摘要： A process for production of lignins and synthetic gas including the steps of extracting lignins and hemicellulose by putting solid Lignocellulosic Raw Material in contact with a mixture of water and formic acid at atmospheric pressure and at a temperature between 80° C. and 110° C.; fractionating, the primary solid fraction and the primary liquid fraction; separating the lignins from the intermediate liquid fraction; and gasifying at least part of said primary solid fraction and/or at least part of said residual liquid fraction for producing synthetic gas.

摘要： A low energy production method for producing pure and highly concentrated carbon dioxide from a renewable lignocellulosic biomass feedstock comprising the steps of i) extracting lignins and hemicelluloses by putting a solid lignocellulosic raw material in the presence of a mixture of at least water and formic acid, at atmospheric pressure under conditions of temperature between 80° C. and 110° C., ii) fractionating, the primary solid fraction and the primary liquid fraction obtained at the end of the extraction step i), iii) separating the lignins from the intermediate liquid fraction, iv) producing a synthetic gas by feeding a gasification equipment with at least part of said primary solid fraction and/or at least part of said residual liquid fraction, and v) producing carbon dioxide and water by introducing dioxygen, or dioxygen enriched air, or air in said gasification equipment.

摘要： A method and a power plant for on-demand producing electricity from Non-Fossil Power Sources and from a Renewable Lignocellulosic Biomass Feedstock, in a power plant using several electrical production facilities comprising a first facility for producing electricity from a Non-Fossil Power Source chosen from among wind power, hydro power, solar power, geothermal power and/or tidal power; and a second facility using synthetic gas produced during a gasification step of several fractions from renewable lignocellulosic biomass feedstock obtained by the implementation of an organosolv process using a mixture composed of at least water and formic acid.
