Depolymerization Performance of Pd/Al2O3 on Ether Biomass Model Molecules under Continuous Flow Reaction

The ether model molecules BPE (phenylbenzyl ether), diphenyl ether (DPE) and phenoxyethylbenzene (PPE) of lignin were used as degradation raw materials, and Pd-Al2O3 was used as catalyst to react in batch reactor and continuous reactor, respectively. Pd-Al2O3 showed good degradation performance in batch reaction. The catalytic performance of three substances was compared in a flow reactor. The reasons of catalyst deactivation and the products adsorbed on the surface during the hydrogenolysis of BPE were studied.
