High-Pressure Study of Methyl Formate Oxidation and Its Interaction with NO

An experimental and modeling study of the influence of pressure on the oxidation of methyl formate (MF) has been performed in the 1–60 bar pressure range, in an isothermal tubular quartz flow reactor in the 573–1073 K temperature range. The influence of stoichiometry, temperature, pressure, and presence of NO on the conversion of MF and the formation of the main products (CH 2 O, CO 2, CO, CH 4, and H 2 ) has been analyzed. A detailed kinetic mechanism has been used to interpret the experimental results. The results show that the oxidation regime of MF differs significantly from atmospheric to high-pressure conditions. The impact of the NO presence has been considered, and results indicate that no net reduction of NO x is achieved, even though, at high pressure, the NO–NO 2 interconversion results in a slightly increased reactivity of MF.
