| dc.description.abstract | In the general processes in producing bioethanol pre-treatment process is an important process to break the lignin structure of the feedstock to yield higher amount of glucose in the hydrolysis process. Scope of this project is on the optimization and effect of dilute acid pre-treatment process on the yield of ethanol from durian seeds waste. Optimum parameter for each process is investigated to yield the highest concentration of ethanol from durian seeds waste. Variations of acid concentration and substrate concentration were investigated to produce the highest glucose content for fermentation process. Yields of glucose from dilute acid pre-treated sample using 0.6% H2SO4 and 5% substrate concentration shows significant value of 23.4951 g/L. Combination of dilute acid pre-treatment and enzymatic hydrolysis using 150U of enzyme able to yield 50.0944 g/L of glucose content higher compared to normal pre- treated sample of 8.1093 g/L. Dilute acid pre-treatment sample also shows stable and efficient yeast activity during fermentation process with lowest glucose content at 2.9636 g/L compared to 14.7583g/L for normal pre-treated sample. Based on the result, it can be concluded that dilute acid pre-treatment increase the yield of ethanol from bioethanol production process. | |
