METHOD FOR ACTIVATING AND PRECIPITATING LIGNIN |
摘要 |
According to an example aspect of the present invention, there is provided a method of producing reactive lignin from an alkaline lignin containing stream, such as black liquor, e.g. kraft lignin, by using thermal treatment with temperatures between 200 and 250 °C for simultaneous activation (for example by demethylation and/or demethoxylation) and precipitation of the lignin. |
