Reagent grade liquid ethanol and dimethyl disulfide were injected into the VOC generator, which was kept at a constant temperature of 30°C in the water bath. Purged N, carried the vaporized VOC to mix with diluted air and N, in the
mixture to simulate the waste gas, from a typical petrochemical plant, at a certain flow rate and 0, concentration. The simulated gas was injected into the catalytic reactor heated by a electrical furnace. One millilitre of gas samples were taken before and after the reaction by an on-line autosampler to be injected into the GC to determine the conversion of the VOC. The gas samples before and after the reaction were also analyzed by four gas analyzers to determine the extent of complete oxidation.
