Abstract
Poly(oxymethylene) dimethyl ethers (POMDME) with the general chemical formula of CH3O (CH2O)n CH3 ( n > 1) are promising oxygenated alternative fuels with great soot-reduction potential. Combustion kinetics of the compound with n = 3 POMDME3[CH3O(CH2O)3CH3] was examined with combined experimental and modeling approached. Twenty-six species including some radicals and reactive intermediates were distinguished and quantified in a low-pressure laminar premixed POMDME3 flame with a synchrotron vacuum ultraviolet photoionization mass spectrometry. A kinetic model to interpret the high-temperature combustion chemistry of POMDME3 was constructed and tested by all the measurements with uncertainties of both experiments and model predictions. The consumption processes of POMDME3 and the formation mechanisms of some crucial intermediates are considered.
