Development of a FSC membrane for selective CO2 capture
Sandru, Marius (Doktoravhandlinger ved NTNU, 1503-8181; 2009:164, Doctoral thesis, 2009) -
The Effect of Crosslinking on the Physical Aging of PTMSP Membranes
Suciu, Sandra-Paula (Master thesis, 2017)For post-combustion CO2 capture, membranes with high permeability and relatively high CO2/N2 selectivity are favoured to compete with the commercial amine-based absorption technology. With the highest known CO2 permeability, ... -
Facile and Solvent-free Fabrication of PEG-based Membranes with Interpenetrating Networks for CO2 Separation
Deng, Jing; Dai, Zhongde; Yan, Jiaqi; Sandru, Marius; Sandru, Eugenia; Spontak, Richard J; Deng, Liyuan (Journal article; Peer reviewed, 2018)For nearly two decades, membranes derived from polyethers have served as promising candidate materials for CO2 separation. Due to the inherent tendency of high-molecular-weight poly(ethylene oxide) (PEO) to crystallize and ... -
Investigation of New Polymeric Membranes with Controlled Architecture for CO2 Capture
Prache, Marie Odile (Master thesis, 2012)The capture of CO2 is of high interest in a society concerned by climate change and consequently by greenhouse gas emissions. If the amine absorption or hot potassium scrubbing are widely used, several membrane processes ... -
Optimization of PEG-based membranes and mixed matrix membranes for CO2 capture
Deng, Jing (Doctoral theses at NTNU;2020:35, Doctoral thesis, 2019)Design better CO2 separation membranes for capture CO2 The elevated CO2 concentration has been widely recognized as one of the main factors leading to the increasing serious global warming. To prevent it from continuing ... -
Preparation of Carbon Molecular Sieve Membranes with Remarkable CO2/CH4 Selectivity for High-pressure Natural Gas Sweetening
Lei, Linfeng; Lindbråthen, Arne; Zhang, Xiangping; Favvas, Evangelos P.; Sandru, Marius; Hillestad, Magne; He, Xuezhong (Peer reviewed; Journal article, 2020)Carbon hollow fiber membranes (CHFMs) were fabricated based on cellulose hollow fiber precursors spun from a cellulose/ionic liquid system. By a thermal treatment on the precursors using a preheating process before ... -
Preparation of PVAm/PSf composite hollow fibers for flue gas applications
Johannessen, Petra-Kristine (Master thesis, 2012)Polysulfone (PSf) hollow fibres as support for Fixed-Site-Carrier (FSC) polyvinylamine (PVAm)/PSf composite membranes used for CO2 capture were attempted optimized by increasing the air gap and take-up speed during spinning. ... -
Screening Cellulose Spinning Parameters for Fabrication of Novel Carbon Hollow Fiber Membranes for Gas Separation
Lei, Linfeng; Lindbråthen, Arne; Hillestad, Magne; Sandru, Marius; Evangelos, Favvas; He, Xuezhong (Journal article; Peer reviewed, 2019)Novel carbon hollow fiber membranes (CHFMs) have been, for the first time, prepared from cellulose precursors directly spun with a cellulose/(1-ethyl-3-methylimidazolium acetate (EmimAc) + dimethyl sulfoxide (DMSO)) system. ... -
Spinning Cellulose Hollow Fibers Using 1-Ethyl-3-methylimidazolium Acetate–Dimethylsulfoxide Co-Solvent
Lei, Linfeng; Lindbråthen, Arne; Sandru, Marius; Gutierrez, Maria Teresa Guzman; Zhang, Xiangping; Hillestad, Magne; He, Xuezhong (Journal article; Peer reviewed, 2018)The mixture of the ionic liquid 1-ethyl-3-methylimidazolium acetate (EmimAc) and dimethylsulfoxide (DMSO) was employed to dissolve microcrystalline cellulose (MCC). A 10 wt % cellulose dope solution was prepared for spinning ...
