Process for the preparation of hydrogen and carbon monoxide containing gas from a gaseous carbonaceous feedstock by performing the following steps: (a) auto-thermal reforming of a gaseous feedstock thereby obtaining a first gaseous mixture of hydrogen and carbon monoxide, (b) catalytic steam reforming of the gaseous carbonaceous feedstock to obtain a second gaseous mixture of hydrogen and carbon monoxide by feeding steam and the gaseous carbonaceous feedstock through a first set of numerous microchannels provided with a steam reforming catalyst and feeding the first gaseous mixture of hydrogen and carbon monoxide through a second set of numerous microchannels, wherein the first and second set of microchannels are oriented such that the required heat for the steam reforming reaction in the first set of microchannels is provided by convective heat exchange from the second set of microchannels, thereby obtaining the hydrogen and carbon monoxide containing gas as the effluent of the second set of microchannels. |
