Table 1 Characterization of the industrial green liquor used in this work.
From: Pre-treatment of eucalypts biomass towards enzymatic saccharification
Analysis of green liquor | Content (g.L-1) |
|---|---|
Content of sodium sulfide (X) in Na2S | 14.59 |
Content of sodium sulfite (Y) in Na2SO3 | 13.9 |
Content of sodium thiosulfate (Z) in Na2S2O3 | 3.16 |
Total alkali (concentration of alkaline constituents: OH-+HS-+HCO3-) expressed in NaOH | 114.1 |
Active alkali (sum of concentrations of hydroxyl and hydro-sulfite ions including ions formed by hydrolysis of sulfides: OH-+HS-) expressed in NaOH | 43.3 |
Effective alkali (concentration of hydroxyl ions including those formed from sulfides by hydrolysis: OH-) expressed in NaOH | 32.5 |
Sulfidity | 33.7 % |
