One-pot direct catalytic conversion of cellulose biomass into valuable chemicals, such as C_3 and C_4 hydrocarbons, at low temperature (443 K) in the presence of Pt/H-USY zeolite catalysts and water were investigated. Acidic properties of Pt/H-USY zeolite catalysts were characterized by NH_3-TPD, which played important roles for the Pt-supported state and the formation of C_3 and C_4 hydrocarbons. To clarify the reaction intermediate for the C_3 and C_4 hydrocarbons, catalytic conversions of various substrates were conducted. Results suggested that C_5 compounds (xylose and furfural) might be imermediates of C_3 hydrocarbon formation, while C_6 mono- and di-saccharides (cellobiose, glucose, and fructose) might be intermediates of C_4 hydrocarbon formation from cellucose over Pt/H-USY zeolite catalyst.
