Lignocellulosic biomass is the main source of lignins, second most abundant biopolymers.  Long-time regarded merely as by-products of pulping processes, lignins are becoming the major biopolymers available from forest biorefineries in the actual context of pulp and paper industry transformation. We have developed a new organosolv process based on catalytic organosolv pulping with ethanol –water mixture of trembling aspen wood, using ferric chloride as catalyst. The organosolv lignin issued from this process is sulphur- free, with low contents of ashes and carbohydrates. Its relatively high glass transition temperature is favourable for transformation into carbon fibre.  We have successfully extruded this lignin in molten state without any addition of other polymer materials. After the successive temperature stabilization of thus obtained lignin fibres under oxygen followed by nitrogen, the carbon fibres were produced. Their mechanical properties were determined to be convenient for carbon fibres application in various composite materials have been obtained
