CATALYST PRESULFURIZATION-actiCAT®

Since 1991 when CRI introduced its breakthrough ex-situ presulfurizing process, Porocel has applied the actiCAT® process to over 130 million pounds of catalyst. The advantages of this state-of-the-art presulfurizing process are significant: faster and easier startups, full catalyst activity and selectivity, and affordability.

FASTER, EASIER STARTUPS

To activate catalyst, refiners simply heat the reactor to start-of-run temperature in the presence of hydrogen. We eliminate handling of toxic sulfurizing chemicals and the need to use temporary pumping stations. Compared to in-situ sulfurizing, average time saving is 18 hours.

FULL CATALYST ACTIVITY AND SELECTIVITY

actiCAT® proves robust in commercial startups where process upsets and channeling are common (situations which can compromise final catalyst activity and selectivity). A large number of commercial catalysts have been tested and qualified for actiCAT® processing, and actiCAT® catalyst have been used in a wide range of applications including nickel selective hydrogenation catalyst and pygas hydrotreating catalysts.

Porocel operates three actiCAT® manufacturing facilities in Louisiana, Luxembourg and Singapore.
