摘要: Abstract Liquid-phase hydrogenation of methyl levulinate was studied over graphite-supported ruthenium (Ru/graphite), zeolite-supported ruthenium, and a mixture Ru/graphite zeolites in water at 343 K. The final γ-valerolactone yield the ZSM-5 showed highest activities between Ru/graphite, Ru/ZSM-5, several zeolites. Methyl hydrogenated to 4-hydroxyvalerate or directly supported metal sites converted acid sites. contained both highly dispersed particles number rather than those catalysts, which led yield.
