Abstract

The conversion of trichloromethane in mixtures with air was investigated under normal pressure in a gliding discharge (GD) reactor operated in both a homogeneous gas system and with a solid catalyst. The Pt catalyst supported by a honey-comb cordierite structure was placed in the reactor below the ends of the electrodes. Cl2 and HCl were the main products of the CHCl3 conversion. The presence of CCl4 was also noted. The influence of the electrode length and the distance between the electrodes in the narrowest section on CHCl3 conversion was examined. The Pt catalyst revealed some activity in the trichloromethane processing. This resulted in an increased overall CHCl3 conversion with the portion of CHCl3 converted to CCl4 smaller than that in the homogeneous system. The effect of temperature on CHCl3 conversion was found to be significant.
