Mesoporous Activated Carbon Fibers from Lignocelullosic Materials: Adsorption Studies
High surface area and highly mesoporous activated carbon fibers (ACF) were obtained by physical activation of natural precursors (vetiver roots and bagasse) with steam and chemical activation using phosphoric acid. The textural characteristics of the activated were determined by nitrogen adsorption study and mercury porosimetry and showed that interesting porosity were obtained (SBET up to 1600...
متن کاملPreparation and Characterization of High Surface Area Activated Carbon Fibers from Lignin
Activated carbon fibers (ACFs) were successfully prepared from softwood lignin, which was isolated with polyethylene glycol 400 (PEG-400) as a solvolysis reagent, by water steam activation. The pore characterization and adsorption property of ACFs were investigated. The results showed that all the ACFs with more micropores exhibited high specific surface area and total pore volume which increas...

Tri-block copolymers (poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide), represented as EOxPOyEOx), pluronics (F127 = EO106PO70EO106, P65 = EO20PO30EO20, P85 = EO27PO39EO27, P103 = EO17PO55EO17, and P123 = EO20PO70EO20) and cationic surfactants (cethyltrimethylammonium bromide (CTAB)), two surfactant systems, form complex micelles that self-assemble into mesostructured particles w...
متن کاملCarbon Fibers from UV-Assisted Stabilization of Lignin-Based Precursors
Production of high strength carbon fibers from bio-derived precursors is of topical interest. Recently, we reported on dry-spinning of a partially acetylated softwood kraft lignin to produce carbon fibers with superior properties, but the thermo-oxidative stabilization step required a long time due to a slow heating rate needed to prevent the fibers from being heated too rapidly and sticking to...
متن کاملExperimental and Theoretical Study on the CH4 Adsorption by Granular and Microporous Activated Carbon
Adsorbed natural gas (ANG) by Granular Activated Carbon (GAC) has been widely investigated as an alternative to CNG and LNG technologies for storage and transportation of natural gas. In the present work, a theoretical and experimental study was conducted to accurately determine the amount of adsorption of CH4 by GAC. To carry out the experiments, the volumetric method was used up to 4 MPa at c...
