Skeleton kinetic model of acetaldehyde oxidation from comprehensive models

This work elucidated the chemical reaction scheme developed by Wang and Mou (Wang-Mou scheme) in 1985 for describing the dynamic behavior of acetaldehyde oxidized in a continuous-flow stirred tank reactor (CSTR). We deduced the Wang-Mou scheme from the more comprehensive chemical reaction schemes proposed by previous literature works (detailed scheme), and the correlation between the detailed scheme and the Wang-Mou scheme was established. Numerical simulation was adopted to explore the dynamic characteristics of the Wang-Mou scheme and compared with the experiments, revealing a reasonable agreement with the experimental findings. Finally, mechanisms responsible for various dynamic regimes were discussed. The link of the skeleton, Wang-Mou scheme, with the more comprehensive schemes was established.
