1. A process for producing molecular hydrogen (H2), carbon monoxide and a carbon-containing product, the process comprising the following steps:
(a) providing molecular hydrogen (H2) and molecular oxygen (O2),
(b) heating a bed of carbon-containing material to a temperature of >800° C. by reacting the molecular hydrogen (H2) with the molecular oxygen (O2),
wherein steps (a) and (b) proceed in the same reaction apparatus,
(c) drawing off the synthesis gas formed, containing molecular hydrogen (H2) and carbon monoxide,
(d) ending the provision of molecular hydrogen (H2) and molecular oxygen (O2) no later than upon reaching a temperature of the bed of carbon-containing material of 1800° C.,
(e) providing a gaseous hydrocarbon stream and decomposing the hydrocarbons in the presence of the bed of carbon-containing material to give carbon and molecular hydrogen (H2), the temperature of the bed of carbon-containing material decreasing in the process,
(f) drawing off the molecular hydrogen (H2),
(g) ending the provision of a gaseous hydrocarbon stream no later than upon reaching a temperature of the bed of carbon-containing material of ≤900° C., and
(h) withdrawing at least a portion of the carbon-containing material of the bed, wherein the carbon-containing material includes a deposit comprising the carbon-containing product.
