In this work, acid-catalyzed steam explosion was carried out as a pretreatment to hydrolyze hemicellulose and increase the enzymatic digestibility of corncob. Pretreatment conditions were varied to achieve structural alterations in a wide range: type of acids (sulfuric acid and oxalic acid), acid concentration (0.1–1.5wt.%) and pressure (1.0–1.8MPa). The pretreated residues were analyzed by chemical...
Cellulose nanocrystals were isolated from oil palm trunk by total chlorine free method. The samples were either water pre-hydrolyzed or non-water pre-hydrolyzed, subjected to soda pulping, acidified and ozone bleached. Cellulose and cellulose nanocrystal (CNC) physical, chemical, thermal properties, and crystallinity index were investigated by composition analysis, scanning electron microscopy, transmission...
