摘要
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·H2 O 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.关键词
