Research Abstract |
A DC arc water plasma torch which is operated at atmospheric pressure by using evaporated cooling water as plasma forming gas directly. Since a large amount of H, O, and OH radicals are generated in water plasma, decomposition of hazardous materials and waste are accelerated in the treatment of water-soluble organic compounds. Since there are many water-insoluble organic wastes as well as water soluble organic waste, their decomposition was attempted in the present work. Reaction mechanism was investigated in the decomposition region with high-temperature over 10,000 K and the recombination region with 1,000 K. The intermediate products of CH and CH3 radicals were identified, and their contribution on the decomposition mechanism was clarified.
