Partial Anode Effect in a Two-Compartment Laboratory Alumina Reduction Cell

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1457815

Most laboratory systems investigating the aluminium production process utilize a single anode set-up. When approaching alumina depletion under constant current conditions in such a system, the potential will increase to high levels (>10 V) and initiate an anode effect and perfluorocarbon generati...

Hydrogen Fuel Quality Control: high-pressure sampling and analysis

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1396611

Quality control of hydrogen fuel requires samples to be taken from the nozzle of the hydrogen refueling station dispenser. Samples should be collected at representative pressures and gas velocities and also over the normal duration of a vehicle refuel-ling protocol. The quality control of hydrogen f...

In-situ gas monitoring by laser induced fluorescence spectroscopy

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1359447

Monitoring of silicon suboxide activity is an important parameter in experiments relevant for silicon metal production. In previous work a reactor with optical access to the reaction zone, by use of a sequence of sapphire, UV fused silica and IR transparent sapphire and CaF2 windows, was designed. I...

Anode effect initiation during aluminium electrolysis in a two-compartment laboratory cell

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1341401

Most laboratory cells used in the investigation of the alumina reduction process use a single anode. When investigating the initiation of the anode effect an approach with more than one anode might give better results, as the probability of obtaining partial anode effect is higher. Additionally, the...

Evaluation of Gas Composition from Laboratory Scale Electrolysis Experiments with Anodes of Different Sulphur Content

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1341394

With the anticipated decrease in available anode raw materials, future anodes are expected to contain higher levels of impurities. Currently the implications of this are being investigated through evaluation of electrochemical performance of anodes and the environmental aspects through gas evolution...

Investigation of Sodium Sulfate Additions into Cryolite-Alumina Melts

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1341391

In the Hall-Héroult process, sulfur impurities may not only emit harmful gases but also reduce current efficiency. To better understand this process, the behaviour of sulfur compounds in a cryolite-alumina melt at 1253 K (980 °C) was investigated in a laboratory cell. Sodium sulfate (Na2SO4) was add...
