Catalytic destruction of chlorinated aromatics (PCBs) in a fixed bed reactor

Catalytic oxidation of chlorinated hydrocarbons is a promising technology for the treatment and disposal of the worldwide surplus of polychlorinated biphenyls (PCBs). In the present study, the oxidation kinetics of 1,2-dichlorobenzene (DCB) and 1,2,4-trichlorobenzene (TCB) for temperature ranging from 350-600;The experimental data were described using a pseudo-first-order rate mechanism. A regression model, based on the experimental data, was also developed to predict the oxidation rates of the reactants. The temperature dependency of the rate constant was evaluated using the Arrhenius model. The activation energy was determined to be 11.5 and 16.8 kcal/gmol for DCB and TCB. The pre-exponential factors, K;In the fixed bed catalytic studies it was shown that DCB and TCB can essentially be completely decomposed at 450...
