摘要：
The hydrodeoxygenation (HDO) of m-cresol is investigated as a model for the HDO of phenolic compounds from lignin pyrolysis. Pt catalysts supported on gamma-Al2O3 and SiO2 are effective for the conversion of m-cresol to toluene and methylcyclohexane at 533 K and 0.5 atm H-2. Experiments using Pt/gamma-Al2O3 show that the reaction proceeds by a combination of Pt-catalyzed hydrogenation and acid-catalyzed dehydration reactions. Dehydration of a partially hydrogenated oxygenate intermediate is most likely the dominant reaction pathway to toluene. The acidity of the gamma-Al2O3 support was modified by base (K2CO3) and acid (NH4F) treatments, and increasing the number and strength of acid sites was found to increase the rate of HDO. Pt/SiO2 was more active for m-cresol HDO than Pt/Al2O3. The reaction rate on Pt/Al2O3 and Pt/SiO2 decreased after 5 h on stream, but Pt/Al2O3 regained initial reactivity after reductive treatment in H-2.
