Abstract:Transfer
hydrogenolysis of diphenyl ether (DPE), a lignin model
compound, was studied from the viewpoint of the reaction kinetics.
Nearly 90% of DPE degradation and formation of aromatic products were
demonstrated at 235 °C with the combination of 2-propanol (IPA)
as a hydrogen-donating solvent and NiCo/C as a non-noble metal catalyst.
Kinetic modeling of reaction results indicated the dominance of direct
hydrogen transfer from IPA to DPE over the other possible pathway
(indirect transfer via H2 gas). However,… Show more
