Abstract

Method for the preparation of synthesis gas combining electrolysis of water, tubular steam reforming and autothermal reforming of a hydrocarbon feed stock, wherein the electrolysis is operated such that all the hydrogen produced by the electrolysis is added to the re-formed gas to provide a module M=(H2- CO2)/(CO+CO2) in the withdrawn synthesis gas of between 1.9 and 2.2.

Claims (9)
