This investigation focuses on the oxidation of chlorobenzene izn a laboratory-scale molten salt reactor. A Fourier transform infrared spectrometer with a long-path cell is used to monitor the organic waste oxidation process, including the formation of by-products as a function of temperature. The measured oxidation by-products are compared with results reported in the literature and are obtained in a combustion-driven flow reactor at similar oxidation temperatures; the results are modeled using detailed chemical kinetics. The results outlined in this work provide a direct comparison of the effectiveness of molten salt oxidation compared with conventional combustion oxidation and highlight the advantages and disadvantages associated with the molten salt oxidation process.
