PROCESS FOR PRODUCING SYNTHESIS GAS FROM A HYDROCARBON-CONTAINING FEEDSTOCK

摘要

In a multi-step process for producing synthesis gases containing H2, CO and CO2 from hydrocarbon-containing feedstocks (1), in which (a) the feedstocks (1) are first subjected to a primary steam reforming (6),(6'), (b) then to a partial oxidation (12) with the aid of an oxygen-containing additive (13) and (c) then to a further steam reforming (10) and (d) in which subsequently an exothermic catalytic carbon monoxide conversion (CO conversion) (7) is carried out, an optimisation should be achieved, in particular as far as the heat utilisation is concerned and the possibility of reducing the O2 consumption of known processes and of building compact plants, especially also particularly compact reactors. This is achieved by employing the waste heat of the exothermic carbon monoxide conversion for at least partial primary steam reforming.
