“…Although Dai et al proposed a strategy to accelerate the polymerization of RF resins, but it needs a strong acid condition [28]. By using hydrothermal conditions the reaction could also be finished in a short time, but it needs to carry out the reaction at a relative high temperature [29][30][31][32]. RF resin is the most frequently used organic monomer for the synthesis of carbon gels and ordered mesoporous carbon via the organic sol-gel process.…”

“…In this line, different types of conformations, sizes, and textures are been considered for CO2 separation, from the broadly used granular activated carbons or monoliths to advanced nanostructured carbon fibers, fabrics, highly hierarchical and ordered molecular sieves, or graphenebased materials (Wahby et al, 2010;Hao et al, 2011;Jiménez et al, 2012;Wei et al, 2012;Srinivas et al, 2014;Balasubramanian and Chowdhury, 2015;Díez et al, 2015).…”

Biomass Waste Carbon Materials as adsorbents for CO2 Capture under Post-Combustion Conditions

et al. 2016

View full text Add to dashboard Cite

A series of porous carbon materials obtained from biomass waste have been synthesized, with different morphologies and structural properties, and evaluated as potential adsorbents for CO2 capture in post-combustion conditions. These carbon materials present CO2 adsorption capacities, at 25°C and 101.3 kPa, comparable to those obtained by other complex carbon or inorganic materials. Furthermore, CO2 uptakes under these conditions can be well correlated with the narrow micropore volume, derived from the CO2 adsorption data at 0°C ( ) V CO 2 DR . In contrast, CO2 adsorption capacities at 25°C and 15 kPa are more related to only pores of sizes lower than 0.7 nm. The capacity values obtained in column adsorption experiments were really promising. An activated carbon fiber obtained from Alcell lignin, FCL, presented a capacity value of 1.3 mmol/g (5.7%wt). Moreover, the adsorption capacity of this carbon fiber was totally recovered in a very fast desorption cycle at the same operation temperature and total pressure and, therefore, without any additional energy requirement. Thus, these results suggest that the biomass waste used in this work could be successfully valorized as efficient CO2 adsorbent, under post-combustion conditions, showing excellent regeneration performance.

“…Therefore, they need to be further fabricated via pelletization or granulation process with the aid of binders or additives, which can often lead to significant loss in their adsorption performance (Williams, 2001;Davis, 2002;Kadib et al, 2009;Lohe et al, 2009;Wen et al, 2010;Hao et al, 2011). Correspondingly, it is of great promise to directly prepare carbon adsorbents with ordered macroscopic morphologies.…”

Uyama et al dissolved PAN in a mixture of hot DMSO and H 2 O, where cooling of the solution led to the phase separation and resulted in a PAN monolith, and CO 2 uptakes up to 22.6 wt.…”

Solid Adsorbents for Low-Temperature CO2 Capture with Low-Energy Penalties Leading to More Effective Integrated Solutions for Power Generation and Industrial Processes

et al. 2015

CO 2 capture represents the key technology for CO 2 reduction within the framework of CO 2 capture, utilization, and storage (CCUS). In fact, the implementation of CO 2 capture extends far beyond CCUS since it will link the CO 2 emission and recycling sectors, and when renewables are used to provide necessary energy input, CO 2 capture would enable a profitable zero-or even negative-emitting and integrated energy-chemical solution. To this end, highly efficient CO 2 capture technologies are needed, and adsorption using solid adsorbents has the potential to be one of the ideal options. Currently, the greatest challenge in this area is the development of adsorbents with high performance that balances a range of optimization-needed factors, those including costs, efficiency, and engineering feasibility. In this review, recent advances on the development of carbon-based and immobilized organic amines-based CO 2 adsorbents are summarized, the selection of these particular categories of materials is because they are among the most developed low-temperature (<100°C) CO 2 adsorbents up to date, which showed important potential for practical deployment at pilot-scale in the near future. Preparation protocols, adsorption behaviors as well as pros and cons of each type of the adsorbents are presented, it was concluded that encouraging results have been achieved already, however, the development of more effective adsorbents for CO 2 capture remains challenging and further innovations in the design and synthesis of adsorbents are needed.Keywords: CCUS, CO 2 capture, adsorption, energy, material science INTRODUCTION CO 2 CAPTURE AND AN INTEGRATED ENERGY-CHEMICAL SOLUTIONThe atmospheric CO 2 concentration now exceeds 400 ppm (CO2Now.org, 2014), and its continuous increase is believed to be the major factor leading to global warming and climatic change (Crowley, 2000;Held and Soden, 2000;Patz et al., 2005). Kaya et al. and Hoffert et al. have quantified net CO 2 emissions in terms of population, economic activity, and energy-related factors using Eq. 1 (Kaya, 1995;Hoffert et al., 1998).where C is the net CO 2 emission, P is population, GDP is the gross domestic product that is used here as an indicator of economyrelated factor, and E is energy production. Therefore, GDP/P is the Per capita GDP, and E/GDP can be regarded as the energy intensity during production that is closely related to the efficiency of energy utilization. The last term, C/E, represents the carbon intensity during energy production. As for the development of the human society and life quality, it is improper to limit population and production, which means there is no solution to CO 2 reduction from the first and second term in Eq. 1. On the other hand, increase in the energy production/utilization efficiency and control of the carbon footprint during energy processes are the major strategies for CO 2 sequestration (third and fourth term in Eq. 1). The complete decarbonization of energy is believed to be the ultimate solution for the long-term sustainability, ...
