“…These processes have been examined for CO 2 capture at pilot-scale, but this technique is costly, requires pre-treatment, and produces large amount of wastewater and sludge. In adsorption process, the added advantages of those solid adsorbents are easy to handle and do not give rise to corrosion problems (Plaza et al 2009;Thiruvenkatachari et al 2009). …”

In the last few decades of industrialization, the concentration of CO 2 in the atmosphere had increased rapidly. Different organizations have invested considerable funds in research activities worldwide for CO 2 capture and storage. To date, significant work has been done and various technologies have been proposed for CO 2 capture and storage. Both adsorption and absorption are promising techniques for CO 2 capture, but low-temperature adsorption processes using solid adsorbents are the prevailing technique nowadays. In this review paper, a variety of adsorbents such as carbonaceous materials, dry alkali metal-based sorbents, zeolites, metal-organic frameworks (MOFs) and microporous organic polymers (MOPs) have been studied. Various methods of chemical or physical modification and the effects of supporting materials have been discussed to enhance CO 2 capture capacity of these adsorbents. Low-temperature (\100°C) adsorption processes for CO 2 capture are critically analyzed and concluded on the basis of information available so far in the literature. All the information in CO 2 adsorption using different routes has been discussed, summarized and thoroughly presented in this review article. The most important comparative study of relatively new material MOFs and MOPs is carried out between the groups and with other sorbent as well.

“…Carbon fibres have been studied extensively for their scientific and technological importance and are finding application in many fields including catalysis [1], composites [2][3][4], filtration [5][6][7], and alternative energy technologies [8]. Carbon fibres are advantageous due to being a light weight material with a high specific modulus and strength, good thermal/electrical conductivity and being structurally stable against various environmental changes [2,9].…”

“…Depending on the precursor material used, the properties of the carbon fibre can vary. For example, pitch-based carbon fibres have greater thermal conductivity than rayon-based carbon fibres, and PAN-based carbon fibres possess higher compressive and tensile strengths compared to pitch-based carbon fibres [5]. In addition to the precursor material, the processing method is also very important in fabricating carbon fibres with desired properties.…”

Electrospun green fibres from lignin and chitosan: a novel polycomplexation process for the production of lignin-based fibres

et al. 2014

Novel lignin-chitosan polyelectrolyte fibres were produced through a reactive electrospinning process. Polyelectrolyte formation between the anionic lignin and cationic chitosan was controlled through the pH of the solution. Through manipulating the polyelectrolyte complex formation, fibres could be effectively produced from two biopolymers, which are normally very difficult to electrospin on their own. Though minimal amounts of the petroleum-derived polyethylene oxide were introduced into the solution to enhance the spinnability of the polyelectrolyte solution, it could be easily removed from the fibres post spinning by washing with water. Thus, pure biopolymer fibres could be produced. The optimum composition of lignin to chitosan was identified through SEM, FTIR and TGA analysis of the electrospun fibres. Fluorescence spectra of the electrospun fibres reveal the homogeneous distribution of lignin and chitosan components throughout the fibre network.

“…To regenerate the solvent, a typical energy penalty incurred for the MEA capture process is an estimated 14% of the net power output of the plant (Rao and Rubin, 2002). Numerous alternatives, such as cryogenic separation, membrane separation, micro algal bio-fixation, and adsorption, are available for sequestering CO 2 from flue gases from the combustion of fossil fuels (Thiruvenkatachari et al, 2009). Adsorption is attractive due to its low energy requirement, low cost, and good cycle performance.…”

Nitrogen-doped activated carbons with high surface areas obtained from resorcinol and formaldehyde resins were evaluated as CO 2 adsorbents in a simulated flue gas stream under anhydrous and humid conditions. These carbons were prepared using two approaches, namely ammonia treatment without nitric acid pre-oxidation and amination after preoxidation. The pre-oxidation of activated carbons considerably enhanced the nitrogen incorporation during the amination process. The amination temperature affects the content and type of nitrogen incorporated onto the carbon surface, as determined by X-ray photoelectron spectroscopy, which enhances the specific adsorbent-adsorbate interaction for CO 2 in humid conditions. The presence of H 2 O in the feed gas significantly decreased CO 2 adsorption for a very low nitrogen content of virgin activated carbon. A sample prepared via the amination of pre-oxidized carbon at 700°C (NORF700) exhibited excellent tolerance to moisture and the highest CO 2 capacity of 2.10 mmol/g in a 7% CO 2 /83% N 2 /10% H 2 O wet stream at 50°C and 130 kPa. The high performance of NORF700 was ascribed to its high surface area, adequate micropore volume, and high amounts of pyrindinic-like and pyrrole-like nitrogen species. The results indicate that nitric acid preoxidation followed by ammonia treatment at 700°C is an appropriate process for preparing adsorbents for CO 2 separation in post-combustion applications.
