Abstract
(EN)
A co-crystallized zeolite catalyst for synthesizing pyridine bases comprises (by weight): from 25% to 45% of rare earth-ZSM5/ZSM11 co-crystallized zeolite, from 0.5% to 3.0% of TiO2, and the balance being alumina and kaolin. The catalyst can be prepared by mixing rare earth-ZSM5/ZSM11 co-crystallized zeolite, TiO2, alumina, kaolin, and water homogeneously, wherein the weight ratio of solid to water in the mixture is in the range from 0.2 to 0.5, spray shaping and then drying. The process for synthesizing pyridine bases in presence of such catalyst can be easily operated and has good pyridine bases selectivity.
(FR)
L'invention concerne un catalyseur de zéolithe cocristallisée utile pour synthétiser des bases pyridine, qui comprend (en poids): de 25% à 45% de zéolithe cocristallisée ZSM5/ZSM11 de terres rares, de 0,5% à 3,0% de TiO2, le reste étant de l'alumine et du kaolin. Ce catalyseur peut être élaboré par la mise en œuvre des étapes consistant à mélanger de manière homogène la zéolithe cocristallisée ZSM5/ZSM11 de terres rares, le TiO2, l'alumine, le kaolin et de l'eau, le rapport en poids matières solides/eau du mélange étant compris dans la plage de 0,2 à 0,5; façonner le mélange par pulvérisation et le sécher ensuite. Le procédé de synthèse de bases pyridine en présence d'un tel catalyseur peut être mis en œuvre facilement et présente une bonne sélectivité de bases pyridine.
