“…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].…”

“…Similarly, σ c from phenolic resin in x and z-directions is estimated as ∼0.42 S cm −1 and ∼0.12 S cm −1 , respectively. These values are about two to three orders of magnitude lower than those of carbon fiber derived from isotropic pitch, which has a higher electrical conductivity of 200 S cm −1 [10]. The low electrical conductivity of coated carbon from phenolic resin appears to result from the porous nature of the coated carbon and low carbonization temperature.…”

Porous ceramic fiber composites were coated with pyrolytic carbon by the decomposition of either propane or infiltrated phenolic resin in a nitrogen atmosphere at 800-900 • C. The amount of carbon coating was varied to tailor the electrical conductivity of the carbon-coated composites. The electrical and thermal conductivity of the composites were measured at room temperature using a two-point method and a hot-wire one, respectively. Up to 30 wt% pyrolytic carbon, the electrical conductivity σ showed linearly increasing tendency and was fitted by the effective conductivity according to the parallel rule of a mixture σ = V i · σ i with an effective conductivity of pyrolytic carbon σ c and volume fraction of coated carbon V c . The electrical conductivity of coated carbons prepared from propane at 900 • C and phenolic resin at 800 • C was of the order of 10 0 and 10 −1 S cm −1 , respectively.

“…The operational principles of adsorption require a flow of gas through vessels, which is difficult to accomplish at large diameters, but long reactors produce a significant pressure drop [15]. A petroleum pitch based honeycomb monolithic carbon fibre composite adsorbent [134] demonstrated a methane adsorption capacity, which corresponds to a micro-pore width of 2.14 nm, the optimum pore width generally considered to be ideal for methane adsorption [135].…”

ABSTRACT:Anthropogenic emissions of non-CO 2 greenhouse gases such as fugitive methane contribute significantly to global warming. A review of fugitive methane combustion mitigation and utilisation technologies, which are primarily aimed at methane emissions from coal mining activities, with a focus on modelling and simulation of ultra-lean methane oxidation/combustion is presented. The challenges associated with ultra-lean methane oxidation are on the ignition of the ultra-lean mixture and sustainability of the combustion process. There is a lack of fundamental studies on chemical kinetics of ultra-lean methane combustion and reliable kinetic schemes that can be used together with computational fluid dynamics studies to design and develop advanced mitigation systems. Mitigation of methane as a greenhouse gas calls for more efforts on understanding ultra-lean combustion. Recuperative combustion provides a promising means for mitigating ultra-lean methane emissions. Progress is needed on effective methods to ignite and to recuperate and retain heat for oxidation/combustion of the ultra-lean mixtures. Catalysts can be very effective in reducing the temperatures required for oxidation while plasmas may be utilised to assist the ignition, but thermodynamic/aerodynamic limits of burning ultra-lean methane remain unexplored. Further technological developments may be focussed on developing innovative capturing technology as well as technological innovations to achieve effective ignition and sustainable oxidation/combustion.
