Synergic effect of graphite nanoparticle(GN) and sodium dodecyl benzene sulfonate(SDBS) on the kinetics of CO2 hydrate formation were systematically investigated at 277.15 K and 3.5 MPa by measuring the surface tensions, CO2 consumption, storage capacity, hydrate formation rate, ratio of water converting to hydrate and induction time. The experimental results indicated that SDBS concentration change led to the dramatic change of the kinetics characteristics of hydrate formation. Relative to the pure water system, the gas consumption, hydrate storage, hydrate formation rate and ratio of water converting to hydrate were increased by 86.4%, 35.8%, 85.1% and 20% in the presence of GN(0.4%) + SDBS(0.04%), respectively.
