Palladium Leaching Chemistry

Technology Licensing Opportunity - This is not a procurement. Palladium Leaching Chemistry Selectively Recovering Palladium from Palladium-Containing Materials Opportunity: Idaho National Laboratory (INL), managed and operated by Battelle Energy Alliance, LLC (BEA), is offering the opportunity to enter into a license and/or collaborative research agreement to commercialize the Palladium Leaching Chemistry technology. Background: Palladium is a precious metal exhibiting useful properties suitable for a wide range of applications. Palladium can be over 10% of the metal value in e-scrap and is recognized as a critical material of interest to clean energy technologies. Palladium is also used as a catalyst material in industrial processes such as hydrogenation and dehydrogenation reactions and in automotive catalytic converters. Description: Researchers at INL have developed a new process for the extraction of palladium from e-waste feedstocks. One of the most common solutions currently used in palladium recovery processes is hydrogen peroxide in hydrochloric acid. This chemistry is typically operated close to boiling temperature (80'C). INL's process improves upon this common solution with the addition of a low cost reducing agent, which allows for room temperature operation with a fourfold increase in leaching rate. This process complements INL's E-RECOV process by allowing recyclers to extract more value from their e-waste resources. Applications: This process can be applied in metal recycling and refining applications. Possible waste feedstocks include active material from catalytic converters and e-scrap metallic waste streams. Advantages: This method can operate at room temperature and shows recovery rates similar to other leaching processes performed at much higher temperatures. Impact: This process would allow for time and energy savings on current processes. Development: This method has been tested. Further work is being done to optimize the formulation for specific applications. IP Status: Filed US Patent Application No. 16/541,930 - Methods of Selectively Recovering Palladium from a Palladium-Containing Material INL is seeking to license the above intellectual property to a company with a demonstrated ability to bring such inventions to the market. Exclusive rights in defined fields of use may be available.
