  1. PROX

    PROX is an acronym for PReferential OXidation, and refers to the preferential oxidation of a gas on a catalyst. The catalyst preferentially oxidises carbon monoxide using a heterogeneous catalyst placed upon a ceramic support. Catalysts include metals such as platinum, platinum/iron, platinum/ruthenium, gold nanoparticles as well as novel copper oxide/ceramic conglomerate catalysts. This reaction is a considerable subject area of research for fuel cell design. From the reaction of carbon monoxide with steam, carbon dioxide is evolved. The presence of CO impedes the reaction of H2/O2 and reduces the fuel cell efficiency by the adsorption of CO onto the platinum anode. The PROX process allows for the reaction of CO with oxygen, reducing CO concentration from approximately 0.5-1.5% in the feed gas to less than 10 ppm. However, a selectivity of 100% is impossible. The selectivity, S, is used in reference to the auxiliary reaction, which is the oxidation of hydrogen. The disadvantage of this technology is its very strong exothermic nature, coupled with a very narrow optimal operation temperature window, and is best operated between 353 and 450 kelvins, yielding a steam loss of around one percent. Effective cooling is therefore required. In order to minimise steam generation, excessive dilution with nitrogen is used. Additionally the reaction is interrupted with an intermediary cooler before proceeding to a second stage.
