水热稳定的微孔分子筛催化剂及其制备方法

Hydrothermally stable microporous molecular sieve catalyst and preparation method thereof

Abstract

Disclosed are a hydrothermally stable porous molecular sieve catalyst and a preparation method thereof. The catalyst consists of a product obtained by the evaporation of water from a raw material mixture comprising a molecular sieve having a framework of Si-OH-Al-, a water- insoluble metal salt and a phosphate compound. The catalyst maintains its physical and chemical stabilities even in an atmosphere of high temperature and humidity. Accordingly, the catalyst shows excellent catalytic activity even when it is used in a severe process environment of high temperature and humidity in heterogeneous catalytic reactions, such as various oxidation/reduction reactions, including catalytic cracking reactions, isomerization reactions, alkylation reactions and esterification reactions.
本发明公开了一种水热稳定的多孔分子筛催化剂及其制备方法。所述催化剂由从包含具有-Si-OH-Al-骨架的分子筛、水不溶性金属盐和磷酸盐化合物的原料混合物中蒸发水得到的产物构成。所述催化剂即便在高温高湿气氛中也能保持其物理和化学稳定性。因此,所述催化剂即便用于多相催化反应,例如各种氧化/还原反应,包括催化裂解反应、异构化反应、烷基化反应和酯化反应中的高温高湿的恶劣恶劣的工艺环境中,也能显示出优良的催化活性。
