Menetelmä selluloosan käsittelemiseksi sekä selluloosan käsittelystä saatuja alkaliliuoksia

摘要

In a method for treating cellulose-based raw material hemicelluloses in the raw material are first dissolved in a raw material specific alkali solution. The obtained hemicellulose alkali solution is oxidized for degrading hemicelluloses, and the oxidized alkali solution is re-used in the same process or in another process.
