Increasing molecular O3 storage capacity in a clathrate hydrate

摘要: This paper reports an experimental study to further increase the ozone storage capacity in a clathrate hydrate and better understand relationship between gas phase O3 concentration hydrate. We performed experiments with + O2 CO2 feed increased fraction exceeding that covered by preceding study. To accurately specify thermodynamic conditions form hydrate, we first measured three-phase (gas liquid hydrate) equilibrium for (O3 H2O) (O2 systems. The data cover temperature range from 272 277 K, corresponding pressures 1.6 3.1 MPa, each of two different O2)-to-CO2 or O2-to-CO2 molar ratios gas, which are approximately 4 : 6 5 : 5, respectively. was ∼0.025. Based on data, prepared crystal samples hydrates at system pressure 3.0 MPa K. highest be 2.15 mass% is 2.36 times higher than past record 0.91 mass%. results also show dominant factor control mole contact hydrates.
