Statistical Optimization of Bioethanol Production from Corn Stover Biomass

Ketema Beyecha Hundie*

The goal of the study was to find out optimum parameters on conversion of cornstover biomass to renewable fuel. The pretreatment of cornstover was carried out utilizing potassium hydroxide. The result indicated that the important elements of this biomass were cellulose, hemicellulose, and lignin, 34.03, 22.6 and 15.1% respectively. The experiment and statistical evaluation was carried out using response surface methodology. The optimized variables were derived from the quadratic model and selected primarily based on the highest desirability. The result shows that, the optimum parameters were, acid concentration; 2.334 (w/w %), particle size; 0.153 mm, temperature; 144.976 0C and time; 77.233 minutes. At these parameters, the yield of glucose and xylose were, 48.69 and 33.091% respectively. 27.1 g of ethanol concentration was investigated after 48 h of fermentation time at optimized conditions.
