Cellulose-based carbon hollow fiber membranes for high-pressure mixed gas separations of CO2/CH4 and CO2/N2
Karousos, Dionysis S.; Lei, Linfeng; Lindbråthen, Arne; Sapalidis, Andreas A.; Kouvelos, Evangelos P.; He, Xuezhong; Favvas, Evangelos P. (Peer reviewed; Journal article, 2020)Carbonized cellulose -based hollow fiber membranes were prepared by dry-wet spinning phase inversion method, followed by carbonization and evaluated in terms of gas separation performance for CO2/N2 and CO2/CH4 mixtures, ... -
Long-term performance of highly selective carbon hollow fiber membranes for biogas upgrading in the presence of H<inf>2</inf>S and water vapor
Brunetti, Adele; Lei, Linfeng; Avruscio, Elisa; Karousos, Dionysis S.; Lindbråthen, Arne; Kouvelos, Evangelos P.; He, Xuezhong; Favvas, Evangelos P.; Barbieri, Giuseppe (Peer reviewed; Journal article, 2022)Biogas is an increasingly attractive renewable resource that needs to be upgraded to meet either the natural gas pipeline quality or the biomethane requirement. The use of carbon membranes is a promising alternative to ... -
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 ...
