CATALYST PRESULFURIZATION-actiCAT®

NEW:  actiCAT Shield® presulfurization protects catalyst from the damaging effects of olefins and aromatics found in cracked feeds. 

 

Since 1991 when CRI introduced its breakthrough ex-situ presulfurizing process, Porocel has applied the actiCAT® presulfurization process to over 300 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® presulfurization 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® presulfurized catalysts have been used in a wide range of applications including nickel selective hydrogenation catalyst and pygas hydrotreating catalysts.

 

AFFORDABILITY

actiCAT® presulfurization's convenience and quick startup time makes cost justification a snap compared to slower in-situ sulfiding.  At a fraction of the cost of fully sulfided catalyst,  actiCAT®  presulfurization is the clear economic favorite for the majority of scenarios and applications.


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