Phase equilibrium data of hydrogen in pyrolysis oil and hydrogenated pyrolysis oil at elevated pressures

System bio oil/H2 (a) at pressure 15.7MPa and temperature 383K and (b) at pressure 14.7MPa and temperature 353K. •PE data for CO2/water and H2/water systems.•Pressures from 8.0MPa to 35.0MPa at temperatures of 313.15K, 333.15K, 353.15K.•PE data for the system H2/pyrolysis oil and H2/hydrogenated pyrolysis oil.•Pressures from 3.0MPa up to 17.2MPa at temperatures from 353.15K to 423.15K. Phase equilibrium data for the system hydrogen/pyrolysis oil as well as hydrogenated pyrolysis oils, at temperatures from 353.15K to 423.15K and pressures from 3.0MPa up to 17.2MPa were measured. The procedure was verified by measuring the phase equilibrium data for systems CO2/water and H2/water in the pressure range from 8.0MPa up to 35.0MPa at temperatures from 313.15K up to 353.15K. The high pressure solubility data for above mentioned systems were studied using a static-analytical method in an optical high pressure cell. The solubility increases with pressure at constant temperature, and decreases at increasing temperature. The solubility of bio oils in H2 increases with pressure and with temperature.
