For sustainable industries based renewable biomass, secure of raw material is important. Kenaf is a good candidate with fast-growing and high biomass productvity. Acid hydrolysis treatment of kenaf woody core is capable produced high purity cellulose for fine chemical production, which was hydrolyzed hemicelluloses (mainly xylan) to monosaccharides. The effects of various reaction temperatures (110-130℃), and reaction times (60-120 min) were investigated to get the optimum condition. 1 H NMR spectroscopy was used to quantitative analysis of polysaccharide composition based on hydrolzed monosaccharides analysis. The results showed that optimum conditions for acid hydrolysis treatment was 1.00N sulfuric acid, 130℃, and 60 min for higher purity cellulose production with cellulose as 50.0%, hemicellulsoe as 1.2%) and lignin as 0.3% based on raw kenaf core biomass.
