METHOD AND SYSTEM FOR PRODUCING ONE OR MORE OLEFINS

Disclosed is a method for producing olefins having a carbon number of two to eight, in which carbon dioxide and hydrogen are fed to a hydrogenation step, and, wherein portions of carbon dioxide and hydrogen are then converted with one another on a bifunctional catalyst via an oxygenate as an intermediate into the one or more olefins. It is provided that the hydrogen fed to the hydrogenation step is provided by a reforming step, in which methane and water are converted into hydrogen, carbon monoxide, and carbon dioxide, and that the carbon dioxide that is fed to the hydrogenation step is provided in part using the reforming step and in part independently of the reforming step. Providing the portions of hydrogen and carbon dioxide comprises providing, using the reforming step, a gas mixture containing hydrogen, carbon monoxide and carbon dioxide and feeding at least a portion of the gas mixture to the hydrogenation step without separating hydrogen, carbon monoxide, and carbon dioxide.
