Hydrate formation conditions of twelve synthetic hydrogen + hydrocarbon gas mixtures (H2 + CH4
H2 + C3H8
H2 + CH4 + C3H8
H2 + CH4 + C2H6 + C3H8) were measured in a sapphire cell using the “pressure search” method. The experimental temperature range was 274―280 K
and the pressure range was 0.65―7.0 MPa. The hydrogen content in the gas mixtures varied from 22% to 92%(mol).By using PR equation of state and suitable mixing rule
the Chen-Guo’s hydrate model was extended to calculate the hydrate formation conditions of the hydrogen-containing systems. Satisfactory agreement between experimental data and calculated results were achieved.
