- Abstract
- The urgency of reducing the emission of greenhouse gases and achieving a circular carbon economy encourages research on renewable energy systems. The alternative synthetic fuels (power to liquids) could be high-potential energy carriers for longdistance transportation and long-term storage [1, 2]. Oxymethylene ethers (OMEs), formally known as polyoxyethylene dimethyl ethers, with the structural formula of CH3O(CH2O)nCH3, are regarded as a potential asset for the energy transition and valuable candidates for power to liquids thanks to their high energy density [3, 4]. A deep understanding of oxidation kinetics of OMEs remains a prerequisite for optimizing their combustion and for a comprehensive assessment of the future engine application potential of OMEs. Few detailed studies have been conducted on longer-chain OMEs (OMEn, n>1) [5-8]. The purpose of this work is to investigate the combustion chemistry of OME1 and OME2 under stoichiometric and fuel-lean conditions and develop a detailed mechanism including OME1-2. The experimental study of OME1 and OME2 combustion was performed in the shock tube at high pressures and in laminar flames at low pressure by carrying out flame structure measurements with molecular-beam mass spectrometry (MBMS).
