Development of Cold Plasma-Catalytic Reactor for Exhaust Purification and Experimental Research

研制了用于尾气净化的低温等离子体催化反应器,该反应器由介质阻挡放电型低温等离子发生器和金属蜂窝载体催化剂组成.采用模拟配气的实验结果表明:低温等离子体催化反应器能明显改善在低温状态下对丙稀和一氧化氮的净化效果,在高温状态主要表现为催化剂的反应活性·

Cold plasma-catalytic reactor for exhaust purification was developed, where the reactor was consisted by two parts including dielectric barrier discharge system and metal honeycomb substrate catalyst. The purification efficiency of the reactor was evaluated on test bench using mixed gas which is able to simulate vehicle emission gases.The test results show that, compared with catalyst, the cold plasma-catalytic reactor can improve conversion efficiencies of propene and nitric oxide under low gas temperature, while it is not able to promote purification efficiency under high gas temperature.
