One-pot direct catalytic conversion of cellulose to light hydrocarbon at low temperature (443 K) in the presence of Pt-supported catalysts and water was investigated. Pt supported on H^+-form ultra-stable Y-type (H-USY) zeolite catalyst (Pt/H-USY) enabled direct conversion of cellulose into C_3 and C_4 hydrocarbons without hydrogen and other expensive reagents. Results revealed that the pre-treatment of catalyst was important for selective olefin production. Air-oxidized Pt/H-USY catalyst showed higher olefin selectivity than the catalyst reduced with hydrogen. The Pt/H-USY catalysts showed high stability under the reaction condition.
