Abstract

Methods and devices are provided for producing syngas with an adjustable molar CO/H2 ratio. Syngas can have different proportions of CO and H2 (molar CO/H2 ratio) depending on the type and composition of starting materials. To set the desired molar CO/H2 ratio, a first sub-process is combined with at least one additional sub-process selected from: a sub-process T2 by which a second syngas B is generated from the starting material, the syngas having a molar ratio (V2) of CO to H2, wherein V1≠V2; a sub-process T3 by which the hydrocarbon(s) of the hydrocarbon-containing starting material is/are split substantially into solid carbon and hydrogen; and a sub-process T4 based on the reaction equation: CO+H2O→2CO2+H2. The methods and devices are suitable for producing syngas useful as a starting material in a plurality of chemical syntheses, for example oxo, Fischer-Tropsch, or Reppe syntheses.
