Purge gas streams to stagnant zones within oxygenate-to-olefin reactor |
摘要 |
The present invention comprises a process for conversion of oxygenates to olefins comprising contacting within a reactor the oxygenates with a catalyst to produce light olefins and wherein the reactor comprises at least two zones, a first zone wherein gas circulates at a faster rate than a second zone wherein a gas circulates at a slower rate; and inserting a quantity of inert gas into the second zone to increase circulation of any materials located in said second zone. The invention prevents accumulation of undesirable by-products within stagnant zones within the reactor and reduces the amount of coke deposited on catalyst or on surfaces within these zones.
