FUEL GAS PRODUCTION FROM PAPER WASTES IN HIGH-TEMPERATURE LIQUID WATER
Production of fuel gas from the paper wastes, which cannot be recycled, is a promising technique from the view point of establishing a sustainable society. We carried out gasification of paper wastes in water at 523 K to produce fuel gas, such as methane and hydrogen, in a batch reactor. The order of the catalytic activities for the gasification among charcoal-supported metal catalysts was: ruthenium > rhodium > platinum > palladium. The charcoal supported ruthenium catalyst (Ru/C) was the most effective for the gasification of paper and cellulose in water. The gas yield of paper gasification over Ru/C was higher than that of cellulose powder. The gas yields were increased by a ball-milling treatment of recycled paper and cellulose powder, indicating that the gasification rates of paper and cellulose over Ru/C increased with decreasing cellulose crystallinity. Printed paper was also gasified at 523 K in water, demonstrating that fuel can be produced from paper wastes using this technique.
