性质:在催化剂的流化床反应器和再生器中进行催化裂化的工艺过程。所使用的原料油和生成物见“催化裂化”。流化催化裂化使用微球(平均颗粒直径20~80μm)催化剂主要成分为硅酸铝盐,近年多用Y型沸石(SiO2/Al2O3为3~6),并且为改进催化剂性能把NaY型更换为HY型或H稀土Y型。为保持催化剂在两器间的流动,在连通管上设置喷嘴,吹入水蒸气和空气。为防止大量催化剂跑损,在两器的油气和烟气出口设有旋风分离器。两器因排列的位置不同,有并列式、高低并列式和摞在一起的正流式(或叫同轴式)。流化催化裂化是把重质油转变为轻质油最经济和普及的方法,尤其对增产汽油更为有效。而且随着催化剂性能的改进,对加工劣质原料的灵活性增加,在炼油工艺中处于最重要的地位。
