炭载钌催化剂的微波制备及其水相乙酰丙酸加氢性能
Aqueous phase hydrogenation of levulinic acid to γ-valerolactone on supported Ru catalysts prepared by microwave-assisted thermolytic method
摘要
Abstract
γ-Valerolactone (GVL),as a sustainable platform chemical,were produced through an aqueous phase hydrogenation of biomass-derived levulinic acid (LA) in the presence of supported ruthenium catalysts,in which the catalysts were prepared by solvent-free microwave-assisted thermolytic method.The effects of catalyst support,reaction media,pressure,temperature and LA initial concentration were investigated to obtain the optimum conditions for high γ-valerolactone yield.5% Ru/AC catalyst exhibits a more superior catalytic performance compared with Ru/CNT,Ru/FCNT,Ru/γ-Al2O3-MW and Ru/γ-Al2O3-IM at 100℃ and 2.0 MPa of 0.10 g/mL LA concentration in water solution.This superior performance is attributed to the higher dispersion of metallic Ru over coconut shell activated carbon.GVL can be produced with a good yield of > 99% under optimum conditions,and has the potential to provide a green,renewable platform for biotransformation.关键词
