Process Optimization of Hemicelluloses Lye Extraction from Sugarcane Bagasse

Abstract:

Article Preview

Sugarcane bagasses were used as raw materials to produce the hemicelluloses, and the effects of temperature, alkali consumption, time and liquid to solid ratio on the extraction yield of hemicelluloses were investigated. Through the analysis of the response surface method, results were concluded that the best extraction process conditions were as follows: NaOH concentration 10.60%, extraction time 4.34 h, solid-liquid ratio 1:40.59, actual extraction rate is 31.486%, corresponding to the model prediction 31.4447% basically.
