While this technology is viewed as a science, there are many misconceptions about how precious metals refiners work with customers, such as how they extract precious metals from spent process catalyst lots and how they provide return values to their customers.B. M. COOK...
Precious metals are recovered from spent catalysts by initially removing the oxide layer contg. the precious metals from the metal substrate by electrolytically treating it. The catalyst is connected as the anode or to the anode in the process and the electrolyte is an organic or mineral acid.年...
Clearly, effectiveness, safety and quality are just as important when choosing a PGM (platinum group metals) reclaimer for spent catalyst precious metals recovery, but sadly no simulations are there to help. Quality of service (QOS) in precious metals refining can be challenging to measure,...
Recovery and separation of palladium from spent catalyst An efficient and complete separation of precious metals from the containing secondary materials has a vital economic impact. Palladium loaded on alumina su... MA Barakat,MHH Mahmoud,YS Mahrous - 《Applied Catalysis A General》 被引量: 87发表...
It refers to the process of recovering platinum metals from spent homogeneous catalyst, including the following steps: (a) providing a furnace containing an underwater injector equipped with liquid fuel; and (b) providing a furnace including a metal stage. (c) recovery of most platinum metals fr...
Incineration is the traditional method used to recovery precious metals from spent catalysts, but it has a number of drawbacks, particularly from an enviro... F+S Group - 《Filtration + Separation》 被引量: 0发表: 2003年 EN-P9 Recovery of precious metal from aqueous solution using surface mo...
The method is a general one; the study shows it works with five monometallic nanoparticles and a library of bimetallic nanoparticles, spanning seven different metals, including platinum, cobalt, and nickel. Northwestern University researchers have developed a new method that can recycle spe...
The precious metals division of UK catalyst manufacturer Johnson Matthey has reached an agreement with Norway-based nitrogen fertiliser producer Yara International for the cooperation and marketing of Yara's nitrous oxide abatement catalyst to combat climate change.(Brief article)...
BASF has completed the carve-out of its mobile emissions catalysts and precious metal services businesses and named the separate legal entity BASF Environmental Catalyst and Metal Solutions (ECMS). The company’s intention to carve out the entity was fir
Preliminary Studies on Simultaneous Recovery of Precious Metals from Different Waste Materials by Pyrometallurgical Method Automotive catalytic converters have a limited life time, after which the catalyst must be replaced or regenerated. The spent catalytic converters contain ... J Willner,A Fornalczyk,...
