Process and apparatus for producing one or more reaction products

It is a process for producing one or more reaction products, in which a first methane-rich feed stream (b) a partial oxidation process and / or an autothermal reforming process (1) and a second methane-rich feed stream (s) is subjected to a steam reforming process (3), and wherein the means of the partial oxidation process and / or the autothermal reforming process (1), a first synthesis gas-containing effluent from a second synthesis gas-containing effluent (g) is formed (d) and by means of the steam reforming process (3), from synthesis gas of the first effluent (d) and is the second effluent (g) forming a synthesis gas collection stream (h) and the fluid of the synthesis gas collection stream (h) in a synthesis feed current (i) to obtain a carbon dioxide and the or containing the reaction products Syntheseabstroms (k) subjected to a constituent reaction proposed. From the fluid Syntheseabstroms (k) at least one carbon dioxide-rich recycle stream first (p) is formed, and the fluid of the first recycle stream (p) is subjected to the steam reforming process (3). A corresponding system (100) is also subject of the present invention.
