  • Publication number: 20100206771
    Abstract: For the production of hydrocarbons, in particular C2-C4 olefins, using a combined plant with a steam cracker and at least one reactor for converting an educt mixture which includes steam and at least one oxygenate, the respective intermediate product streams of the steam cracker and of the reactor are at least partly combined. To increase the yield of valuable products, a shape-selective zeolite material is used as catalyst in the reactor for oxygenate conversion and at least a part of the product streams obtained downstream of the combined plant is recirculated to the steam cracker and/or the reactor.
