The effect of process parameters during the thermal-expansionary pretreatment of wheat straw on hydrolyzate quality and biogas yield
Original language description
This paper was dedicated to evaluate the impact of thermal-expansionary pretreatment on the quality of hydrolyzate and biogas yield. An aqueous suspension containing 5 % wt. of wheat straw was treated under process temperature 170-200°C with residence time 0-60 min. It has been proved that the organic biomass loss of straw, the rate of disruptions in its microstructure, COD, glucose and acetic acid yields in the liquid phase of hydrolyzate increased with an increasing process temperature and residence time, while acidity decreased. This technology has also significantly increased methane yield. A maximum increase of 41 % was reached at process temperature 170°C and residence time 20 min. Thermal-expansionary treatment is a highly heat-demanded operation. The heat produced in cogeneration has always been significantly lower than the heat required for batch heating.
