Abstract

A process for producing olefins comprising: PA0 (a) contacting hydrogen and at least one carbon oxide in a first reaction zone at conditions effective to chemically react the hydrogen and carbon oxide and produce at least one product, e.g., methanol, in the effluent of the first reaction zone; PA0 (b) contacting the effluent containing the product in a second reaction zone at conditions effective to chemically react the product and produce olefins in the effluent of the second reaction zone; PA0 (c) recovering an olefin-enriched product from the effluent of the second reaction zone; and PA0 (d) subjecting at least one of hydrogen and at least one carbon oxide from the effluent of the second reaction zone to step (a).
