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.

Abstract: The invention relates to: a catalytic composition that is active in the selective catalytic reduction of nitric oxides, containing an iron-containing MFI-type zeolite and an iron-containing BEA-type zeolite, wherein the weight average particle size d50 of the MFI-type zeolite and the BEA-type zeolite is different; a method for producing an SCR catalyst; and the SCR catalyst produced in this way. The adhesion of the coating is improved in that the weight average particle sizes of the MFI-type and BEA-type zeolites are different.
