Abstract : A reactor and its associated peripherals were designed to be an integral part of the System for Thermal Diagnostic Studies (STDS), a versatile mainframe thermal system. The Condensed Phase Test Cell (CPTC) can be used to conduct experiments for flowing liquids at temperatures up to approximately 800 deg C and pressures up to 1500 psig. In the area of thermal stability, the CPTC can be used to conduct flowing experiments on jet fuels, jet fuel candidates and model mixtures at both subcritical and supercritical conditions. By subjecting condensed phase liquids to controlled conditions of temperature, pressures, reactive atmosphere (dissolved oxygen concentration) residence time and distribution, etc., thermal degradation experiments coul be conducted. Product distributions from the exposure of liquid phase and condensed phase material were performed via high pressure liquid sampling valves in line with gas chromatography-mass spectrometry (GC-MS); thus, technique is capable of measuring dissolved fixed gases (nitrogen, oxygen, argon, carbondioxide, etc.), cracking gases (methane, ethane, ethylene, propylene, etc.) and thermal reaction products of the parent material.
