Patent ID: 8758599

Claim:
A catalyst for catalytic reforming of naphtha, comprising: A) a noble metal comprising one or more of platinum, palladium, rhodium, ruthenium, osmium, and iridium; B) a lanthanide-series metal comprising one or more elements of atomic numbers 57-71 of the periodic table; and C) a support; wherein an average bulk density of the catalyst is about 0.300-about 0.620 gram per cubic centimeter, an atomic ratio of the lanthanide-series metal:noble metal is less than about 1.3:1, and the lanthanide-series metal is distributed at a concentration of the lanthanide-series metal in a 100 micron surface layer of the catalyst greater than one times but less than or equal to 1.75 times a concentration of the lanthanide-series metal at a central core of the catalyst.
