Abstract: Hydrogenation of rosin over Pd/C catalysts was studied in supercritical CO2 (scCO2) phase. Comparison of results in scCO2 with those in conventional conditions showed that the product contained lower of abietic and hydroabietic acid. The effects of reaction temperature, reaction times, amount of Pd/C catalysts and the reuse of Pd/C catalysts were studied. The reason of the decrease of catalyst activity was the losing of Pd in Pd/C catalysts when were reused.

Key words: Pd/C catalyst, hydrogenated rosin, supercritical CO2 fluid
