一种合成吡啶碱的共结晶沸石催化剂及其制备方法
摘要：
一种合成吡啶碱的共结晶沸石催化剂及其制备方法，该催化剂含有25-45重％稀土-ZSM5/ZSM11共结晶沸石，0.5-3.0重％TiO2，其余为三氧化铝和高岭土；将稀土-ZSM5/ZSM11，TiO2，三氧化铝，高岭土和水混合均匀，混合物中固体/水重量比＝0.2-0.5，喷雾成型和干燥，制得本发明催化剂；本发明具有可供工业操作，工艺比较简单，吡啶碱收率高等优点。
摘要（英）：

The invention relates to a pyridine base-synthesized cocrystallized zeolite catalyst and a preparation method thereof. The catalyst contains 25 to 45 by weight percent of rare earth-ZSM5/ZSM11 cocrystallized zeolite, 0.5 to 3.0 by weight percent of TiO2 and the balance of aluminium trioxide and kaolin; the rare earth-ZSM5/ZSM11, the TiO2, the aluminium trioxide, the kaolin and water are uniformlymixed, the weight ratio of solid to water in the mixture is equal to 0.2 to 0.5, and after spraying and drying, the catalyst is prepared. The invention has the advantages of industrial operability, simple technique, high pyridine base yield and the like.
