英文摘要 | The conversion rate of ice powder(alpha), as a key parameter on evaluation of hydrate formation from ice. gas interface, was calculated by using compressibility non-ideal gas equation. And the Avrami equation and the Arrhenius equation were combined to investigate the kinetic information and influence rule of temperature, pressure, and tetrahydrofuran(THF) on the synthesis of ethylene hydrate from ice. As a result, there is no induction period during the formation of ethylene hydrate from ice. And the ethylene hydrate is rapidly nucleated on the ice surface and grows in the one-dimensional direction with the same rate. The activation energy(E-a) of ethylene hydrate from ice powder is 21.28 kJ/mol at 260.05-269.75 K, which is much lower than that in aqueous phase. The final alpha is 19.20% under the initial ethylene pressure of 4.90 MPa and 269.75 K. The a rises with the pressure from 1.98 MPa to 4.90 MPa and temperature from 250.46 K to 269.75 K. And THF can reduce alpha and conversion efficiency of alpha, which can identify that THF has abnormal inhibition on the formation of ethylene hydrate from ice by molecular size effect. |
