Abstract
A study on the removal of polychlorinated biphenyls in waste insulating oil by using a chromium oxide catalyst was conducted through changing catalyst reaction temperatures, air injection rates and concentrations of polychlorinated biphenyls. As a result of this study, in the case of using chromium oxide as a catalyst in reductive dechlorination, treatment of high concentrations (over 1,000 ppm of polychlorinated biphenyls) contained in waste insulating oil was possible. Also, the optimal reaction conditions were the reaction temperature 400 °C of the tubular reactor (diameter 5 cm, length 30 cm, catalyst 400 g), air injection rate 400 mL/min and insulating oil injection rate 5 mL/min. As it is possible to treat high concentrations of over 1,000 ppm of polychlorinated biphenyls contained in waste oil when using a chromium oxide catalyst in reductive dechlorination mechanism by utilizing the efficiency, it is considered to be usable for continuous and movable multi-stage reactors.
