Porocel Introduces Technology that Restores Spent Catalysts to Near Fresh


(Houston, March 19, 2015) ---Porocel International, LLC, today announced the commercialization of its patented ExcelSM rejuvenation process for restoring spent hydrotreating catalysts to near fresh activity.
According to Peter Douvry, Porocel’s business development manager, the ExcelSM rejuvenation process applies proprietary additives to regenerated catalyst to re-disperse active metals. “It’s a two-step process,” said Douvry, “beginning with thermal regeneration to remove carbon and sulfur followed by our proprietary chemical treatment which restores or stabilizes both Type I and Type II active sites. With this process, refiners now have access to high activity catalysts with more favorable economics than using fresh.”

Pilot plant studies conducted by Porocel demonstrated catalyst activity was consistently restored to more than 90% of original activity, making the catalysts suitable for operations processing everything from naphtha to heavy gas oil. The ExcelSM process is applicable to Porocel regenerated catalysts or the refiner’s catalysts. High quality, uncontaminated spent catalysts are used with the process to help meet stringent physical and chemical properties.

Refiners in the U.S. and Europe have confirmed ExcelSM rejuvenation’s performance gains through independent testing. Multiple start-ups using ExcelSM technology are slated for later this year.
The ExcelSM rejuvenation process is available worldwide through Porocel’s facilities in North America, Europe and Asia.
