    Abstract: método para produção de fibras precursoras contendo lignina e tmém de fibras de carbono a presente invenção está correlacionada a um método para produção de um precursor para produção de fibras de carbono e fibras de carbono ativado, de acordo com o método de fiação a úmido ou de fiação em uma abertura de ar, no qual uma solução de lignina e um polímero formador de fibra em um adequado solvente é extrudada através dos furos de um bico de fiação dentro de um banho de coagulação, em que o fio formado é esticado e subsequentemente tratado, seco a uma elevada temperatura e depois enrolado. o fio contendo lignina é um econômico material de partida para a produção de fibras de carbono e fibras de carbono ativado.

    Abstract: Disclosed is a method for the production of a precursor fibre for the production of carbon- and activated carbon fibres according to the wet- or air-gap spinning method, in which a solution of lignin and a fibre-forming polymer selected from cellulose derivatives, in a suitable solvent is extruded through the holes of a spinning nozzle into a coagulation bath, the formed thread is stretched and subsequently treated, dried at an elevated temperature and then wound up. The lignin-containing thread is an economical starting material for the production of carbon and activated carbon fibres. Also disclosed is a method for the production of a carbon fibre from the precursor fibre by carbonising above 800 °C and subjecting the fibre to water vapour.
