Abstract

Solidified natural gas storage and transportation technology based on gas hydrates offers advantages such as high safety

low energy consumption and environmental friendliness

showing broad application prospects. Currently

this technology faces challenges including slow CH

hydrate formation rates and limited gas storage capacity

which constrain its industrial development. The formation characteristics of CH

hydrates under the promotion of nanoparticle fluids were investigated. Through macroscopic kinetic experiments

the effects of nanoparticle types (graphite nanoparticles (GNP)

ZnO and CuO)

particle sizes and dispersant sodium dodecyl sulfate (SDS) concentrations on the formation kinetics of CH

hydrates were clarified. The results show that the GNP fluid (mass fraction of 0.5%) has a better promoting effect on CH

hydrate formation than ZnO and CuO fluids. Reducing the particle size of GNP appropriately is beneficial for promoting CH

hydrate formation

shortening induction time

and incr

easing normalized gas consumption (NGC). Increasing SDS concentrations can improves the dispersion stability and mass transfer efficiency of GNP. However

when the SDS concentration reaches the critical micelle concentration (900 mg/L)

hydrate formation is inhibited.
