Absorption of NO from simulated flue gas by using NaClO2/(NH4)2CO3 solutions in a stirred tank reactor
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.
