     organosolv methods can be used to delignify lignocellulosic crop residues for pulp production or to pretreat them prior to enzymatic hydrolysis for bioethanol production. in this study, organic solvent was used as an acidic hydrolysis catalyst to produce glucose. hydrolysis experiments were carried out in 5–20% formic acid at 180–220 °c. wheat straw pulp delignified with a formicodeli™ method was used as a raw material. it was found that glucose yields from pulp are significantly higher than yields from microcrystalline cellulose, a model component for cellulose hydrolysis. the results indicate that cellulose hydrolysis of real fibers takes place more selectively to glucose than hydrolysis of microcrystalline cellulose particles does. the effect of the particle size on pulp hydrolysis was investigated, the crystallinity of hydrolyzed pulp was measured by xrd analysis, and the product distribution and its influence on the process was discussed.
