METHOD FOR MAKING A LIGNIN COMPONENT, A LIGNIN COMPONENT AND ITS USE AND A PRODUCT |
| 摘要 |
The invention relates to a method for making a lignin component from lignin material by an acid treatment, the method comprising: forming a lignin component of lignin material by treating the lignin material in at least one acid treatment stage; and optimizing process conditions by means of a combination of process parameters comprising retention time, temperature and pH level at the acid treatment stage so that the retention time is over 6 hours during at least one acid treatment stage. Further, the invention relates to corresponding lignin components, a use of the lignin component and a product. |
