Abstract:

To get the high quality cellulose, by studying on the extraction technology of cellulose from peanut hull, the author had determined the technique of more extraction contents of cellulose and bigger removal rate of hemicellulose and lignin. The results showed that the removal rate of hemicellulose was 80.67% under the conditions of NaOH concentration 4%, extracting temperature 50℃, extracting time 2 h. The removal rate of lignin was 47.29% under extracting mixed liquor include both 15 g/L NaClO2 and 31 mL/L acetic acid, extracting temperature 70℃. The content of cellulose extraction was more than 40%. It illustrated that the high quality cellulose with lower contents of hemicellulose and lignin was extracted under the above process conditions.
