| 英文摘要 | A novel hydrogenolysis process for lignosulfonate depolymerization was proposed using a noble metal catalyst cooperated with metal chloride in methanol. hydrogenolysis performance was significantly affected by the catalysts, via a synergistic catalytic effect between the lewis acid (metal chloride) and the noble metal. reaction conditions were also optimized, with 8.6% aliphatic alcohols and 9.2% monomers obtained at 280 degrees c for 5 h over pt/c cooperated with crcl3. analysis of the depolymerized products indicated that crcl3 had a catalytic promoting effect on cleavage of beta-o-4 bonds with the synergistic catalytic effect of pt/c. meanwhile, the noble metal catalysed saturation of the depolymerized products and suppressed them from condensing into residues. the sulfonic groups of lignosulfonate were cleaved and they did not cause pt/c poisoning. the catalyst showed good recyclability, with no significant loss of catalytic activity after three runs. |
