As refiners enter the reformulated gasoline era, it is clear that the FCCU will play a major role as a producer of iso-olefins to be used as feedstocks for oxygenate production. Engelhard has developed and commercialized a new family of IsoPlus[trademark] FCC catalysts designed to maximize yields of isobutylene and isoamylenes. The IsoPlus 1000 series is designed to aid refiners currently operating MTBE and/or TAME units with spare capacity by providing isobutylene and isoamylene yield increases of up to 50%, compared to previously available USY based catalysts, while fitting into typical units operating constraints. The IsoPlus 2000 series is designed to offer refiners an option for the future when even higher iso-olefin yields will be required. IsoPlus 2000 series catalysts can increase iso-olefin yields by 100% or more when used in combination with unit hardware upgrades to ease constraints typical of current operations. Some significant developments have occurred in the past year to advance this new catalytic technology closer to widespread commercial practice. Laboratory studies at Engelhard have confirmed the selectivity benefits of the IsoPlus catalysts on a wide variety of commercial FCC feedstocks, and tests conducted by outside laboratories have also supported these results. An economic evaluation of the commercial potential for these catalysts conducted by a major independent contractor showed encouraging results. Both IsoPlus 1000 and IsoPlus 2000 have been manufactured commercially and used successfully in commercial FCC units, with preliminary resulted confirming expectations. Each of these developments is discussed in this paper.
