Hybrid Catalyst
While
HS catalysts offer superior economic performance to customers, process
constraints in some plants limit the use of HS catalysts. Therefore,
CRI scientists have embarked upon an ambitious R&D program designed
to unite the best features of both the HA and HS catalysts into a
single catalyst that any EO plant in the world could operate. The
result? S-877 & S-891. These catalysts feature much higher
selectivity than HA catalysts, while retaining better long-term activity
and stability than HS catalysts. Although only recently introduced
into the marketplace, there has been wide acceptance of these catalysts,
which now number dozens of commercial charges.
