All societal activities depend up on energy services to meet the daily. The environmental issues,rnthe growing demand for energy, increasing petroleum-based oil prices and the depletion ofrnpetroleum created the need for the development of sustainable and safe alternative energy source.rnBioethanol is one of the alternative energy sources. In this study of ethanol production from cornrncob dilute sulfuric acid method of hydrolysis was employed because it is easy and productivernprocess. The samples were mixed with distilled water in a ratio of 1:10 (w/v) and pretreated usingrn1% dilute sulfuric acid in autoclave at temperature of 120â„ƒ for 30 minutes. It was hydrolyzedrnusing diluted H2SO4 of 2%, 3% and 4% at a temperature of (100 â„ƒ, 120 â„ƒ and 140 â„ƒ) for (20,rn30 and 40) minutes. Sugar concentrations were determined using phenol sulfuric acid method.rnThe maximum, medium and minimum sugar yields were 53.56536, 47.46514 and 41.64815 g/lrnrespectively. Fermentation was conducted using the hydrolysates(sugars) obtained in previousrnprocess, inoculum level of (5, 10, 15 %v/v) and temperature of (25, 30, 35 â„ƒ) for 72 hours. Sugarrnconcentration and inoculum level have a statistically significant effect on ethanol yield with pvaluernofrn0.0021rnandrn0.0068rnrespectively.rnEthanolrnyieldrnwasrnmaximumrnatrnmiddlernvaluesrnofrnthernrnfermentationrnparametersrnandrnitrnisrnnegativelyrnaffectedrnatrntheirrnminimumrnandrnmaximumrnvalues.rnrnFromrnthernstatisticalrnanalysisrnmaximumrnethanolrnyieldrnofrn0.530rnmL/grnwasrnfoundrnatrnsugarrnofrn4.917rnrng,rninoculumrnofrn12.17rn%v/v,rnandrnatrnarntemperaturernofrn29.977rnâ„ƒrnwithrn89.8rn%rndesirability.rnInrnFTIR,rnrnitrnwasrnobservedrnthatrnthernethanolrnproducedrnfromrncornrncobrncontainsrnO-Hrnfunctionalrngroup,rnC-O,rnCH2,rnandrnCH3rngroups.rnFinally,rnarngoodrnyieldrnofrnethanolrnwasrnobtained.rnSo,rncornrncobrnisrnarnpotentialrnrnfeedstockrnforrnethanolrnproduction.
