Thermal decomposition of SRC-II middle distillate under surface vaporizing conditions

Decomposition of SRC-II middle distillate under surface vaporizing conditions was studied as a function of temperature (heating rate), vapour phase residence time and oxygen level.

Description
Summary:Decomposition of SRC-II middle distillate under surface vaporizing conditions was studied as a function of temperature (heating rate), vapour phase residence time and oxygen level. The stressed and unstressed fuel was analysed by capillary gas chromatography. Decomposition was found to be greatest at low temperature. Boiling mode did not appear to affect the extent of decomposition. Decomposition was weakly related to chemical class and strongly related to component volatility. The effect of gas phase residence time and oxygen level were negligible at the conditions studied. It is concluded that decomposition occurs primarily within the liquid and at the vaporizer surface.
