Abstract

Abstract: Pd/C catalyst was prepared by deposition-precipitation method with the mass fraction of Pd 4% and the activated carbon supports were modified with HNO₃,HCl,H₂O₂ and NH₃·H₂O,respectively.The specific surface area,pore structure,point of zero charge(PZC) and metallic dispersion of activated carbon were carried out in order to account for the effects of activated carbon modified with different reagents on catalytic activity of Pd/C catalyst in the rosin disproportionation.The results showed that the surface area and pore diameter of activated carbon modified with NH₃·H₂O increased,and the point of zero charge also enhanced.They were beneficial to well metallic dispersion on the surface of carbon materials.The Pd/C catalyst reached the highest catalytic activity,with the yield of dehydroabietic acid up to 81.7% under the conditions of 0.03% catalyst input at 280℃ for 2 h.

Key words: rosin disproportionation, activated carbon, modification
