  • Patent number: 8758599
    Abstract: One exemplary embodiment can be a catalyst for catalytic reforming of naphtha. The catalyst can have a noble metal including one or more of platinum, palladium, rhodium, ruthenium, osmium, and iridium, a lanthanide-series metal including one or more elements of atomic numbers 57-71 of the periodic table, and a support. Generally, an average bulk density of the catalyst is about 0.300-about 0.620 gram per cubic centimeter, and an atomic ratio of the lanthanide-series metal:noble metal is less than about 1.3:1. Moreover, the lanthanide-series metal can be distributed at a concentration of the lanthanide-series metal in a 100 micron surface layer of the catalyst less than about two times a concentration of the lanthanide-series metal at a central core of the catalyst.
