“…Generally similar results were reported by Alberton et al (2007) and He and Hill (2007) indicating the importance of catalyst type and the highly destructive role of carbon dissolved within the catalyst structure above 873 K. During catalytic and thermal cracking of ethanol in the temperature range from 523 K to 1123 K, Jankhah et al (2008) found that carbon deposits can be formed as filaments, both rectilinear and helicoidal. Essentially, carbon nanotubes (CNTs) are layers of coaxially assembled graphene planes, and their continuous catalytic production was reviewed by Ying et al (2011). A variety of CNTs can exist ranging from single-walled to multi-walled tubes with Young's modulus over 1 TPa and tensile strength about 150 GPa (Paradise and Goswami 2007).…”

AbstractExtensive literature information on experimental thermodynamic data and theoretical analysis for depositing carbon in various crystallographic forms is examined, and a new three-phase diagram for carbon is proposed. The published methods of quantitative description of gas-solid carbon equilibrium conditions are critically evaluated for filamentous carbon. The standard chemical potential values are accepted only for purified single-walled and multi-walled carbon nanotubes (CNT). Series of C-H-O ternary diagrams are constructed with plots of boundary lines for carbon deposition either as graphite or nanotubes. The lines are computed for nine temperature levels from 200°C to 1000°C and for the total pressure of 1 bar and 10 bar. The diagram for graphite and 1 bar fully conforms to that in (Sasaki K, Teraoka Y. Equilibria in fuel cell gases II. The C-H-O ternary diagrams. J Electrochem Soc 2003b, 150: A885–A888). Allowing for CNTs in carbon deposition leads to significant lowering of the critical carbon content in the reformates in temperatures from 500°C upward with maximum shifting up the deposition boundary O/C values by about 17% and 28%, respectively, at 1 and 10 bar.

“…[ 102 ] One reason is that, unlike other bulk nanoporous carbon materials, carbon nanotubes are expensive to prepare although continuous production has been reported. [ 103 ] This is also likely to be the main obstacle for carbon nanotubes to be used as a CO 2 adsorbent on an industrial scale.…”

Carbon capture and storage (CCS) technologies aiming at tackling CO2 emission have attracted much attention from scientists of various backgrounds. Most CCS systems require an efficient adsorbent to remove CO2 from sources such as fossil fuels (pre‐combustion) or flue gas from power generation (post‐combustion). Research on developing efficient adsorbents with a substantial capacity, good stability and recyclability has grown rapidly in the past decade. Because of their high surface area, highly porous structure, and high stability, various nanoporous materials have been viewed as good candidates for this challenging task. Here, recent developments in several classes of nanoporous materials, such as zeolites, metal organic frameworks (MOFs), mesoporous silicas, carbon nanotubes, and organic cage frameworks, for CCS are examined and potential future directions for CCS technology are discussed. The main criteria for a sustainable CO2 adsorbent for industrial use are also rationalized. Moreover, catalytic transformations of CO2 to other chemical species using nanoporous catalysts and their potential for large scale carbon capture and utilization (CCU) processes are also discussed. Application of CCU technologies avoids any potential hazard associated with CO2 reservoirs and allows possible recovery of some running cost for CO2 capture by manufacturing valuable chemicals.
