Characteristics of methane hydrate formation in carbon nanofluids

Experimental investigation of methane hydrate formation in the presence of copper oxide nanoparticles and SDS

“…They also increase the mass transfer capability of the aqueous solution by increasing the available surface area and consequently producing several nucleation sites. These trends are the same as what other investigators have reported (Arjang et al, 2013;Keshavarz Moraveji et al, 2013;Mohammadi et al, 2014;Park et al, 2012;Wang et al, 2012).…”

“…Many investigators have studied different methods to promote this process and one of the most important methods proposed is adding some nanoparticles or surfactants to the aqueous solution (Fazlali et al, 2013;Ganji et al, 2007;Kumar et al, 2013;Lirio et al, 2013;Mohammadi et al, 2014;Zhang et al, 2004Zhang et al, , 2007. Park et al (2012) have investigated the effects of carbon nanofluids on methane hydrate formation. They have concluded that the amount of methane gas consumed during the formation of methane hydrate in the presence of oxidized carbon nanofluid is approximately 4.5 times higher than that in distilled water.…”

High‐efficiency CO2 capture and separation based on hydrate technology: A review

“…Gas consumption, gas storage capacity, hydrate formation rate, and water conversion increased by 86.4%, 35.8%, 85.1% ,and 20% in the presence of 0.4% GN + 0.04% SDBS, respectively. Park et al . and Renault‐Crispo et al .…”

“…Gas consumption, gas storage capacity, hydrate formation rate, and water conversion increased by 86.4%, 35.8%, 85.1% ,and 20% in the presence of 0.4% GN + 0.04% SDBS, respectively. Park et al 47 and Renault-Crispo et al 89 also employed multiwalled carbon nanotubes (MWCNTs) and oxidized multiwalled carbon nanotubes (OMWCNTs) as promoters to improve the rate of CO 2 hydrate formation. Li et al 15 found that the synergic additives of nano-Al 2 O 3 and TBAB were more suitable for CO 2 capture and separation.…”

Graphene Oxide: An Effective Promoter for CO2 Hydrate Formation

“…Further studies showed that the mixture of silver nanoparticles and SDS can significantly enlarge the storage capacity [24]. The CH 4 hydrate formation in presence of multi-walled carbon nanotubes (MWCNTs) and oxidized multi-walled carbon nanotubes (OMWCNTs) was studied and experimental results showed that both MWCNTs and OMWCNTs could accelerated hydrate formation rate and gas consumption in OMWCNTs nanofluids was merely 4.5 times higher than that in pure water [25]. Studies on metal oxide powders, such as silicon, aluminum, zinc, titanium and magnesium oxides, proved that metal oxide powders could cut down the induction time and increase gas consumption during hydrate formation.…”
