Abstract
Sorption of carbon dioxide, methane, and hydrogen in additive poly(5-norbornyl-2-norbornene) was studied at pressures in the interval 0–10 bar and temperatures in the interval 10–60°C. The isotherms obtained were described by the double sorption model including both Langmuir and Henry sorption models. The double sorption model parameters and the gas solFigubility coefficients in the polymer at different pressures and at infinite dilutions were determined. The solubility selectivity values were calculated from the data obtained. The highest solubility selectivity for the CO2/CH4 gas pair is reached at 20°С. Owing to high values of this selectivity, additive poly(5-norbornyl-2-norbornene) can be considered as a candidate membrane material for the separation of gas mixtures containing CO2.
期刊介绍：
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
