A new method of lignin production was proposed. The lignin was extracted
from the straw hemicellulose residues through alkaline extraction, ultrafiltration,
and spray drying. The purity of lignin was up to 80 %. This method solved
the water pollution and other problems compared with the traditional method.
The cellulose after extracting lignin could produce microcrystalline cellulose.
Therefore, the high value of lignin and cellulose was achieved.
