Stabilizing catalyst activity during catalyst regeneration |
摘要 |
This invention is directed to methods of converting oxygenates to olefin products. The methods provided include steps for protecting against deactivation of active molecular sieve catalysts during the conversion process. In particular, the invention provides for methods of regenerating coked catalyst to minimize catalyst deactivation due to contact with moisture.
