Optimization of Concentrated Sulphuric Acid Hydrolysis of Gadam Sorghum Stalks Found in Kenya for Fermentable Sugar Production

Gadam sorghum stalks are agricultural residues which can be hydrolyzed into fermentable sugars that used to produce bioethanol is a renewable source of energy. In order from lignocellulosic biomass such as stalks, several processes including hydrolysis involved. However, the use for production hindered by low yield obtained during hydrolysis. The lack sufficient information on optimal conditions governing leads inefficient process hinders economic viability large-scale production. objective this study was optimize reaction involved in concentrated sulphuric acid stalks. During hydrolysis, were varied included temperature (40°C–80°C), time (30-90 minutes), and concentration (30%-70%, w / ). Central composite rotatable design establish optimum level conditions.
