| titleOfInvention | Preparation method of micro-mesoporous ZSM-5 molecular sieve |
| abstract | The invention discloses a preparation method of a micro-mesoporous ZSM-5 molecular sieve, which is synthesized by taking attapulgite pretreated by alkali acid as a silicon source, ammonia water as a template agent, sodium hydroxide as a post-treatment pore-forming agent and aluminum sulfate octadecahydrate as a supplementary aluminum source by a hydrothermal crystallization method. The preparation method of the micro-mesoporous ZSM-5 molecular sieve can synthesize the ZSM-5 molecular sieve with uniform crystal form, regular shape, uniform pore size distribution and large specific surface area and pore volume; the method has the advantages of simple operation, cheap and easily-obtained raw materials, low economic cost and high synthesis efficiency; mild condition, no toxicity and environmental protection. |
