Claims
1. Method for the preparation of synthesis gas comprising the steps of (a) ing a separate hydrogen containing stream and a separate oxygen containing stream by electrolysis of water and/or steam; 10 (b) providing a hydrocarbon feed stock; (c1) steam ing a part of the arbon feed stock from step (b) and/or a second hydrocarbon feedstock, both the part of the first hydrocarbon feed stock and/or the 15 second feedstock being in indirect heat transfer onship with part or all of an autothermal reformed gas leaving step (d) and mixing the heat exchange steam reformed gas stream with the autothermal reformed gas downstream step (d); or (c2) heat exchange steam reforming a part or all of the hydrocarbon feed stock from step (b) in indirect heat transfer relationship with part or all of an autothermal reformed gas leaving step (d) to a heat exchange steam re- 25 formed gas and introducing the heat exchanged steam reformed gas into an autothermal reformer in step (d) to obtain the autothermal reformed gas for use in step (c2); (d) providing in an autothermal reformer the autothermal 30 reformed gas for use in step (c1) or step (c2) by ermal reforming a part of the hydrocarbon feed stock from step (b) or at least a part of the heat exchange steam reformed gas from step (c2) with at least a part of the separate oxygen containing stream from step (a); (e) ucing at least part of the separate hydrogen con- 5 taining stream from step (a) into the mixed heat exchange reformed gas and autothermal reformed gas downstream step (c1) or into the autothermal reformed gas downstream step (d) to obtain a synthesis gas comprising en, carbon monoxide and carbon dioxide and having a module M, where 10 M=(H2-CO2)/(CO+CO2), of between 1.9 and 2.2; and (f) withdrawing the sis gas.
