摘要
应用三元催化净化器对汽油发动机排出的废气进行无害化转化是目前最成熟的技术。它利用贵金属Pt、Pd、Rh作催化剂 ,稀土元素作助催化剂 ,同时利用发动机废气的余热 ,在净化器内同时进行氧化 -还原反应 ,使有毒气体转化成无毒的H2O、N2、CO2。
Using three-way catalys purifier to convert waste gas emitted from gasoline engine into nonpoisonous gas is the most mature technology at present.With the help of residual heat of engine emission,oxidation-reduction reaction is done in the purifier where noble metal Pt,Pd and Ph are used as catalyst and rare-earth element as anxiliary catalyst.Then the poisonous gas can be changed into nonpoisonous H2O,N2 and exhausted to the air through the muffler.`
