recovery of nickel from spent catalysts by hydrometallurgical method
there are no appreciable amounts of nickel resources in iran; therefore, secondary resources of this element are to be more considered in future. spent nickel catalysts that are used in various industrial processes are one of them. for example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...
متن کاملHydrometallurgical Recovery of Nano-Palladium from Spent Catalyst
Hydrometallurgical recovery of nano-palladium (Pd) from spent Pd/Al2O3 catalyst has been investigated. The Pd content in the spent catalyst sample was assayed to be 0.42% while the remainder was mainly aluminum oxide. Mixture of HCl and AlCl3 was studied as leaching agent for the sample. The Pd was deposited with formic acid. Different parameters affecting leaching and deposition processes such...
متن کاملRecovery of Palladium from Spent Activated Carbon-Supported Palladium Catalysts
TÜBİTAK Marmara Research Center, Chemistry Institute, 41470 Gebze, Kocaeli, Turkey Email: [email protected] Activated carbon-supported palladium catalysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that n...
متن کاملSeparation and Recovery of Platinum and Palladium from Spent Petrochemical Catalysts Using Activated Carbon, Analysis of Two Kind of Most Used Catalysts in Petro Chemistry
The goal of this work is the separation and recovery of platinum and palladium from spent catalyst. The recovery consisted of separating the maximum amount of platinum and palladium from catalysts and changing them into usable forms. The petroleum and petrochemical units use Pt and Pd catalyst for reactions such as reforming and hydrogenation. Because these materials contain valuable metals...
متن کاملHydrometallurgical Recovery of Metals from Large Printed Circuit Board Pieces
The recovery of precious metals from waste printed circuit boards (PCBs) is an effective recycling process. This paper presents a promising hydrometallurgical process to recover precious metals from waste PCBs. To simplify the metal leaching process, large pieces of PCBs were used instead of a pulverized sample. The chemical coating present on the PCBs was removed by sodium hydroxide (NaOH) tre...
