METHOD AND A SYSTEM FOR COMBINED HYDROGEN AND ELECTRICITY PRODUCTION USING PETROLEUM FUELS

摘要

SOFC systems are provided for producing purified carbon dioxide products, power, and compressed hydrogen products. Directing hydrocarbon fuel and steam to the SOFC system, wherein the steam-to-carbon molar ratio in the pre-reformer is in the range of about 3: 1 to about 4: 1, and the oxygen in the reformer combustion chamber is excess and is produced during the process Operating the SOFC system is a step in the process such that at least 90% of the carbon dioxide thus formed forms a purified carbon dioxide product. Alternative fueling stations equipped with SOFC systems are useful for refueling both electricity and hydrogen to alternative fuel vehicles. The steps of the method may include guiding steam and hydrocarbon fuels, operating an alternative fueling station, connecting an alternative fuel vehicle with said alternative fueling station, guiding a substantial amount of alternative fuel, and said alternative fuel vehicle. Separating.
