Description
Summary:The impact of the preparation techniques of niobium oxide and two-component systems based on niobium and zirconium oxides on the catalytic properties was studied in the one-pot hydrolysisdehydration of cellulose into glucose and 5-hydroxy methylfurfural. Cellulose transformation was performed in an autoclave at 180 °C under argon atmosphere. The most promising methods for the preparation of solid catalysts were found to be microwave heating and mechanical activation. Glucose and 5-hydroxymethylfurfural can be produced with total yield equal to 20-21 % in the presence of catalysts prepared using these techniques.
