摘要: Abstract H-USY was treated with nitric acid solution to remove Al species and thus adjust the mesoporosity acidity. Effects of mesopore acidity zeolite were studied on conversion carbohydrate methyl levulinate (MLE). Low concentration mainly removed extraframework aluminum increase resulted in a slight decrease Both framework some extent under high acid, associating obvious low showed higher yield MLE than H-USY-parent. Generated mesopores improved diffusion limitations, facilitated accessibility reactant sites, promoted formation MLE.
