Abstract

The invention discloses a catalyst as well as a preparation method and an application thereof. The catalyst is characterized in that an anionic surfactant used as a template agent, a Keggin structural aluminum isopolyacid cation hybrid material prepared from an aluminum source is adopted, Keggin structural polyacid anions are introduced in the preparation process by adopting an impregnation method or an ion exchange method, washing and drying are carried out to prepare the catalyst. The catalyst comprises all components in parts by weight: 2-50 parts of Keggin structural aluminum isopolyacid cations, 2-20 parts of anionic surfactants and 96-30 parts of Keggin structural polyacid anions. The catalyst is high in oxidative desulfurization catalytic activity and high in recycling usability; therefore, the oxidative desulfurization catalyst is high in performance. The preparation method of the catalyst is simple, easy to operate and low in preparation cost.

Description

Technical field [0001] The present invention involves a catalyst and its preparation methods and its application, especially a catalyst and its preparation method and application of organic sulfur removal with the KEGGIN structure. Background technique [0002] Vehicle gasoline and diesel will gradually implement the national V standard, and the sulfur content of vehicle gasoline and diesel should be controlled below 10 μg / g.The advantages of oxide desulfurization gradually attracted people's attention with the advantages of high desulfurization rate and mild response conditions.Misidic acid (HPA) as a solid acid catalyst is widely used in various reaction systems of acid catalysis and oxidation and restoration catalysis with its excellent catalytic performance.Among them, keraggin structured aluminum ions [ALO 4 AL 12 (OH) 24 (H 2 O) 12 ] 7+ (AL 13 ) It has a unique molecular structure and nanomolecular size. It is of great significance for the research of catalytic chemistry, n...
