Katalytisk omdannelse av oksygenater til olefiner |
摘要 |
A method for converting oxygenates to light olefins. The method comprises contacting, in a reactor, a feedstock comprising oxygenates with a molecular sieve catalyst under conditions effective to convert the feedstock to a product including light olefins and by-products, the contacting causing carbonaceous deposits to form on at least a portion of the molecular sieve catalyst producing deactivated catalyst; removing a portion of the deactivated catalyst from the reactor; regenerating the portion of the deactivated catalyst under conditions effective to remove at least a portion of the carbonaceous deposits from the deactivated catalyst to form an at least partially regenerated catalyst; exposing at least a portion of the at least partially regenerated catalyst to at least a portion of the by-products to selectivate the portion of the at least partially regenerated catalyst to form light olefins; and contacting the selectivated portion of the at least partially regenerated catalyst with the feedstock to form the product. |
