Cellulose, from bagasse hydrolysis

The approach "select favorable raw material has a major impact on the selection of pretreatment processes. For example, the poplar responds splendidly to many pretreatments that fail with Douglas fir or pine-based materials (I). Specific tissues and cells of a given biomass raw material will respond quite differently. For example, the rind fiber of sugarcane bagasse behaves quite differently from the pith fiber (11)- In woody species, the selection of tissues low in bark and extractives is an important factor in the ease or resistance to cellulose hydrolysis. Before embarking on development of processes for hydrolysis of a biomass resource, it is highly desirable to exercise discretion with respect to the choice of raw materials at both the species and tissue levels. This idea is all the more important in an initial choice of species and pretreatment process. 

In 1951, a process to degrade cellulosic fibers with H SO was introduced by Ranby for the first time [111]. Since then a series of attempts have been taken to prepare CNC from various cellulosic fibers such as curaua fibers [117], coconut husk [118], cotton and tunicates [119], sugarcane bagasse [120], and wood [ 121 ]. In the acid hydrolysis process a suspension with specific acid concentration for a particular time and temperature based on various sources of fibers is mechanically stirred. Then the reaction is quenched with cold water. Subsequently, the washing process is conducted...
