Isolation of cellulose from palm empty fruit bunches had been conducted. Isolation was conducted with H 2 O 2 30% and H 2 SO 4 with various concentrations (20, 30, 40, and 50%). Hydrolysis and bleaching processes were performed for 90 minutes. The obtained cellulose was characterized by Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscope (SEM). FTIR analysis confirmed the typical bands of cellulose in the sample. XRD patterns showed increasing H 2 SO 4 concentration on hydrolysis process increased crystallinity of cellulose. However, at H 2 SO 4 concentration more than 40% the crystallinity of cellulose reduced. It was due to the reduction of crystalline part of cellulose.
