Abstract: 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.

摘要： 利用全透明蓝宝石水合物静力学实验装置测定了12组含氢气体混合物（包括5个二元系、4个三元系和3个四元系）在纯水中的水合物生成条件.将Chen-Guo水合物模型应用于含氢体系水合物生成条件的计算，计算中选用PR状态方程以及刘昆元和汪文川提出的混合规则计算含氢气体混合物的组分逸度系数，并对混合规则中的二元交互作用参数进行了重新回归.实验测定的12组含氢气体混合物水合物生成条件的计算结果和实验结果符合得很好.
