Electron Microprobe Analysis of ResidUltra Ecat
� Microprobe analysis show vanadium to migrate to regions of high RE2O3.
� ResidUltra employs a RE oxide-based vanadium trap. RE oxides do not form stable compounds with silica and sulfate and thus remain available as a vanadium trap.
� ResidUltra is an integral catalyst. It is effective even in units with low vanadium mobility.
ResidUltra contain commercially proven, RE2O3-based vanadium traps.

REpLaCeR, RE free catalysts
� Several RE free catalysts were available in the 1990’s, with a primary focus on increasing gasoline octane
� Introduced the first of Grace’s new REpLaCeR™ family of RE-free catalysts called REACTOR™ , which uses new Z-22 technology, early in 2011.
� REduceR™ is the recent addition to REpLaCeR™ series of RE free catalysts, designed for resid applications.
� REBEL™ is built upon Grace Davison’s high matrix catalyst technology and incorporates the new rare-earth free Z-21 zeolite.

Zeolite Stabilization summary
� Rare Earth Impact on Zeolite
– Prevents dealumination
– Stabilizes the structure
� Rare earth controls zeolite
– Activity
– Selectivity
– Hydrogen transfer
� Prevents metals deactivation
– Very effective vanadium trap
� Alternate methods are used to stabilize the zeolites in Grace’s RE-free catalyst
– Proprietary stabilizing compounds
– Unique manufacturing processes
� Alternative materials provide activity and stability similar to RE containing catalysts
– Similar UCS as RE containing zeolites
– Truly RE-free, without stabilization, would yield a very low UCS and activity

REMEDY™ Commercial Performance – Final Remark
�The performance of REMEDY™ was a successful
– Similar Conversion levels at the same catalyst addition rate
– Low Dry Gas and Slurry Yield
– High Gasoline Selectivity at similar Octane
– Coke Selectivity was maintained– Gasoline Sulfur reduction maintained– No increase in Flue Gas Opacity
�UCS is down from 24.29Å to 24.27Å but confirms the stabilization of zeolite even without rare earth

Conclusions of REDUCER™ Commercial Performance
� Rare earth was reduced from 3.1 to 2.2 wt.% (nearly 0.2m$/annum saving in RES
for refinery CAD @1MTD)
� Despite high Ni+V, the high performance was maintained and even improved
� Base on the yield trends at 50%, refiner increased the concentration to 70% RE free catalyst
� REDUCER™ has been successfully rolled out in EMEA region(18 resid applications)
