Catalysts
Optimizing catalyst particle size distribution to maximize its lifetime while retaining activity.
Malvern’s applications knowledge in the areas of heterogeneous catalysts and catalyst preparation leads to extended lifetime and cost savings in production.
An optimal size range exists for a catalyst and catalyst support that will maximize its lifetime while retaining its activity. The accuracy and precision of Malvern’s characterization equipment allow that range to be more than defined – it is possible to push to the limits allowing catalyst lifetimes to be extended. Product optimization and characterization application areas include:
- FCC catalysts where a prediction of the attrition rate and thus the lifetime can be made from the slope of the pressure-size titration in a dry analysis.
- Supported metal and alloy catalysts.
- ‘Black’ metal catalysts such as platinum and palladium where costs are paramount and usage needs to be restricted.
- Raney nickel for fat hydrogenation.
