Detoxification of hazardous waste streams using microwave-assisted fluid-bed oxidation

Microwave-assisted oxidation of trichloroethane (TCE) performed at 500-580{degree}C has been found to be significantly more efficient than conventional oxidation methods. Experiments were conducted using a 6 kilowatt, 2.45 gigohertz power supply and a 6 inch bed of silicon carbide granules in a 1 inch diameter quartz reactor tube which in turn was placed in a microwave cavity. After heating the reactor to a given temperature a TCE-air stream was passed through the silicon carbide bed. TCE was almost completely detoxified (98--99%) in a single pass through the silicon carbide bed at 500--580{degree}C. The oxidation products are HCl, CO{sub 2} and CO. By comparison the corresponding single-pass detoxification using conventional thermal methods results in only partial conversion. The principal products being dichloroethylene (C{sub 2}H{sub 2}Cl{sub 2}) and HCl. 5 refs., 1 tab.
