Energy transfer phenomena between reactant and fluent gases in PACT (Plasma Assisted Catalytic Technology) chemical reactor

Summary form only given. New chemical reactor named "PACT" is proposed, whose concept is based on the synergic effect of Plasma and Catalyst. Non-equilibrium plasma can be formed between electrodes with coated catalytic material, including photo-catalytic material like TiO/sub 2/, at room temperature and one atmosphere. We used "Tube Type PACT" based on the above concept, whose plasma may be a Silent Discharge Plasma because a glass layer exists between the electrodes. Applied electrical conditions are as follows; wave form (Sine wave), voltage (>5 kV/sub ac/), frequency (0.01/spl sim/10 kHz). Some chemical reactions like the decompositions of NO/sub x/ and CO/sub 2/ and the reforming of CH/sub 4/ were carried out. Test conditions were checked and monitored with GC-MS, NO/sub x/ meter and CCD analysis system. We found some tendencies related to the synergic effect between plasma and catalyst, and the energy transfer phenomena between reactant and flowing gases, especially in the case of CH/sub 4/ in Ar.
