| titleOfInvention | A kind of catalyst for preparing 1,3-butadiene and preparation method thereof |
| abstract | The invention belongs to the technical field of molecular sieve catalysts, and discloses a catalyst for preparing 1,3-butadiene and a preparation method thereof. The catalyst includes an all-silicon molecular sieve containing a BEA structure or an MFI structure and oxides of copper, zinc and yttrium supported on the all-silicon molecular sieve. The invention adopts the all-silicon molecular sieve containing BEA structure or MFI structure as the carrier, supports copper, zinc and yttrium oxides to form a three-component metal oxide composite molecular sieve catalyst. , The selectivity of 3-butadiene is high. The catalyst provided by the invention has long-term catalytic activity and continuous regeneration performance, and can be calcined and regenerated for multiple times. The catalyst has a simple preparation process, does not require acid treatment of the carrier material, requires low equipment, and has high industrial production safety; and has easily available raw materials and low production cost, which is favorable for industrialized large-scale production. |
