| titleOfInvention | Small-grain SSZ-13 molecular sieve containing hierarchical pores and synthesis method thereof |
| abstract | The invention discloses a small crystal grain SSZ-13 molecular sieve containing hierarchical pores and a synthesis method thereof, wherein the method comprises the following steps: (1) mixing an aluminum source, a silicon source, a structure directing agent, an alkali metal hydroxide and water according to a certain proportion, and fully stirring to obtain slurry; (2) adding a certain amount of chloride auxiliary agent and seed crystal into the slurry obtained in the step (1), and fully stirring to obtain a material to be crystallized; (3) and (3) transferring the material to be crystallized in the step (2) into a crystallization kettle for crystallization for 4-48 h, and then washing, filtering, drying and roasting the slurry after crystallization is completed to obtain the SSZ-13 molecular sieve. The synthesis method has the advantages of short synthesis time, high crystallinity of the SSZ-13 molecular sieve, small crystal grain, unique hierarchical pore structure and specific surface area larger than that of the molecular sieve>700m 2 Has good hydrothermal stability and catalytic activity. |
