The reaction of methoxymethyl radicals with oxygen was studied to understand dimethyl ether (DME) oxidation. Results show a preference for thermal decomposition, offering insights for optimizing solid oxide fuel cell performance.

Area of Science:

  • Chemical Kinetics
  • Combustion Chemistry
  • Fuel Science

Background:

  • Dimethyl ether (DME) is a promising alternative fuel for diesel engines and solid oxide fuel cells.
  • Understanding DME's oxidation chemistry is crucial for its efficient application.
  • The reaction between methoxymethyl radicals and oxygen is a key step in DME oxidation.

Purpose of the Study:

  • To investigate the reaction pathways and kinetics of methoxymethyl radicals with O(2).
  • To determine the branching ratio for the CH(3)OCH(2) + O(2) reaction.
  • To provide data for optimizing DME utilization in fuel cells.

Main Methods:

  • Real-time kinetic measurements using transient infrared spectroscopy.
  • Monitoring the yield of formaldehyde, methyl formate, and formic acid.

    • Main Results:

    • The branching ratio was determined as a function of temperature and pressure.
    • The rate constant for the methoxymethyl peroxy radical self-reaction was calculated.
    • A strong preference for thermal decomposition of alkoxy radicals over reaction with O(2) was observed.

    Conclusions:

    • The study elucidates the oxidation pathways of DME under specific conditions.
    • Findings suggest that thermal decomposition is favored over O(2) reaction for alkoxy radicals.
    • This research can inform the optimization of solid oxide fuel cell operation with DME.
