CASE STUDY: DATA DRIVEN REPLICATION OF A CATALYST

Challenges

    • CATAGEN toolset was used to generate catalyst hardware aged equivalently to a bespoke customer ageing protocol, with the added benefit of a reduction in ageing time.
    • This can have a positive impact on the number of hours needed to age the catalyst and the associated cost reduction
    • However, we had to be sure that speeding up the process will not affect the quality of our services and our data.

Solution

    • The CATAGEN toolset, specifically the CATAGEN Ageing Metric, was used to quantify the bespoke customer ageing experience.
    • An equivalent CATAGEN ageing cycle was specified and executed with industry leading control and repeatability.

Results

    • The CATAGEN Ageing Metric was used to specify the ageing approach with a 25% time reduction over the customer cycle (295 hours vs 400+ hours).
    • We achieved it in a shorter timeframe than on the customer test bench, due to increased ageing temperatures and extended, uninterrupted ageing phases (up to 175 hours per phase  in this case).
    • Ageing was complete with high repeatability and accuracy on the OMEGA test vehicle, with catalyst equivalency validated on the customer test bench.
