Aromatization fluidized bed catalyst and preparation method thereof

The invention discloses an aromatization fluidized bed catalyst and a preparation method thereof. The aromatization fluidized bed catalyst comprises the following components: a) 0.5%-20% of at least one selected from first metal element oxides; b) 0.5%-15% of an oxide of at least one selected from P, B, Si, a second metal element, a rare earth element or a noble metal element; c) 30%-60% of a molecular sieve; d) 10%-30% of a component selected from a binder; e) 20%-65% of modified kaolin; wherein the specific surface area of the modified kaolin is 25-100m < 2 >/g. The aromatization fluidized bed catalyst has the advantages of low wear index and high aromatic hydrocarbon yield. 本发明公开了一种芳构化流化床催化剂及其制备方法。本发明芳构化流化床催化剂，包括以下组分：a)0.5％～20％选自第一金属元素氧化物中的至少一种；b)0.5％～15％选自P、B、Si、第二金属元素、稀土元素或贵金属元素中的至少一种的氧化物；c)30％～60％选自分子筛；d)10％～30％选自粘结剂组分；e)20％～65％选自改性高岭土；其中，所述改性高岭土的比表面积为25～100m2/g。该芳构化流化床催化剂具有磨损指数低与芳烃收率高的优点。
