Investigation of Sodium Sulfate Additions into Cryolite-Alumina Melts

http://www.sintef.no/en/publications/publication/?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...

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

http://www.sintef.no/en/publications/publication/?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...

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

http://www.sintef.no/en/publications/publication/?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...

In-situ gas monitoring by laser induced fluorescence spectroscopy

http://www.sintef.no/en/publications/publication/?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...

Hydrogen Fuel Quality Control: high-pressure sampling and analysis

http://www.sintef.no/en/publications/publication/?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...
