<p>Production of engine fuel or hydrogen for fuel cells from lignocellulosic material comprises dissolving lignin and the resulting solid cellulosic material phase is hydrolyzed, fermented, pyrolyzed and/or gasified and synthesized to produce methanol, dimethyl ether, methane and/or Fischer-Tropsch products or to produce hydrogen. A method for producing fuel for internal combustion engines or fuel cells from lignocellulosic material comprising: (a) dissolving the lignin in the lignocellulosic material to form a liquid lignin-containing phase and a solid cellulosic material phase containing (hemi)cellulose; (b) hydrolyzing the cellulosic material; (c) fermenting the hydrolyzate to form ethanol; (d) pyrolyzing and/or gasifying the liquid phase to produce an energy-rich gas; and (e) synthesizing the gas to produce methanol, dimethyl ether (DME), methane and/or Fischer-Tropsch products. An independent claim is also included for a second method for producing the same fuel, comprising the above steps (1)-(4), followed by (5) producing hydrogen from the energy-rich gas.</p> |
