TPO analyses were performed in a TPD/TPR 2900 (Micromeritics) equipment with a thermal conductivity detector a trap for sulfur compounds and a Pt/Silica bed for oxidation of CO and hydrocarbons to CO2. Eurthermore, it has a cold trap (isopropyl alcohol/liquid nitrogen) to condense CO2 and residual moisture. The combustion products are passed through the previous traps connected in series in order to remove other compounds different from O2 in the carrier gas. This ensures that the conductivity changes observed in the detector are attributed exclusively to changes in oxygen concentration in the carrier gas. 

THERMAL CONDUCTIVITY OF LIQUID HYDROCARBONS OF THE METHANE SERIES. 

The fluid properties for the three processes may be considerably different. The CCC process uses a low pH solution (containing water and the acid product) whereas both DCL and FTS use hydrocarbon like liquids. Physical properties such as surface tension, viscosity, specific heat and thermal conductivity for these two cases may be quite different. Since the FTS is a very energetic process, the reactor may also contain some internals such as heat exchangers (cooling coils) etc. Some physical and thermal properties for these systems are outlined in Table 2.
