Process and Plant for Producing One or More Hydrocarbons

A method for producing one or more hydrocarbons, comprising:

• feeding a process gas stream to a reactor arrangement, the process gas stream comprising carbon dioxide and/or carbon monoxide with hydrogen;
• converting, within the reactor arrangement, the process gas stream at least in part in a first reaction step into one or more oxygenates, which pass into the process gas stream;
• converting, within the reactor arrangement, the one or more oxygenates in the process gas stream at least in part in a second reaction step into one or more hydrocarbons, which pass into the process gas stream;
• wherein:
• the process gas stream conducted in a flow direction through the reactor arrangement;
• the reactor arrangement has one or more reactors, the one or more reactors comprising a first reaction zone and a second reaction zone, wherein the second reaction zone is arranged downstream of the first reaction zone in the flow direction;
• and
• the first reaction zone and the second reaction zone are equipped with catalysts in such a way that:
• the first and second reaction steps are catalyzed in the first reaction zone;
• the second reaction step is catalyzed in the second reaction zone;
• and
• in the second reaction zone, the first reaction step is not catalyzed or is catalyzed to a lesser extent than in the first reaction zone.
