APPARATUS AND PROCESS FOR PRODUCING GASOLINE, OLEFINS AND AROMATICS FROM OXYGENATES

摘要

Apparatuses and processes for converting an oxygenate feedstock, such as methanol and/or dimethyl ether, in a fluidized bed containing a catalyst to hydrocarbons, such as gasoline boiling components, olefins and aromatics are provided herein.

1. A process for converting an oxygenate feedstock to olefins comprising:
a. feeding the oxygenate feedstock to a fluidized bed reactor under conditions to convert the oxygenate feedstock to a hydrocarbon mixture in a reactor effluent, wherein the fluid bed reactor comprises:
i. a catalyst; andii. at least one packing layer; b. cooling the reactor effluent comprising the hydrocarbon mixture and condensing a portion of the reactor effluent to form a mixed phase effluent; c. separating the mixed phase effluent into an aqueous liquid phase, a hydrocarbon gas phase and a hydrocarbon liquid phase; and d. separating olefins from the hydrocarbon gas phase and the hydrocarbon liquid phase.
