Intensification of Wheat Straw Pretreatment by Thermomechanical Process for Enhancement of Sugar Recovery

Z. Maache-Rezzoug, T. Maugard, A. Nouviaire & S.A. Rezzoug
Wheat straw is an interesting source for ethanol production; this abundant raw material has high cellulose content. Wheat straw was pretreated with a thermomechanical process developed in our laboratory to increase the enzymatic hydrolysis extent of potentially fermentable sugars. This process involves subjecting the lignocellulosic biomass for a short time to saturated steam pressure, followed by a flash decompression to vacuum at 50 mbar. Increasing of the heat induced by the saturated steam result in...
