磷酸硅铝 (ＳＡＰＯｓ)能提高催化剂的活性 ,其新颖之处是硅含量较高。一种ＦＣＣ工艺包括将原料注入包括反应段的ＦＣＣ装置的提升管反应器 ,并在上述催化剂存在下 ,原料裂化生成裂化产品。催化剂主要成分为大孔沸石催化剂和少量由四面体骨架的含硅、铝和磷组成的分子筛。该分 Silicon aluminum phosphate (SAPOs) can increase the activity of the catalyst, the novelty is higher silicon content. One FCC process involves injecting a feedstock into a riser reactor of an FCC unit that includes a reaction section and cracking the feedstock to produce a cracked product in the presence of the above catalyst. The main components of the catalyst for the large-pore zeolite catalyst and a small amount of tetrahedral skeleton containing silicon, aluminum and phosphorus molecular sieve. The minute
