Description

A method for increasing light olefin yield during conversion of oxygenates to olefins comprising: contacting an oxygenate feed in a first reactor with a non-zeolitic molecular sieve catalyst under first conditions effective to produce a first product comprising light olefins and a heavy hydrocarbon fraction; separating said light olefins from said heavy hydrocarbon fraction; feeding said heavy hydrocarbon fraction to a second reactor, and subjecting said heavy hydrocarbon fraction in said second reactor to second conditions effective to convert at least a portion of said heavy hydrocarbons to light olefins.

L'invention porte sur un procédé d'augmentation du rendement d'oléfines légères au cours de la conversion de composés oxygénés en oléfines. Ce procédé consiste à mettre en contact une charge de composés oxygénés dans un premier réacteur avec un catalyseur de sève moléculaire non zéolitique dans des premières conditions efficaces de façon à obtenir un premier produit comprenant des oléfines légères et une fraction d'hydrocarbures lourds; à séparer ces oléfines légères de la fraction d'hydrocarbures lourds; à charger la fraction d'hydrocarbures lourds dans un second réacteur, et à soumettre cette fraction à des secondes conditions efficaces de façon à convertir au moins une partie de ces hydrocarbures lourds en oléfines légères.
