Recovering Precious Metals from Spent Chemical Processing Catalysts
Most chemical processors use precious-metal-bearing catalysts for facilitating and/or speeding chemical reactions. These catalysts are typically composed of platinum group metals (PGMs). After a number of process cycles the catalysts lose their efficacy and must be replaced with fresh catalysts. Spent catalysts are sent to a precious-metals refiner for recovery and refining of the valuable PGMs remaining in this material. Selecting—and working with—a precious-metals refiner is critical to ensure highest possible returns and peace of mind with regard to environmental concerns.

Properly Model and Control Batch Reactors
This paper covers key aspects for modeling and design of batch reactors, including: heat-up and cool-down performance, sensitivity analysis for reactor parameters, boil-up rate predictions, thermal stability under exothermic conditions, control system design and loop tuning parameters, condenser rating, and process emissions predictions.
Maximize Returns from Precious-Metal-Bearing Catalysts
Many catalytic reactions rely on platinum, palladium and other precious metal catalysts. When the activity of the catalyst declines to the point that it must be replaced, the used catalyst can be sent to a refiner to recover precious metal. This 8-page paper discusses the variouis factors that should be considered when using a refiner.
