摘　　要：As a kind of novel environmental-friendly surfactant,Gemini surfactant has attracted extensive research interests in its effects on gas hydrate formation.We investigated the effects of dioctyl sodium sulfosuccinate(AOT)on the formation thermodynamics/kinetics of CH_(4)and CO_(2)hydrates.Experimental results indicate that while AOT does not exhibit significant thermodynamic promotion for hydrate formation,it demonstrates favorable kinetic promotion effects.Its promotion effect surpasses that of the traditional kinetic promoter SDS and can enhance the gas storage capacity of hydrates.Utilizing the Chen-Guo hydrate model and adsorption kinetic model,we established a kinetic model for AOT with a predictive deviation of 7.17%and fitted key parameters accordingly.
