US7918906B2 - Compact natural gas steam reformer

The present invention is natural gas steam reforming apparatus for generating an output gas mixture of carbon dioxide and hydrogen. The apparatus is made from two enclosures. A first enclosure contains a source of water, superheated steam, and channels, located within a lower portion of the first enclosure, which contain a water-gas-shift catalyst for converting CO into CO 2 and H 2 .
