Title: KINETICS OF ALKALINE 'HYDROL YSIS OF MILLET COBS FOR GLUCOSE PRODUCTION
Authors: MOHAMMED, S. SIDI ALI

Abstract: ABSTRACT The alkaline hydrolysis of millet cobs for glucose production was investigated in a batch reactor. This was accomplished by the pretreatment of millet cobs (sample) by grinding to reduce their sizes and treating with diethyl- ether to remove extractives. Also hydrolysis of cellulose to D-glucose was carried out using 0.2, 0.3 and 0.4 M of sodium hydroxide solution at temperature ranges of 60-80 DC. The results obtained shows that alkaline hydrolysis reaction follows a first order kinetics and the activation energy obtained was 49.8858 KJ / gmol, the activation energy so obtained for alkaline hydrolysis was lower than that obtained from acid hydrolysis of the same sample (millet cob) which stands at 72.2130 KJ/gmol. This also indicates that millet cob is easier to hydrolysed via alkaline medium. It was found that, for this work the optimum operating temperature was 75 DC while the optimum concentration was 0.2 M with the highest percentage glucose yield of about 1.45 while that of the acid hydrolysis gives higher yield of 2.48 percent.
