One embodiment is 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, an alkali or alkaline-earth metal, a lanthanide-series metal, and a support. Generally, an average bulk density of the catalyst is 0.300 to 1.00 gram per cubic centimeter. The catalyst has a platinum content of less than 0.375 wt%, a tin content of 0.1 to 2 wt%, a potassium content of 100 to 600 wppm, and a cerium content of 0.1 to 1 wt%. 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 two times a concentration of the lanthanide-series metal at a central core of the catalyst.
