ACID HYDROLYSIS OF CELLULOSE FROM CORN COBS
Abstract
This research project studied the acid hydrolysis of cellulose from corn cobs. The steps employed to achieve this project involved extraction of cellulose from corn cobs. Corn cobs is a renewable, cheap and abundant lignocellulosic material being a potential source of fermentable sugars. Corn cobs can be used as a substrate for value added products such as ethanol. This research work studied the glucose production from corn cobs using H2SO4 (sulphuric acid) at different conditions of time, dosage, temperature and concentration of acid. The sample was characterized for the proximate constituents and the results shows that the corn cobs has high cellulosic content. Sugar analysis was carried out to determine the highest yield of glucose. Results shows the highest yield of glucose was gotten at 90 minutes (6.285mg/dl), 0.6M concentration of H2SO4(43.082mg/dl), 20 grams (7.225mg/dl) and 100C(20.40mg/dl). Therefore, H2SO4 has proved to be an efficient catalyst for acid hydrolysis of corn cobs.
