Popis: Isothermal phase equilibrium relations of the CO2 + 1,1,1,2-tetrafluoroethane (HFC-134a) and CO2 + 1,1-difluoroethane (HFC-152a) mixed-gas hydrate systems were measured at 279.15 K. The isothermal phase equilibria of the CO2 + HFC-134a mixed-gas hydrate system exhibit the heterogeneous azeotropic-like behavior derived from the structural phase transition of the mixed-gas hydrate. The CO2 + HFC-152a mixed-gas hydrate system shows neither a structural phase transition nor azeotropic-like behavior.
