The conditions for the formation of methane and methylcyclohexane hydrate were measured in the temperature range of 2 73 .60 ~ 2 90 .62 K by means of constant temperature pressure search. The experimental results show that the hydrate (H type) phase equilibrium pressure ratio The phase equilibrium pressure of methane hydrate (type I) is lower than 1.0 MPa. According to the Langmuir isothermal adsorption theory, the mathematical model of phase equilibrium calculation of gas hydrate type H is given. The calculation results show that the model can predict the experiment well System hydrate (H type) formation conditions
