| Abstract: | Alkaline straw-pulp black liquor is extracted by the organic solvent, chloroform. The organic phase is anti-extracted by hydrochloric acid. Biological alkalies and colorants are obtained.And the black liquor is acidized with carbon dioxide. Lignin and the orange solution are gotten.The orange solution is treated with the ion exchangers. Na2CO3 and carboxylates are acquired.Sugar-pulp is produced from the final solution. The components of black liquor are perfectly transformed into useful materials. It has remarkable environmental,social and economic benefits. |
