The steady improvement over the last 25 years in the activity and stability of UOP`s platinum-rhenium (Pt-Re) semiregenerative Platforming catalysts is a direct result of UOP`s continuing commitment to meeting customer`s requirements. Many semiregenerative reforming operations took advantage of these improved catalytic offerings by raising octane and throughput. Others benefited by lowering reactor pressure to increase yields of gasoline, aromatics, and hydrogen. In 1994, UOP commercialized the R-72 semiregenerative catalyst. This catalyst offers 1 to 2 LV-% higher C{sub 5}{sup +} yield and 10 to 15% higher hydrogen yield than Pt-Re catalysts. More recently, UOP introduced a new, patented flow scheme called R-72 staged loading. The R-72 staged loading produces a synergistic effect from the use of R-72 in the lead reactors and R-56 Pt-Re catalyst in the latter reactors. The results are R-72 yields as well as the excellent activity and stability of the R-56 Pt-Re catalyst. No modifications or revamps are required to take advantage of this technology. This paper describes how R-72 staged loading works and the economic benefits that customers can derive from its use.
