Precious metal bearing catalyst recycling expertise

Refining, Precious Metals & Recycling. We recover and refine precious metals from hydrocarbon and petroleum processing catalysts. Also, our proprietary Pyro-Re® process offers the only pyro-metallurgical recovery of rhenium in the industry. With it, we recover total rhenium content from spent semi-regenerative and cyclic fixed-bed hydrocarbon processing catalysts–and get you a full return. With best-in-class techniques and over seven decades of experience, we deliver the ...

Purification by catalytic oxidation

Most industrial and power applications produce off gases that are harmful to health, the environment or have global warming potential, such as CO2, CO, hydrocarbons etc. As the world is pledging to reduce global warming to below 1.5° C compared to pre‐industrial levels, removing or re‐using these gases is crucial to achieve this target. Catalytic oxidation is a facile and economic process to remove a wide range of impurities from industrial gas streams as part of feedstock, ...
