Abstract

Are currently invested large amounts of resources in developing of new technologies for the utilization of waste from the agricultural sector and processes aimed at the production of second generation ethanol. One of this technologies is the power ultrasound (US), that is currently being tested in areas such as pre-treatment of cellulosic material and combined method for increasing the reaction rate in fermentation processes. The main goal of this project is to study the best conditions for the lignocellulosic waste peanut (shells) hidrolysis with power ultrasound. For this, it will be chemically characterized peanut shells and evaluated the effect of power ultrasound on lignocellulosic material. To make it possible, it will be employed the technique of response surface, using a central composite design to determinate the variables influence: biomass concentration (peanut shells waste), percentage of power applied, aqueous solutions pH and sonication time on the total reducing sugars production. As a result, it is intended to obtain an effect on wall cell disruption of the lignocellulosic material as the product will be exposed to ultrasonic higher powers, increasing the efficiency of total reducing sugar (ART) production for later ethanol production.
