Abstract. The hydrogenation of liquid terpenes a-pinene and limonene was carried out in the presence of high-pressure carbon dioxide, using carbon-supported Pt and Pd catalysts. Phase equilibrium data on terpene + CO2 + hydrogen were used to interpret the kinetics of hydrogenation in liquid + vapour systems, close to the critical lines of the mixtures.
