THF hydrate is similar to natural gas hydrate regarding to some properties. Furt hermore, comparing with the rigorous condition for generating natural gas hydrat e, which requires low temperature and high pressure, the formation environment o f tetrahydrofuran(THF) is comparatively mild. At atmospheric pressure, it can be generated at around 0 ℃ (the balance temperature is 4.4 ℃). This text analyze s the formation process and condition of THF with experiment observation and stu dies the kinetics law for THF formation at different temperature and consistency . Furthermore, it combines the process of diffusion and reaction, and adjusts th e exponent of mass transfer crystallization area. With the liquid consistency fo rmula, this text specifies the bulk liquid consistency of the module and thus de velops a theory module of kinetics and verifies it.
Key words: Tetrahydrofuran; Hydrate; Kinetics; Gas chromatography.
