In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...

lithium-ion batteries due to their higher energy density and lower associated environmental impacts comparing to the other batteries, recently have been highly considered. the materials used in anode, are one of the most important parts affecting batteries’ energy density and environmental impacts. the aim of this study is to investigate how environmental emissions of different materials as ano...

The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

The recovery of selenium from Iranian sar-cheshmeh copper anode slime has been investigated. Copper anode slimes are containing varying precious metals, such as: gold, silver, selenium and tellurium. They are being extracted as a by-product in the production process. Arsenic and antimony that present in anode slimes dissolved in 0.4 M KOH. Then, the alkaline roasting of anode slimes in the pres...

In this study, ZnFe2O4 (ZFO) nanotapers are fabricated on the ZnO nanorods (NRs) by recycling rare-earth oxide (REO) slag as the iron source, which thereby exhibits dramatically enhanced photoelectrochemical (PEC) efficiency. Our studies demonstrate that the electron-hole separation and charge migration can be facilitated by the cascade band alignment of ZFO and ZnO and the branched nanotaper s...

5-aminosalicylic acid (5-asa) is currently prepared by electrochemical reduction of 5-nitrosalicylic acid (5-nsa) in acidic media. in this work, electrolytic reduction of 5-nsa in alkaline media is presented. reactionconditions and parameters such as anode and cathode electrodes, electrolyte type, reaction time, temperature,current, and the ph for isolation of product are investigated. the yiel...

Recycling of Li-ion battery cathode materials using carbon from the anode via carbothermic reduction would provide a process option that could be carried out without introducing any external reactants. From this basis, study investigated and examined kinetics LiCoO2 at 700 °C to 1100 under inert atmosphere up 240 minutes reaction time an isothermal mass change analysis combined with detailed mi...

The recovery process of selenium from Iranian Sar-Cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. The copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium. They are being extracted as a by product in th...

Deoxidation of Ti, or direct removal of O dissolved in metallic Ti, is known to be extremely difficult when Mg is used as the deoxidizing agent. This difficulty arises because the chemical potential of O2, pO2, under Mg/MgO equilibrium is high (approximately 10(-41) atm at 1200 K) and is equivalent to that of Ti containing ∼2 mass% O at 1200 K. Therefore, when deoxidizing Ti to the commercial l...
