ProtAgon™ 4G

ProtAgon™ 4G
ProtAgon™ 4G is the latest generation of Grace’s propylene
maximization technology. Propylene yields of over 12wt%
have been achieved with this catalyst technology.
ProtAgon™ 4G is manufactured using the Grace EnhanceR™
Technology Platform, and is an extension of the ProtAgon catalyst
family, which is the market leader in the EMEA region (Fig. 1).
ProtAgon™ 4G Case Study
Refinery F switched to ProtAgon™ 4G to help them achieve the
design propylene yield of over 12.5wt% following a major unit
revamp in this hydrotreated VGO feed application.

platform in EMEA.
ProtAgon™ catalysts bring the following performance benefits to
unit operations and product quality:
• highest propylene yields
• high intrinsic cracking activity
• improved operational flexibility
• premium bottoms upgrading
• excellent attrition resistance
The enhanced propylene selectivity of ProtAgon™ 4G catalysts
can also be used to provide improved operational flexibility at
constant high propylene yields by relieving constraints in FCC
units, which are not able to handle very high propylene production
levels.
By subsequently upgrading to the ProtAgon™ 4G technology,
the refinery was able to further boost the propylene yield by an
additional 0.7wt%.
