摘要：

The actual combustion process of aviation kerosene often has high stoichiometric ratio (Φ) oxygen-lean conditions. In this paper, n-decane was used as a one-element alternative fuel of aviation kerosene, and the oxygen-depleted catalytic/non-catalytic combustion characteristics of n-decane in micro tube with Pt/ZSM-5 catalyst or quartz sand packed bed were experimentally studied under oxygen-lean conditions (Φ=2-4). The effects of equivalence ratio (Φ=2-4), temperature (300-450℃) and catalyst on the conversion rate of n-decane, combustion efficiency and gas phase product distribution were analyzed. The results showed that the Pt/ZSM-5 catalyst had an obvious promotion effect on the combustion reaction of n-decane, and there was a phenomenon of temperature surge. When the equivalence ratio Φ increased from 2 to 3.5, the dynamic ignition point rised from 196℃ to 271℃; while without catalysis, there was no obvious point of ignition. The conversion rate of n-decane under the oxygen-lean catalysis condition was always lower than that under the no catalysis condition, but the combustion efficiency was significantly higher than that under the no catalysis condition. The main gas-phase product of catalytic combustion of n-decane was CO2, and the main gas-phase product without catalysis was CO and olefins. © 2022, Chemical Industry Press Co., Ltd.
