稀土钙钛矿型催化剂,为一高活性氧化催化剂。它可用于汽车排气净化、烟道气净化、烃类氧化等;在催化裂化中,可用作分子筛催化剂再生时的助燃剂。在应用中,为制成一定形状(如蜂窝状)、减少稀土用量、增加强度、简化操作工艺等, Rare earth perovskite catalyst, a high activity oxidation catalyst. It can be used for automotive exhaust gas purification, flue gas purification, hydrocarbon oxidation, etc .; in the catalytic cracking, molecular sieve catalyst can be used as a regenerant combustion improver. In applications, to make a certain shape (such as honeycomb), reduce the amount of rare earth, increase strength, simplify the operation process, etc.,
