One exemplary embodiment can be a process for facilitating a transfer of a metal catalyst component from at least one donor particle to at least one recipient particle in a catalytic naphtha reforming unit. The process can include transferring an effective amount of the metal catalyst component from the at least one donor particle to the at least one recipient particle under conditions to effect such transfer to improve a conversion of a hydrocarbon feed.

One exemplary embodiment can be a process for facilitating adding a promoter metal to at least one catalyst particle in situ in a catalytic naphtha reforming unit. The process can include introducing a compound comprising the promoter metal to the catalyst naphtha reforming unit and adding an effective amount of the promoter metal from the compound comprising the promoter metal to the catalyst particle under conditions to effect such addition and improve a conversion of a hydrocarbon feed.

One exemplary embodiment can be a process for lowering an amount of carbon monoxide in a stream rich in hydrogen. The process can include passing the stream rich in hydrogen through a carbon monoxide removal zone to produce a product stream having no more than about 10 vppm carbon monoxide and communicating the product stream to a reduction zone receiving a catalyst comprising unreduced metal species.

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.
摘要:
A process is presented for the increasing the yields of aromatics from reforming a hydrocarbon feedstream. The process includes splitting a naphtha feedstream into a light hydrocarbon stream, and a heavier stream having a relatively rich concentration of naphthenes. The heavy stream is reformed to convert the naphthenes to aromatics and the resulting product stream is further reformed with the light hydrocarbon stream to increase the aromatics yields. The process includes passing a catalyst stream in a counter-current flow relative to the hydrocarbon process stream.
