Fabrication of carbon fibre composites for gas separation

Carbon fibre composite for ventilation air methane (VAM) capture

“…It was found that surface area increased with the increase in burn-off but this does not reflect the methane adsorption performance of the monolith. This trend is in agreement with the results obtained from Kimber et al [9]. On the other hand, surface area obtained using CO 2 at 0 • C was able to produce a better representation of the methane adsorption performance of the material.…”

“…Recently carbon fibre composites appear to be the most effective adsorbent for the VAM enriching process [8][9][10][11]. This is due to their robust pore structure and the pore size of the carbon fibre composite, which cannot be achieved by conventional activated carbon [12].…”

Post combustion CO2 capture by carbon fibre monolithic adsorbents

“…3 illustrates the fabrication process and summarizes the main fabrication parameters for honeycomb monolithic carbon fibre composite adsorbents (HMCFC). This is similar to the method given in references [54,74,101,119].…”

“…The chemisorption and activation steps were repeated until the desired burn-off was attained (8.5-13.4%). Under favourable conditions, the range of variation of surface area was about 3-6% [56,119]. The only problem with this technique is that the reaction time is much longer than with the conventional methods.…”

Carbon Dioxide Separation from Flue Gases: A Technological Review Emphasizing Reduction in Greenhouse Gas Emissions

“…The results of researchers (Burchell and Judkins [ 138 ], Dave et al [ 28 ], and Yong et al [ 139 ]) indicated that the CO 2 adsorption efficiency of the honeycomb monolith is twice than activated carbon and 1.5 times greater than ZIF material [ 29 ]. Results of Kimber et al [ 140 ] showed that CO 2 selectivity of honeycomb monolithic composite decreased with increasing in burn-off.…”
