Abstract:

Sugarcane bagasse, beet pulp and sweet sorghum stalk are main sugar residue in sugar plants. In order to solve the re-using issue of residue, studies on sugar residue saccarification were conducted. A standard method was used to determine the contents of cellulose, semi-cellulose and lignin of three sugar residues. A self-designed reactor which can bear high temperature and pressure was adopted and cellulose materials were saccharificated by diluted acids hydrolysis. The highest reducing sugar yields of the three sugar residue materials were 69.89%, 64.88% and 70.28%, respectively. Based on data of the reducing sugar yield, reaction conditions were optimized, the influences of each factor on reducing sugar yield from three cellulose materials were analyzed.
