Bio-Binders and its Carbonization and Interaction with Petroleum Coke during Baking
Jahrsengene, Gøril; Rørvik, Stein; Støre, Anne; Wang, Liang; Skreiberg, Øyvind (Peer reviewed; Journal article, 2022)To reduce the carbon footprint in aluminium production, bio-based binders are suggested to replace some or all coal tar pitch in the carbon anodes. In this study, bio-binders based on Norwegian spruce and birch woods were ... -
Cathode Wear in Electrowinning of Aluminum Investigated by a Laboratory Test Cell
Wang, Zhaohui; Nobakhtghalati, Saeid; Støre, Anne; Solheim, Asbjørn; Tschöpe, Kati; Ratvik, Arne Petter; Grande, Tor (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2016)The lifetime of an aluminum electrolysis cell is mainly determined by the cathode wear, especially for high amperage cells utilizing graphitized carbon cathodes. The cathode wear mechanisms are, however, complex and still ... -
Charcoal and Use of Green Binder for Use in Carbon Anodes in the Aluminium Industry
Sommerseth, Camilla; Darell, Ove; Øye, Bjarte Arne; Støre, Anne; Rørvik, Stein (The Minerals, Metals & Materials Series;2367-1181, Chapter; Peer reviewed, 2020)Carbon anodes for aluminium production are produced from calcined petroleum coke (CPC), recycled anode butts and coal tar pitch (CTP). The CO2 produced during anode consumption contributes to a substantial amount of the ... -
Contact angle screening and asymmetric dual-phase CO2 separation membranes
Xing, Wen; Støre, Anne (Peer reviewed; Journal article, 2022)Dual-phase CO2 separation membrane consisting of molten carbonates confined in a solid matrix can separate CO2 at high temperatures. The contact angle of molten carbonates to different oxides that can potentially serve as ... -
Dissolution and Online Monitoring of Nd and Pr Oxides in NdF3-PrF3-LiF Electrolytes
Senanu, Samuel; Ratvik, Arne Petter; Gudbrandsen, Henrik; Martinez, Ana Maria Cuellar; Støre, Anne; Gebarowski, Wojciech (Peer reviewed; Journal article, 2021)Concentrations of dissolved rare earth metal oxides, Nd2O3, and Pr2O3 or their mixtures in different fluoride electrolytes composed of NdF3, PrF3, and LiF at ca. 1040 °C were monitored using a graphite probe inserted into ... -
Perfluorocarbon Formation During Rare Earth Electrolysis
Osen, Karen Sende; Martinez, Ana Maria Cuellar; Gudbrandsen, Henrik; Støre, Anne; Sommerseth, Camilla; Kjos, Ole Sigmund; Aarhaug, Thor Anders; Gaertner, Heiko; Chamelot, Pierre; Gibilaro, Mathieu; Massot, Laurent (Journal article; Peer reviewed, 2018)A challenge during rare earth (RE) electrolysis is to avoid emissions of perfluorocarbon (PFC) green-house gases. The objective of this work was to study how to operate the RE electrolysis process with neither PFC formation ... -
PFC Evolution Characteristics During Aluminium and Rare Earth Electrolysis
Kjos, Ole Sigmund; Solheim, Asbjørn; Aarhaug, Thor Anders; Osen, Karen Sende; Martinez, Ana Maria Cuellar; Sommerseth, Camilla; Gudbrandsen, Henrik; Støre, Anne; Gaertner, Heiko (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2018)In addition to aluminium electrolysis, the electrolysis of rare earth (RE) metals from fluoride melts is a significant source of perfluorocarbon (PFC) emissions to the atmosphere. These processes have many similarities, ... -
PFC evolution characteristics during aluminium and rare earth electrolysis
Kjos, Ole Sigmund; Solheim, Asbjørn; Aarhaug, Thor Anders; Osen, Karen Sende; Martinez, Ana Maria Cuellar; Sommerseth, Camilla; Gudbrandsen, Henrik; Støre, Anne; Gaertner, Heiko (Journal article; Peer reviewed, 2018) -
Recovery of Platinum Group Metals From Secondary Sources by Selective Chlorination from Molten Salt Media
Martinez, Ana Maria Cuellar; Osen, Karen Sende; Støre, Anne (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2020)The use of molten salts as “solvents” offers interesting possibilities for the treatment of ores, industrial by-products as well as scraps, allowing the development of processes that are mid-way between pyro- and ...
