Partial anode effect in a two-compartment laboratory alumina reduction cell
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...
Evaluation of Gas Composition from Laboratory Scale Electrolysis Experiments with Anodes of Different Sulfur Content
Hydrogen Fuel Quality Control: high-pressure sampling and analysis
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
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
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...
