The new matrix systems contained in
ResidMax catalysts are derived from unique high performance
reactive aluminas developed and manufactured by Grace Davison.
Through proprietary processing, Grace Davison is able to control
alumina morphology, acidity and surface chemistry, generating
Tunable Matrix Aluminas (TMA’s).
Combination of these TMA’s with our
alumina-sol binder system generates matrix systems with pore
networks and unique surface chemistry that can be modified to
optimise the overall performance of the FCC catalyst.
ResidMax Catalysts have been shown to
give enhanced metals tolerance and bottoms upgrading versus
state-of-the-art resid cracking catalysts.
The ability to produce active aluminas
with tunable properties (e.g. morphology, acidity and surface
chemistry) is an important development in FCC catalyst matrix
design expanding our portfolio of Selective Active Matrix (SAM)
systems that are the most widely used matrix sytstems in the
European refining industry.
ResidMax catalysts can be formulated to
meet a wide range of refinery objectives through adjustment of
the hydrogen transfer characteristics of the CSX zeolite and the
intrinsic properties of the TMA matrices. Furthermore, ResidMax
catalysts are fully compatible with Grace Davison additives for
LPG olefins and gasoline sulphur reduction.
The ResidMax series of catalysts is
best suited for refiners processing residue feedstocks with very
high levels of contaminant metals.
