HYDRODEOXYGENATION OF ETHANOL ORGANOSOLV LIGNIN TO AROMATIC HYDROCARBONS BY METAL ORGANIC FRAMEWORKS
The chemoselective hydrogenolysis of C-O in ethanol organosolv lignin(EOL)catalyzed by metal-organic frameworks(MOFs)infiltrated with Ni,Cu and Co under mild conditions was achieved in this study.The depolymerization of EOL was processed in the co-solvents of formic acid/water at 200℃ for 8 h with the protection of H2.The efficiency of converting EOL into the hydrocarbons or aromatics depended on the types of catalysts.It increased with the order of Ni-MOF-74 > Cu-MOF-74 > Co-MOF-74 > MOF-74.The converting efficiency as high as 90wt%and the yield of phenols was more than 11wt%.All of the results showed that lignin can be efficiently degraded into aromatic hydrocarbons through the hydrogenation and deoxygenation reaction with MOFs as catalyst.It was also highlighted that MOF-based catalysts were potentially used in the selective cleavage of aryl-ether bonds in lignin and other biopolymers.
