| 中文摘要 | Measurements of kerosene conversion due to thermal cracking and mass flow rate through a sonic nozzle have been made under supercritical conditions. Based on the temperature dependency of mole fraction of gaseous products from kerosene cracking, a one-step cracking model has been proposed to correlate the kerosene conversion and the mass flow rate through a sonic nozzle. In this model, the cracked kerosene was described as a three-component ideal gas mixture (IGM) of unreacted kerosene, gaseous products after cooled to room temperature and residuals. The composition of unreacted kerosene and gaseous products were determined by a gas chromatography, while the approximate chemical formula of the residuals was derived from the average molecular weight of cracked kerosene mixture at high temperature. The mass flow rate of cracked kerosene was then calculated from ideal gas law for the three-component mixture. Agreement was obtained when comparing the calculated mass flow rate with the measurements. Kerosene residence time and the rate constant of conversion inside a heater were also discussed based on this global cracking model. |
