Investigation of the kinetics of TBAB + carbon dioxide semiclathrate hydrate in presence of tween 80 as a cold storage material

Effects of Graphene Oxide Nanosheets and Al2O3Nanoparticles on CO2Uptake in Semi‐clathrate Hydrates

“…However, the addition of TBAB to the system leads to a decrease of the moles of gas consumption. Similar to the findings of Mohammadi and Jodat [27] and Mech et al [29], the negative effect of TBAB on the kinetics of CO 2 hydrate in this study was predictable (Fig. 3).…”

“…For example, the mixtures of (15 wt % TBAB + 400 ppm GO) and (15 wt % TBAB + 0.4 wt % Al 2 O 3 ) increased the SC value by 140 and 122 %, respectively, compared to 15 wt % TBAB. Mohammadi and Jodat [27] reported that Tween 80 at 500 ppm enhances the SC up to 7.2 %, which is less than the enhancement of the SC values found in this study.…”

“…Although higher concentrations of TBAB showed a noticeable impact on the alteration of the hydrate stability region to milder conditions, based on the results of this study and previous studies [27,29] Figure 7. Rate of CO 2 uptake in the presence of (TBAB + GO) aqueous solutions within 6 min of reaction.…”

“…3. Mohammadi and Jodat [27] studied the impact of Tween on the kinetics of CO 2 + TBAB hydrates. They found that Tween 80 at a concentration of 500 ppm increases the final mole number of CO 2 uptake up to about 7.2 %.…”

“…Several studies have confirmed that CO 2 could probably be separated from flue gases under the effect of TBAB hydrates [5,25,26]. Mohammadi and Jodat [27] reported that the presence of TBAB in aqueous solution (5-15 wt %) could reduce the number of moles of consumed CO 2 compared to pure water. Another study showed that TBAB (40-45 wt %) can be used as a cold-storage substance in air conditioning processes because it is able to enhance temperature modification and hydrate conversion [28].…”
