There are several forms of obtaining hydrogen, including steam reforming of hydrocarbons, alcohols, and ethers. Some characteristics of methanol, such as processing at mild temperatures from 250 to 350oC under atmospheric pressure and production from biomass – no competition for food production – have distinguished it from other alcohols for steam reforming. The great disadvantage of this technology when applied in proton exchange membrane (PEM) fuel cells is that the process of methanol steam reforming involves not only hydrogen and carbon dioxide, but also the production of a small amount of carbon monoxide, which is sufficient to affect the functionality of the fuel cells. This work presents the characterization of the catalyst HiFUEL R120 and shows how water/methanol molar ratio in the feed stream of an integral methanol steam reforming reactor influenced the conversion and the hydrogen selectivity in relation to carbon monoxide. This made it possible to identify the best operational conditions for lowering carbon monoxide content in the reactor effluent, avoiding the use of a CO purification unit. 2019 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303260200053 https://www.redalyc.org/journal/3032/303260200053/ https://www.redalyc.org/journal/3032/303260200053/html/ https://www.redalyc.org/journal/3032/303260200053/303260200053.epub https://www.redalyc.org/journal/3032/303260200053/movil https://doi.org/10.4025/actascitechnol.v41i1.39926 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
