| 1. A process for producing synthesis gas using at least a first and a second steam reforming reactor each comprising at least one reaction stage enabling the circulation of a reaction mixture and at least one heat supply stage enabling the circulation of a heat transfer fluid, the process comprising the following steps: a) mixing a hydrocarbon feedstock gas and steam thereby forming the reaction mixture,
b) simultaneously supplying the reaction stages of the first and second steam reforming reactors with the reaction mixture obtained in step a),
c) producing combustion flue gases within the steam reforming reactors, wherein the combustion flue gases are used as heat transfer fluid,
d) cooling the combustion flue gases to a temperature below 1000° C.,
e) introducing the combustion flue gases from step d) into the heat supply stage of the first steam reforming reactor,
f) recovering the combustion flue gases at the outlet of the first steam reforming reactor and introducing them into the heat supply stage of the second steam reforming reactor, and
g) recovering synthesis gas at the outlet of the first and second steam reforming reactors.
