Abstract:
The applicable O3 oxidation mechanism for simultaneous desulfurization and denitrification is of great significance in the research on integrated removal technology for ship exhaust pollutants. Based on the minimized reaction network (MRN) method, the reaction mechanism for ozone (O3) oxidation desulfurization and denitrification is established in this study. First, a minimal reaction mechanism for O3 self-decomposition involving 5 species and 5 reactions is established. Then, based on this O3 self-decomposition reaction mechanism, 17 nitrogen-containing species and 26 nitrogen-related reactions are added to form the reaction mechanism for O3 oxidation denitrification. Finally, 2 sulfur-containing species and 2 sulfur-related reactions are added to the O3 oxidation denitrification reaction mechanism to construct the complete minimal reaction mechanism for O3 oxidation desulfurization and denitrification. Therefore, the reaction mechanism includes 24 species and 33 reactions. The reliability and practicality of the reaction mechanism are verified by comparing the numerical simulation results under different operating conditions with findings from different researchers.

Rate-Determining Steps
In a multistep reaction mechanism, one of the elementary steps progresses significantly slower than the others. This slowest step is called the rate-limiting step (or rate-determining step). A reaction cannot proceed faster than its slowest step, and hence, the rate-determining step limits the overall reaction rate.
The concept of rate-determining step can be understood from the analogy of a 4-lane freeway with a short-stretch of traffic-bottleneck caused due to...
