    摘要: One exemplary embodiment can be a process for removing one or more polynuclear aromatics from at least one reformate stream from a reforming zone. The PNAs may be removed using an adsorption zone. The adsorption zone can include first and second vessels. Generally, the process includes passing the at least a portion of an effluent of the reforming zone through the first vessel containing a first activated carbon. The adsorption zone is operated at a temperature of at least 370° C.

    摘要: 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 about 0.300 to about 1.00 gram per cubic centimeter. The catalyst has a platinum content of less than about 0.375 wt %, a tin content of about 0.1 to about 2 wt %, a potassium content of about 100 to about 600 wppm, and a cerium content of about 0.1 to about 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.
