AM-93-17 ISO-OLEFINS FOR OXYGENATE PRODUCTION USING ISOPLUSTM

Description:

As refiners enter the reformulated gasoline era, it is clear that the FCCU will play a major role as a producer of isoolefins to be used as feedstocks for oxygenate production. Engelhard has developed and commercialized a new family of ISOPIUSTM FCC catalysts designed to maximize yields of isobutylene and isoamylenes (Ref. 1). 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 unit 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.
