HYDROGEN-PRODUCTION FROM WET CELLULOSE BY LOW-TEMPERATURE GASIFICATION USING A REDUCED NICKEL-CATALYST

Wet cellulose was gasified at 350 degrees C for 1 h in the presence of a reduced nickel catalyst under various operating pressures (8-18 MPa ). Hydrogen was obtained specifically at high operating pressures of 1 7-18 MPa. Under the operating pressure of 18 MPa, the gas yield increa sed with catalyst loading and reached 91 wt% at the catalyst loading o f 20 wt%. The gas consisted of hydrogen of 50 vol%, carbon dioxide of 40 vol% and methane of 10 vol%, which was equivalent to that the hydro gen of 70% in the cellulose was recovered as hydrogen gas.
