Hydrometallurgical 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 کاملKinetics Study on Molybdenum Leaching from Spent Catalyst in Ammonium Hydroxide Solution
The aim of the present work is to study the kinetics of leaching process of spent catalyst Ni, Mo/Al2O3 in order to recover the molybdenum using ammonium hydroxide. The investigation depends on the results of previous work ( Mousa et al, 2012). The experiments were conducted in 1-liter stainless steel autoclave. Kinetics study showed that both the diffusion through ash layer and the reaction on...
متن کاملElectro-recovery of nickel from spent catalyst (solid waste) coming out from nitrogenous fertilizer industry
Spent catalysts are principally solid waste which that coming out from nitrogenous fertilizer industry, during the production of ammonia, resulting in the production of large amount of solid waste containing nickel, which is the spent or deactivated catalysts. These catalysts contain from 12-14% nickel based on the production process in fertilizer industry disposal of spent catalyst is a proble...
متن کاملRecovery of Palladium from a Spent Automobile Catalyst Leaching Solution by a Thiodiglycolamide Derivative
In the sequence of previous research on the development of novel liquid-liquid amidetype compounds to efficiently and selectively extract platinum-group metals (PGMs) from concentrated hydrochloric acid media, a specific thiodiglycolamide derivative – N,N’dimethyl-N,N’-dicyclohexylthiodiglycolamide (DMDCHTDGA) – has been applied for the recovery of palladium(II) from a spent automobile catalyst...
متن کاملrecovery 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...
