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

• PE data for CO2/water and H2/water systems.
• Pressures from 8.0 MPa to 35.0 MPa at temperatures of 313.15 K, 333.15 K, 353.15 K.
• PE data for the system H2/pyrolysis oil and H2/hydrogenated pyrolysis oil.
• Pressures from 3.0 MPa up to 17.2 MPa at temperatures from 353.15 K to 423.15 K.

Phase equilibrium data for the system hydrogen/pyrolysis oil as well as hydrogenated pyrolysis oils, at temperatures from 353.15 K to 423.15 K and pressures from 3.0 MPa up to 17.2 MPa were measured. The procedure was verified by measuring the phase equilibrium data for systems CO2/water and H2/water in the pressure range from 8.0 MPa up to 35.0 MPa at temperatures from 313.15 K up to 353.15 K. 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.
