A comparative study on the enhanced formation of methane hydrate using CM-95 and CM-100 MWCNTs

Decomposition of methane hydrate for hydrogen production using microwave and radio frequency in-liquid plasma methods

“…The remainder of the ice melted to create hydrates when the cooling bath temperature fell to 2 C [6]. Pressurization at 7 MPa was maintained by repeatedly injecting methane [15]. The pressure remained constant at 7 MPa until the end of the procedure.…”

“…Furthermore, Methane hydrate is increasingly becoming one of the more promising energy resources due to its abundance [12], and potential role in mitigating global climate change [13,14]. It is formed by its constituent CH 4 molecules held within the lattice cavities of water crystals occurring via an exothermic reaction under the proper combination of pressure and temperature [15]. Methane hydrate is an untapped source of hydrocarbon energy [16], which is believed to be both plentiful and stable on the seabed and in permafrost at high pressure and low temperature [10,12,17].…”

“…).46H 2 O[12,14,15,17]. The basic formula for methane hydrate is CH 4 .nH 2 O, where n is the stoichiometric number or hydrate number which describes a variable number of water molecules within the lattice structure of methane hydrate.…”

Adsorption-Hydration Sequence Method for Methane Storage in Porous Material Slurry

“…Zhou et al (2014) found that by adding 0.4% graphite nanoparticle into the water, the induction time of CO 2 hydrate decreased by 80.8% and the CO 2 consumption increased by 12.8%. Kim et al (2011) indicated that the multiwalled carbon nanotubes could accelerate hydrate formation. Pasieka et al (2013) found that both the hydrophobic and hydrophilic multi-wall carbon nanotubes enhanced the hydrate formation.…”

Investigation on the roles of activated carbon particle sizes on methane hydrate formation and dissociation

“…In recent years, natural gas hydrates have gained much attention not only as a new source of natural gas but also as a means for novel applications like carbon dioxide capture, hydrogen storage and natural gas storage and transportation (Ding et al, 2013;Englezos and Lee, 2005;Fan et al, 2014;Kang and Lee, 2000;Kim et al, 2011;Li et al, 2010;Linga et al, 2007;Mandal and Laik, 2008;Sloan, 2003;Veluswamy et al, 2014). Natural gas hydrates, mainly methane, contain highly concentrated methane gas.…”
