“…The significant parameters in the adsorption process are (1) the temperature and pressure during the adsorption and (2) the pore size distribution of the adsorbent. The cycle of adsorption and desorption is involved in the CH 4 storage process [40].…”

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.

“…The liquefied natural gas (LNG) is stored at the boiling point, 112K (-161ºC) in a cryogenic tank at a pressure of 0.1MPa, where the energy density is approximately a 72% of the total gasoline. This means that 1 volume of LNG corresponds to 600 volumes of natural gas under STP (600 v/v) conditions (Cracknell et al, 1993;Menon & Komarneni, 1998). However, this storage method shows multiple inconveniences, mainly because the LNG increases inevitably the temperature within the tank.…”

“…Revealing information has been obtained through simulation techniques regarding the pores required for the storage of methane. For instance, Cracknell et al 1993 reported a study from a Grand Canonical Monte Carlo (GCMC) simulation, where they compared the methane adsorption on AC with pores showing diverse geometries. It was found that the AC that shows the geometry of parallel plane layers, is also the one that posses the highest adsorption capacity: 166 g/L at 274 K at 34 bar contrasting with results obtained for the zeolites-type geometry, 53.1 g/L, under the same conditions.…”

“…Recently, interest has shifted towards the use of nanoporous materials as a promising alternative to compressing natural gas to high pressures (∼30 MPa) [1,2]. Methane is one of the major components of natural gases therefore its adsorption behavior in confined pores is of practical and theoretical interest [3][4][5][6][7][8][9][10][11][12][13]. Several experimental and theoretical studies addressed the adsorption of methane on carbon-based nanoparticles.…”

Methane adsorption onto single-wall boron nitride nanotubes (BNNTs) and carbon nanotubes (CNTs) was studied using the density functional theory within the generalized gradient approximation. The structural optimization of several bonding configurations for a CH 4 molecule approaching the outer surface of the (8,0) BNNT and (8,0) CNT shows that the CH 4 molecule is preferentially adsorbed onto the CNT with a binding energy of −2.84 kcal mol −1 . A comparative study of nanotubes with different diameters (curvatures) reveals that the methane adsorptive capability for the exterior surface increases for wider CNTs and decreases for wider BNNTs. The introduction of defects in the BNNT significantly enhances methane adsorption. We also examined the possibility of binding a bilayer or a single layer of methane molecules and found that methane molecules preferentially adsorb as a single layer onto either BNNTs or CNTs. However, bilayer adsorption is feasible for CNTs and defective BNNTs and requires binding energies of −3.00 and −1.44 kcal mol −1 per adsorbed CH 4 molecule, respectively. Our first-principles findings indicate that BNNTs might be an unsuitable material for natural gas storage.
