Catalyst Services

CRI-Criterion developed the actiCAT Ex-situ Presulfurization process in the early 1990’s in order to provide refining customers with a faster and easier start-up of hydrotreating catalysts that also achieved maximum performance from the catalyst.  Criterion licensed the actiCAT technology to Porocel Industries in 2004.  Criterion continues to offer the actiCAT service from its manufacturing plant in Medicine Hat, Alberta, Canada.  Porocel offers the actiCAT service from their plants in Lafayette, Louisiana;   Rodange, Luxembourg; and Singapore.

There are 4 versions of actiCAT
1) actiCAT-HT - for all NiMo and CoMo on alumina used in hydrotreating applications. 
2) actiCAT-HC - for NiW  catalysts, generally used in hydrocracking operations. 
3) actiCAT-TG - for the CoMo on alumina catalysts used in tail gas applications. 
4) ActiCAT-PG - for CRI Kataleuna catalysts used in pygas applications. 

Criterion’s CAT-CHECKSM is a knowledge based management system for optimizing catalyst performance and utilization.  Recognizing customer needs, we developed this approach to monitor catalyst performance in the unit with minimum customer effort. Our consultants translate the data to quickly obtain an intimate knowledge of the unit and to compare this information with our extensive knowledge base built up over many years. We are better positioned to rapidly gain an understanding of what’s possible for the unit and with a goal to unlock its hidden
potential. CAT-CHECK is proving to be an overwhelming success.

ENCORE is a process developed by Criterion using patented technologies for reactivation of spent CENTINEL and CENTINEL GOLD catalysts.  ENCORE reverses both coke deactivation and deactivation due to metals agglomeration and sintering.  This process has demonstrated recovery to near fresh activity in many Type II catalysts.
