  • Steam reforming catalyst for hydrocarbon-containing gas, apparatus for producing hydrogen, and method for producing hydrogen
    Patent number: 10259709
    Abstract: Problem to be Solved A catalyst for obtaining hydrogen gas by steam reforming of a hydrocarbon-containing gas in the presence of steam including active metals supported on an ?-alumina carrier. The active metals include 0.1 to 0.3 parts by weight of rhodium (Rh) based on the content of the metal, relative to 100 parts by weight of the ?-alumina carrier, and 0.01 to 0.3 parts by weight of platinum (Pt) based on the content of the metal, relative to 100 parts by weight of the ?-alumina carrier. The ?-alumina carrier is modified with a promoter including 1 to 10 parts by weight of cerium (Ce) based on the content of the metal, relative to 100 parts by weight of the ?-alumina carrier.
