| titleOfInvention | SAPO-11 molecular sieve, and preparation method and application thereof |
| abstract | The invention provides an SAPO-11 molecular sieve, a preparation method and an application thereof, belonging to the technical field of molecular sieve catalyst preparation. Co is doped in the SAPO-11 molecular sieve, and the Co doping can influence the coordination between silicon and aluminum in the molecular sieve, so that the property of B acid in the molecular sieve is changed, Co replaces aluminum atoms to enter an SAPO-11 framework to form an acid center, and the acid strength is enhanced; and Co doping can disperse silicon atoms in a crystal skeleton to generate new acid sites, and can increase the total acid site concentration, so that the catalytic activity of the molecular sieve catalyst is improved, and the yield of isomers is improved. |
