Abstract
The pyrolysis and oxidation of dimethyl ether (DME) and its mixtures with methane were investigated at high pressures (50 and 100 bar) and intermediate temperatures (450–900 K) in a laminar flow reactor. DME pyrolysis started at 825 K (at 50 bar). The onset of DME reaction was detected at 525–550 K (at 50 bar), independent of stoichiometry. The negative temperature coefficient (NTC) zone in the DME profile always included temperatures of 575–625 K. A profound promoting effect of DME addition on the ignition of methane was observed as the onset of reaction was shifted to lower temperatures by 50–150 K (at 100 bar).
