摘要:
The invention relates to a process for the production of a synthesis gas SG 1. Process for the production of a synthesis gas SG that has an H2/CO ratio of between 1.9 and 2.3 starting from a carbon-containing material that is relatively low in hydrogen, water and electrical energy, in which: Electrolysis of the water is carried out to produce, on the one hand, oxygen, and, on the other hand, hydrogen, A CF current that comprises at least the majority of the carbon contained in the carbon-containing material CF is subjected to a partial oxidation POX with essentially pure oxygen produced by electrolysis, At least a portion of the hydrogen that is produced by electrolysis is added to the CF current upstream and/or downstream from the partial oxidation POX, in such an amount that the H2/CO ratio of the final synthesis gas SG is between 1.9 and 2.3, the carbon-containing material being dried upstream from the POX so that the O2/H2 molar ratio of the POX-supplied oxygen to the added hydrogen is between 0.45 and 0.55.
