THE OXIDATION OF CARBON MONOXIDE/METHANE MIXTURES IN SHOCK WAVES.
Abstract
CO/O2/Ar mixtures with mole fractions of 4%/2%/94% and containing 180 or 500 ppm CH4 were investigated in incident shock waves at about 5 x 10 to the 17th particles/cc total concentration. The reaction was followed by measuring infrared emissions from CO2 and CO for about 1500 microsec particle time over the temperature range 1750 -2575K. The rate of CO2 production initially increased exponentially and then became constant after several percent conversion. It was possible to quantitatively describe the observations in terms of a mechanism. Methane was found to be more effective than either H2 or H2O in promoting the branching chain oxidation of CO. Extending these observations, it is shown that extremely small concentrations of organic compounds can strongly influence many features of the CO/O2 system. (Author)
