Sandia CRF team provides experimental confirmation of oxidation scheme of lower emissions diesel alternative DME; new intermediates 17 October 2015 An international team of researchers led by a group from the Combustion Research Facility (CRF) at Sandia National Laboratories recently provided experimental confirmation of the generally accepted low-temperature oxidation scheme of dimethyl ether (DME)—a lower soot and emissions alternative to diesel—at low temperatures (~540 K, 267˚C). Their paper was published in the ACS Journal of Physical Chemistry A . Especially significant, they said, was detecting and identifying keto-hydroperoxide (hydroperoxymethylformate, HPMF, HOOCH2 OCHO)—a previously undiscovered partially oxidized intermediate—thereby providing critical information needed to improve models. … because innovative engine designs like homogeneous charge compression ...
