Abstract:
A process is presented for increasing the conversion efficiency of oxygenates to olefins. The conversion of oxygenates recycles unconverted oxygenates and oxygenate by-products to a second reactor unit. The present of oxygenate by-products decreases the efficiency of the methanol to olefins reaction, and passing recycled oxygenates to a second reactor unit maintains the methanol to olefins conversion efficiency while converting the by-products in a secondary zone.
