Review of 2015 Trends in Fluid Catalytic Cracking Patents, Part I: Catalyst Additives
This is the first article in a review of patents issued in 2015 in the area of Fluid Catalytic Cracking (FCC). The summary below covers five patents relating to FCC catalyst additives. These include: two related to gasoline sulfur reduction catalysts; two related to metals deactivators/traps; and a ZSM-5 additive patent. Review of this collection of patents illustrates a somewhat subdued activity in additive research activity for the FCC, at least that devoted to patentable activities. To be fair, there are almost double the number of “catalyst” related patents, and some of these are directed to olefin production, which would boost the number in the olefin/octane area. These will be summarized next month. For the sulfur reduction and metals trapping areas, time will tell whether there is a resurgence in these areas.
