| Research Abstract |
Catalytic decomposition employing uranium oxide, U_3O_8, powder was carried out for chlorobenzene as one of the toxic gases generated from the thermal treatment of low level radioactive waste. The activation energy of the catalytic decomposition decreased to approximately half of that of the thermal decomposition. Coexistence of nitrogen dioxide with chlorobenzene increased the decomposition rate of chlorobenzene. Addition of calcium hydroxide as an absorbent also increased the conversion. The conversion obtained with the simulated catalyst regenerated with oxalic acid was almost same to that obtained with the mixed powder of uranium oxide and calcium hydroxide at 225℃.
