Comparison of hydrolysis and oxidation reactions of carbonyl sulfide on particle matter

Reactions of carbonyl sulfide (OCS) oil atmospheric particles were investigated in a flowing system using Fourier transform infrared (F-FIR) at 293 K. Results show that OCS Could he Slowly oxidized and hydrolyzed on atmospheric particles. As a simplified model. alumina (Al2O3) was used to further compare the two reactions and the results indicate that hydrolysis reaction of OCS has an advantage over oxidation reaction to take place at given time and that heterogeneous reactions of OCS on particles at atmospheric conditions may include oxidation and hydrolysis reactions. To explore the effect of metals oil hydrolysis reaction, zinc (Zn), iron (Fe), calcium (Ca), and magnesium (Mg) Supported oil Al2O3 were prepared by incipient wetness method, and the results suggest that all metal oxides significantly enhance the initial intrinsic activity of OCS when compared with unmodified Al2O3. The Zn-modified Al2O3 gives a significant increase of CO2 produced throughout the time-scale of these experiments and the possible reaction processes are proposed.
