HIGH-PRESSURE OXIDATION OF NORMAL-DECANE AND KEROSENE IN DILUTE CONDITIONS FROM LOW TO HIGH-TEMPERATURE

The oxidation of n-decane in a high-pressure jet-stirred reactor (JSR) has been investigated experimentally in a wide range of conditions co vering the low and high temperature oxidation regimes (550-1150K, 10at m, phi=0.1 to 1.5). The oxidation of kerosene TRO has been investigate d in the same conditions of temperature and equivalence ratio and for pressures ranging from 10 to 40atm. Reactants, intermediates and final products have been measured for the oxidation of the two fuels. Cycli c ethers resulting from the cool flame of n-decane were identified. At 10atm, the present study shows that the oxidation of n-decane is simi lar to that of kerosene TRO. The results are interpreted in terms of r eaction mechanism. A detailed chemical kinetic modeling of the high-te mperature oxidation of n-decane is used to assess the influence of low temperature chemistry in the intermediate temperature range and is us ed to represent kerosene oxidation in a JSR.
