具有高辛烷值桶的催化裂化助催化剂
摘要：
一种催化裂化助催化剂是以SiO2、Al2O3或SiO2·Al2O3之一为载体，负载10～40重％含稀土的五元环结构高硅沸石构成的。该高硅沸石具有ZSM-5沸石族的X光衍射谱图，但孔径较ZSM-5更为狭窄，其无水化学表达式为XRE2O3、YNa2O·Al2O3·ZSiO2，其中X＝0.01～0.30、Y＝0.4～0.6、Z＝20～100。该助催化剂具有较常规ZSM-5或REZSM-5助催化剂为高的产物汽油辛烷值桶和较低的生焦率。
摘要（英）：

This promoter for catalysis and cracking is prepared up from one of SiO2, Al2O3 or SiO2.Al2O3 that acts as carrier and high-silicon zeolite (10-40 wt.%) with five-membered ring structure containing rare-earth. The high-silicon zeolite has same X-ray diffraction spectrum as ZSM-5 zeolite family, but narrower aperture. Its anhydrous chemical expression is XRE2O3, YNa2O.Al2O3.ZSiO2, where X=0.01-0.30, Y=0.4-0.6 and Z=20-100. This promoter has higher octane number for its product (gasoline) and lower coking rate as compared with conventional ZSM-5 or REZSM-5 promoters.
