<p>A process for producing high purity hydrogen is disclosed. Specifically, the process includes (1) partially oxidizing either a refinery offgas feedstock or a gaseous hydrocarbonaceous feedstock, which contains a major component which includes at least one C1-C3 hydrocarbon and which has an average molecular weight of up to about 30, to produce a synthesis gas mixture of carbon monoxide and hydrogen, (2) reacting the synthesis gas mixture with steam to convert the carbon monoxide into a raw gas mixture which primarily includes carbon dioxide and hydrogen, and (3) subjecting the raw gas mixture to pressure swing adsorption to purify the raw gas mixture, thereby producing high purity hydrogen and a reject gas mixture of impurities. <IMAGE></p> |
