Hydrogen solubility in methanol, (methanol + carbon dioxide) and (methanol + carbon dioxide + oxygen) was measured and correlated at different temperatures (268 less than T/K less than 288) and pressures (0.37 less than P/MPa less than 3.5). Hydrogen content in the liquid phase was measured using a gas absorption method and Fugatron HYD-100 instrument. Experiments were performed in a fixed volume cell at constant temperature and hydrogen content was varied with subsequent loadings in the cell environment. At all conditions investigated a linear relation between hydrogen partial pressure and concentrationwas observed. Results were correlated and generalized as Henry s constants for H2, as a function of temperature and CO2/methanol overall ratio. Correlation and generalization of the measurements was provided through a thermodynamic model, based on Peng Robinson equation of state with van der Waals mixing rules and Boston Mathias a-function. H2 solubility in methanol was confirmed to grow with temperature and amount of CO2; at constant H2 partial pressure, O2 does not affect H2 solubility.
