Pilot–Scale Production of Carbon Hollow Fiber Membranes from Regenerated Cellulose Precursor-Part II: Carbonization Procedure
Haider, Shamim; Lie, Jon Arvid; Lindbråthen, Arne; Hagg, May-Britt (Journal article; Peer reviewed, 2018)The simultaneous carbonization of thousands of fibers in a horizontal furnace may result in fused fibers if carbonization residuals (tars) are not removed fast enough. The optimized purge gas flow rate and a small degree ... -
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 ... -
Regenerated cellulose based carbon membranes for CO2 separation; Durability and aging under miscellaneous environments
Haider, Shamim; Lindbråthen, Arne; Lie, Jon Arvid; Hagg, May-Britt (Journal article; Peer reviewed, 2018)Predictive models regarding the aging effect on membrane separation properties are required to estimate the membrane life time with acceptable permeability and selectivity for the respective application. The current article ... -
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 ... -
Techno-economic evaluation of helium recovery from natural gas; A comparison between inorganic and polymeric membrane technology
Haider, Shamim; Saeed, Muhammad; Lindbråthen, Arne; Hagg, May-Britt (Journal article; Peer reviewed, 2019)Natural gas produced at high pressure (50-70 bar) is the only industrial source of helium (He). A membrane separation process may offer a more efficient production system with smaller footprint and lower operational cost ... -
