【 摘 要 】

The coupling conversion of C6-C8 olefins and methanol over SAPO-34 is proposed for enhancing carbon resource utilization and light olefins production. With the aid of thermogravimetric analysis (TGA), dissolution-extraction experiment and molecular dynamics simulations, the relationship between reactive “coke” and reaction pathway of methanol-to-olefin (MTO) are studied. Owing to its remarkable product shape selectivity, octene is explored to be an effective coking source for promoting ethene production.
