Description
Summary:Biobutanol is a type of alcohol that can be produced from biomass lignocellulose and used as renewable fuel. One of lignocellulose sources as raw material of making biobutanol is bagasse. Bagasse as agriculture waste was useless and did not have a potential benefit for farmers, but in this research it used as raw material because of the high cellulose contained. In this research for producing biobutanol, bagasse pre-treated by using ammonia with various concentrations (0 %, 1 %, 3 %, 5 %, 7%) and hydrolysis with 2 % sulphuric acid for 2 hours and 120 °C. Then the process continued with fermentation. In this step 10 mL Clostridium acetobutylicum bacteria was used and fermentation times were varied (2, 4 and 6 days). The aims of this research were analysed the content of cellulose, hemicellulose, lignin before and after pre-treatment processes and also biobutanol content after fermentation process. The results of this research showed that using 7 % ammonia was the highest lignocellulose content which had 69.68 % of cellulose, 14.39 % of hemicellulose and 9.15 % of lignin. The highest biobutanol content was 0.85 % that produced by using 5 % ammonia in the pre-treatment process and fermented for 6 days.
