Greenhouse gas emissions are a primary driver of global warming.Thus, effective utilization, capture, or conversion of CO2 into clean energy is vital for global environment and industrial development.The formation of CO2 hydrates, however, presents a promising approach to address these challenges.In this study, five different concentrations of pure multi-armed carbon nanotubes (MWCNTs) were tested in three different systems: a binary composite sodium dodecyl sulfate (SDS) system (MWCNTs + 300 ppm SDS), a binary composite dodecyl tri-Me ammonium chloride (DTAC) system (MWCNTs + 300 ppm DTAC), and a ternary composite system (MWCNTs + 300 ppm SDS + 300 ppm DTAC).The experiments investigated the kinetics of CO2 hydrate formation.The results revealed that the gas consumption in all three systems peaked at a MWCNTs concentration of 0.03 mg/mL.At this concentration, the ternary composite system showed a 7.63 % (±1.26 %) higher gas consumption than the binary SDS system, and a 13.62 % (±0.19 %) higher consumption than the binary DTAC system.Induction time decreased progressively with increasing MWCNTs concentration, reaching its shortest value at 0.09 mg/mL.At this point, the ternary composite system exhibited a 43.75 % reduction in induction time compared to the binary SDS system, and a 68.75 % reduction compared to the binary DTAC system.Furthermore, a comparison between the ternary composite MWCNTs system and the ternary composite NH2-MWCNTs system showed that the latter promoted hydrate formation slightly better, though the difference was not significant.This research will contribute to advancing the commercialization of CO2 capture and storage technologies based on hydrate formation.
