Post combustion CO2 capture using aqueous amine solvents: Investigations on molecular structure-activity relationships for amine solvents
(Doctoral dissertations at TUC;2015:3, Doctoral thesis; Peer reviewed, 2015-06-25)The study in this dissertation focuses on chemical absorption of CO2 using aqueous amine which is expected to be the technology of choice for early large scale deployment of postcombustion carbon capture (PCC). However ... -
Process analytical technology for real-time quantitative speciation of aqueous phase CO2 capture solvents
(Doctoral dissertations at the University of South-Eastern Norway;31, Doctoral thesis, 2019-04-08)Dependency on fossil fuel energy systems is unavoidable until there is a complete shift to alternative energy systems which have no/less impact for global warming. Rapid deployment of carbon capture and sequestration (CCS) ... -
Production of polysilicon from silane pyrolysis in a fluidized bed
(Doctoral dissertations at TUC;2013:3, Doctoral thesis; Peer reviewed, 2013-06-07)The photovoltaic industry has experienced a tremendous growth over the last years.
