Development of Monolithic Materials with and without a Binder with Carbon Molec...
Nabais, Joao; Carrott, Peter; Ribeiro Carrott, Manuela; Galacho, Cristina; Padre-Eterno, AnaIn this work we studied the production of activated carbon fibres in monolith shape from a commercial textile acrylic fibre. The monoliths were produced with and without a binder. The binders tested were phenolic resin, polystyrene, polymethylmethacrylate and clay. We also tested the influence of using a solvent. The SEM analysis indicates that the monoliths are made of filaments that can be considered activate...
New Acrylic Monolithic Carbon Molecular Sieves for O2/N2 and CO2/CH4 Separations
Nabais, Joao; Carrott, Peter; Ribeiro Carrott, Manuela; Padre-Eterno, Ana; Menendez, JAThe modification of activated carbon fibres prepared from a commercial textile acrylic fibre into materials with monolithic shape using phenolic resin as binder was studied. The molecular sieving properties for the gas separations CO2/CH4 and O2/N2 were evaluated from the gas uptake volume and selectivity at 100 s contact time taken from the kinetic adsorption curves of the individual gases. The pseudo-first or...
