The soybean hull is approximately 5% of raw soybean. This paper proposes the use of this residual hull as a substrate for acid hydrolysis reactions in order to obtain sugars. For this, variations of pressure, temperature and quantities of acid were made. The particle size was also tested using natural hull and ground hull. It was observed that under the pressure of 1.1 atm and the temperature of 120 ° C with 0.20 g of sulfuric acid, the ground hull led to the best sugar production, standing out from the others, with a production of 24.93 g / L.
