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 (CH2O, CO2, CO, CH4, and H2) 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 NOx is achieved,
even though, at high pressure, the NO–NO2 interconversion
results in a slightly increased reactivity of MF.
