THE OXIDATION OF CARBON MONOXIDE BY OXYGEN IN SHOCK WAVES.

The oxidation of CO, with and without small amounts of added hydrogen, was investigated in very dilute mixtures with argon. The reaction was followed in incident shock waves by measuring CO and CO2 infrared emissions for about 2000 micro sec particle time over the 1700 to 2300K range. The reaction shows an initially increasing exponentially in many runs rate followed, under most conditions, by a period of constant rate. The observed CO2 concentration - time profiles were compared to those calculated numerically on a computer. These calculations used two mechanisms, proposed by others, for the shock tube oxidation of CO. The level of impurities in gases used was extensively investigated. Relation of the presently reported data to those of others is discussed. Author
