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™ 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.

Table 1. Refinery F, targeting maximum propylene yields, successfully used the latest ProtAgon™ 4G latest catalyst technology.

Fig.2. ProtAgon-4G provides 0.7 wt% additional propylene at Refinery F.

By subsequently upgrading to the ProtAgon™ 4G technology, the refinery was able to further boost the propylene yield by an additional 0.7wt%.
