heal.abstract The paper investigates the effects of mild acidic treatment, i.e. prehydrolysis, on the main components of lignocellulosic materials, and based on that, discusses the potential role of prehydrolysis for biomass refining, defined as the systematic fractionation of its main components to a number of high-value intermediates, which could be used by various downstream industries, like oil refinery products. Prehydrolysis was shown to very effectively fractionate hemicelluloses, since more than 90% of this component can be easily saccharified, mostly in monosaccharide form. Under the optimal conditions for hemicellulose fractionation, both cellulose and lignin undergo significant depolymerization; a limited part of their depolymerized oligomers is soluble in the prehydrolysate, whereas considerably more could become solubilized ill subsequent treatment steps, e.g., in alkaline conditions - for cellulose - or by extraction with organic solvents - for lignin. All major aspects of prehydrolysis can he adequately described by a relatively simple reaction engineering model, based on tile concept of ''reaction factor'' which permits to optimize the incorporation of a prehydrolytic stage in a biomass refinery. en
