摘要：

The pT-behavior of the methane-propane-pentane mixtures with molar ration of the ingredients as 0.50 : 0.35 : 0.15 was studied in the porous media of glass spheres (average diameter about 25 Mm) and in a bulk. It was shown that only slight pressure decreasing of the mixture occurs at whole two-phase (gas + liquid) temperature range. However qualitative difference of the pT-diagrams measured for the mixtures in a bulk and in the porous media was found in one-phase region. Temperature dependence of pressure in the porous media was observed weaker than in a bulk. We assumed that the porous media influence is caused by single-layer and capillary adsorption mechanisms giving rise to the chemical content gradient in the porous media along a pore surface normal.
