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.
