The combination of the thermal and enzymatic hydrolysis promises to be a suitable process for the conversion of lignocellulosic biomass, e.g., rye straw, into sugars, e.g., glucose, xylose, and lignin. The enzymatic hydrolysis of the solid residue after the thermal pretreatment was optimized achieving high glucose concentrations and high conversions of cellulose to glucose with a low enzyme consumption. The lignin of the thermal and enzymatic hydrolysis showed comparable results to the sulfur free lignins derived by the other pretreatments, thus, suitable for high quality lignin applications. The enzymatic hydrolysis was realized under pressure to achieve a lower enzyme consumption and shorter reaction time. Pressure ≤ 300 bar increased the thermal stability of the corresponding enzymes. Thus, elevated temperatures could be applied to increase the reaction rate. This is an abstract of a paper presented at the 7th European Congress of Chemical Engineering-7 and 19th International Congress of Chemical and Process Engineering CHISA 2010 (Prague, Czech Republic 8/28/2010-9/1/2010).
