Normally, for breaking the structure of lignocellulose, pretreatment strategy was recommended. However, with the increasing pretreatment severity, the pretreated residues and liquor were blacker and blacker.
How to understand this phenomenon and how to avoid the color changes of pretreated residues after pretreatment?
Sincerely!!

Abdulfatah Abdu Yusuf Thanks for your reply.
In one way, I want to dissolve lignocellulose into liquid phase. In another way, I want to avoid the lignocellulose or liquid become black during the dissolution process.
Therefore, I am questioning the mechanisms of lignocellulose or liquid being black after pretreatment at high temperature.
The below mentioned researcher has many articles about such issues. Look specially at the older articles. Happy new year.
