A comparison was made between the hydrothermal pretreatment of biomass and a mixture Cellulose containing the individual model compounds in the same composition ratio. Thus, rice straw biomass and the Hemicellulose mixture containing cellulose, xylan, and lignin were treated in an autoclave reactor at temperatures between 150 Xylan and 250 °C for 30 min. The obtained products were then subjected to enzymatic hydrolysis. Interestingly, dif- Lignin ferent results were obtained for the two samples, as the presence of cross-linking between cellulose and lignin in the original biomass sample aﬀected the eﬃciency of hydrothermal pretreatment. A model was therefore pro- posed to account for
