increasing reaction temperature, but decreased with increasing (NH4)2CO3 solution. © 2012 Korean Institute of Chemical Engineers, Seoul, Korea. Source

Absorption experiments of NO2 from simulated flue gas into aqueous (NH4)2SO3 solution were performed in a stirred tank reactor under atmosphere pressure. As can be seen from the experimental results, the absorption rate of NO2 into (NH 4)2SO3 solution increases as the (NH 4)2SO3 concentration increases from 0.01 to 0.06 mol/L. As the concentration of (NH4)2SO3 solution exceeds 0.06 mol/L, the absorption process becomes gas-film controlled. And the absorption rate increases with increasing NO2 inlet concentration but decreases with increasing reaction temperature. Compared with Na2SO3 solution, (NH4)2SO 3 solution has higher NO2 absorption rate. Copyright © 2012 American Institute of Chemical Engineers. Source
