“…Under these conditions, CO2 capacities fall to the range of 0.7-1.2 mmol/g. It is worthy to highlight that these values are still higher or equal than those reported from some commercial carbon-based adsorbents, i.e., Norit R2030 CO2 (Plaza et al, 2015), BPL (Chue et al, 1995), Norit AC 1 Extra (Dreisbach et al, 1999), BrightblackTM (Hornbostel et al, 2013), or VR-5-M (Wahby et al, 2010), very similar to some carbon fiber composites obtained by petroleum pith (Thiruvenkatachari et al, 2013), or even to other attractive adsorbents such as some MOFs (Krishna and Van Baten, 2012;Li et al, 2012;Sabouni et al, 2013;Xu et al, 2013;Xian et al, 2015) and zeolites (Hefti et al, 2015), tested under similar operating conditions. In addition, it should be kept in mind that these materials would present the added value of having being prepared by valorization of highly available underutilized biomass residues and using much more inexpensive, straightforward, and easy to scale-up procedures.…”

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.

“…The CH 4 storage capacity of an AC is ~14 wt% at 298 K and 35 bar [83]. The textural properties of ACs can be controlled by various activation factors and preparation [84][85][86][87][88]. In particular, the adsorption capacity of ACs as adsorbents for gas storage is influenced by the pore structures.…”

Global warming is considered one of the great challenges of the twenty-first century. In order to reduce the ever-increasing amount of methane (CH 4 ) released into the atmosphere, and thus its impact on global climate change, CH 4 storage technologies are attracting significant research interest. CH 4 storage processes are attracting technological interest, and methane is being applied as an alternative fuel for vehicles. CH 4 storage involves many technologies, among which, adsorption processes such as processes using porous adsorbents are regarded as an important green and economic technology. It is very important to develop highly efficient adsorbents to realize techno-economic systems for CH 4 adsorption and storage. In this review, we summarize the nanomaterials being used for CH 4 adsorption, which are divided into non-carbonaceous (e.g., zeolites, metal-organic frameworks, and porous polymers) and carbonaceous materials (e.g., activated carbons, ordered porous carbons, and activated carbon fibers), with a focus on recent research.

“…Dreisbach reported the high-pressure adsorption of CO 2 on Norit R1 carbon measured at 298 K up to a pressure of 60 bar, while fitting the experimental data to the dual-site Langmuir isotherm. [82] According to the authors, the amount of adsorbed CO 2 on this commercial activated carbon approached ca. 12 mmol g À1 at a pressure of 56.3 bar.…”

Adsorbent Materials for Carbon Dioxide Capture from Large Anthropogenic Point Sources

2009

Since the time of the industrial revolution, the atmospheric CO(2) concentration has risen by nearly 35 % to its current level of 383 ppm. The increased carbon dioxide concentration in the atmosphere has been suggested to be a leading contributor to global climate change. To slow the increase, reductions in anthropogenic CO(2) emissions are necessary. Large emission point sources, such as fossil-fuel-based power generation facilities, are the first targets for these reductions. A benchmark, mature technology for the separation of dilute CO(2) from gas streams is via absorption with aqueous amines. However, the use of solid adsorbents is now being widely considered as an alternative, potentially less-energy-intensive separation technology. This Review describes the CO(2) adsorption behavior of several different classes of solid carbon dioxide adsorbents, including zeolites, activated carbons, calcium oxides, hydrotalcites, organic-inorganic hybrids, and metal-organic frameworks. These adsorbents are evaluated in terms of their equilibrium CO(2) capacities as well as other important parameters such as adsorption-desorption kinetics, operating windows, stability, and regenerability. The scope of currently available CO(2) adsorbents and their critical properties that will ultimately affect their incorporation into large-scale separation processes is presented.
