| Abstract: | The treatment of cotton stalk by dilute sulfuric acid was studied,including the hydrolyzing temperature,concentration of the dilute sulfuric acid,the ratio of the cotton stalk and solid content.By orthogonal experiment, it was determined that the hydrolyzing rate reached 29.61% at the following conditions: c(H2SO4)=2.0%,the hydrolyzing temperature 120℃,hydrolyzing time 4 h,and the ratio of solid to liquid 1∶12. |
