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…
