Abstract:

To get the high quality cellulose, by studying on the extraction technology of cellulose from bagasse, the author had determined the technique of more extraction content of cellulose and bigger removal rate of hemicellulose and lignin. The results showed that the best reaction condition was that NaOH concentration was 4%, H2O2 concentration was 0.7%, extracting temperature was 85℃, NaClO2 concentration was 9.5 g/L. Under the condition, the content of cellulose extraction was 82.73%, the removal rate of lignin was 94.44%, and the removal rate of hemicellulose was 75.54%.
