System and process for synthesis gas production

A process of reforming a first feed stream comprising a hydrocarbon gas and steam in a chemical reactor, said process comprising the steps of:

• a) electrically heating catalyst material within a reformer tube of said chemical reactor by means of an electrically driven heat source powdered by an electrical power source as sole heat source,
• b) inletting said first feed stream into a first inlet into a first reforming reaction zone of said reformer tube,
• c) carrying out reforming reaction of said first feed stream within the first reforming reaction zone,
• d) inletting a second feed stream into a feed conduit, wherein said feed conduit is configured so that said second feed stream is only in contact with catalyst material in a second reforming reaction zone,
• e) conducting said second feed stream in heat exchange contact with catalyst material housed within said reformer tube, and inletting said second feed stream into said second reforming reaction zone into said reformer tube, and
• f) carrying out reforming reaction of said first feed stream and said second feed stream within said second reforming reaction zone,
• wherein said second reforming reaction zone is positioned downstream of said first reforming reaction zone, where said second feed stream comprises at least 50 dry mole % CO2, wherein said second feed stream is heated prior to introduction thereof into the second reforming reaction zone of said reformer tube,
• wherein said electrically driven heat source comprises electrically conductive material housed within said reformer tube and said electrical power source connected to said electrically conductive material, in order to allow an electrical current to run through said electrically conductive material during operation of said chemical reactor.
