چکیده انگلیسی
The storage capacity, induction time and induction temperature of CO2 hydrates were investigated on pure water, SDS solutions, THF solutions and mixtures of THF and SDS. SDS did not present significant effect on increasing storage capacity, as it is usual to methane hydrates. However, mixtures of SDS and THF presented maximum % theoretical, 121(±12) % and reduction of temperature and time for induction, due to a synergistic effect.
► We investigated storage capacity and induction of simple and mixed CO2 hydrates.
► Sodium dodecyl sulfate and tetrahydrofuran were used as additives.
► Maximum enclathration was obtained using mixture of additives.
► We reported synergistic effect due to selective adsorption of ions on hydrate surface.
