| 摘要 |
A reforming process is described comprising the steps of (a) partially oxidising a feed-gas comprising a hydrocarbon feedstock with an oxygen containing gas, (b) bringing the composition of the resulting partially oxidised gas stream towards equilibrium by passing said partially oxidised gas stream over a reforming catalyst to provide a raw synthesis gas mixture, (c) cooling said raw synthesis gas mixture and (d) separating condensed water from the raw synthesis gas mixture, characterised in that prior to the step of separating the condensed water from the raw synthesis gas mixture, part of said raw synthesis gas mixture is recycled to the partial oxidation step. The recycle of raw synthesis gas mixture to the partial oxidation step provides an energy-efficient source of hydrogen and steam that may e.g. inhibit carbon formation. |
