To begin with, platinum group metal (PGM) electroplating offers a cost-effective alternative to solid PGM components. By applying thin PGM layers onto base metals, manufacturers can significantly reduce material consumption. Among these, platinum (Pt), palladium (Pd), and rhodium (Rh) electroplating are particularly noteworthy…
Recycling Platinum Group Metal Alloy Scrap Platinum group metal (PGM) alloys come in many forms as scrap. Occasionally, factories collect scrap from a single source with a consistent composition. This material may only suffer from surface contamination or physical damage…
Platinum Recovery from Fuel Cell Catalysts New energy has emerged as a critical industry for sustainable development. Significantly, fuel cells represent one of its most promising technologies. Currently, three main types - PAFCs, PEMFCs, and DMFCs - all utilize platinum…
I. Recovery of Ru from Spent Ru/C and Ru/MgO Catalysts In the ammonia synthesis industry, Ru/C and Ru/MgO catalysts are widely used due to their high catalytic activity and ability to reduce operating pressure and temperature. Process for treating spent…
1. Understanding Catalyst Loss Mechanisms Our Pt-Pd-Rh alloy catalyst operates at 800-950°C under 304-912 kPa pressure. During standard operation, the system loses 0.1-0.15g platinum group metals (PGMs) per ton of HNO₃ produced through three primary pathways: First, high-temperature gas streams…
Platinum-rhodium crucibles, bushing plates, and spinnerets melt glass and glass fibers at high temperatures (1200–1300°C) for extended periods. During operation, some platinum and rhodium oxidize into PtO₂ and Rh₂O₃, which then volatilize and either seep into furnace refractory bricks or become trapped in…
Carrier catalysts are widely used in the chemical and petrochemical industries, such as: Anthraquinone process for hydrogen peroxide production Urea synthesis CO removal from synthesis gas in ammonia production Benzene hydrogenation to cyclohexane Catalytic combustion of low-concentration volatile organic compounds…
I. Systematic Comparison of PGM Recovery Technologies The global recycling of platinum group metals (PGMs) from end-of-life automotive catalysts presents multifaceted challenges. To evaluate competing technologies objectively, we must analyze six critical dimensions: First, regarding recovery efficiency, pyrometallurgical methods consistently achieve…
