Abstract

Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

Claims7

Dependent claims

Apparatus for the production of syngas, comprising:

a first reactor configured to exothermically react hydrocarbon-containing fuel with an oxidant gas including molecular oxygen to produce an exothermically-generated syngas product;
a first conduit configured to remove an effluent stream of the exothermically-generated syngas product from the first reactor;
a combining element configured to combine reactive diluent fluid with the effluent stream to produce a reactive mixture;
a second reactor configured to react components of the mixture to produce a reacted syngas product;
a second conduit configured to feed a stream of reacted syngas product from the second reactor to a heat exchange reformer;
and the heat exchange reformer configured to endothermically reform hydrocarbon-containing fuel gas with steam over a catalyst to produce a heat exchange-reformed syngas product, wherein the heat exchange reformer uses heat generated in the first reactor to drive at least a portion of the reforming.
