摘要
Catalytic combustion can improve the combustion efficiency of aviation kerosene, and the small molecule gas generated by catalytic combustion plays an important role in the ignition and combustion characteristics of aviation kerosene in the later stage. As an alternative fuel of aviation kerosene, n-decane was taken as the research object. The characteristics of catalytic combustion and its gaseous products were studied. The comparative experiments of catalytic/non-catalytic combustion on Pt/ZSM-5 and quartz were performed. The effects of temperature (100~600℃), equivalent ratio (Φ=0.6, 1.0, 2.0) and catalyst (Pt/ZSM-5) on n-decane conversion and gaseous products characteristics were analyzed in the experiment. On the Pt catalysis conditions, the light-off temperatures of n-decane are reduced by about 110℃. The catalytic reaction achieves high conversion at about 200℃: when Φ=0.6~1.0, the conversion is above 75%. Furthermore, the CO content is reduced significantly in catalytic reaction and the conversion of n-decane and the degree of complete oxidation increased. In the range of Φ=0.6~2.0, CO2 is the main gaseous product. The reaction of catalytic cracking of n-decane to butene at low temperature (<150℃) has an important effect on the start of the catalytic reaction. On the fuel-rich conditions, the transformation of hydrocarbon gaseous products from C3, C4 macromolecules to C1, C2 micromolecules and the gaseous oxidation products from CO2 to CO are two important characteristics of the n-decane catalytic reaction at high temperature (>500℃). © 2021, Editorial Department of Journal of Propulsion Technology.
