Keywords: , , ,

This Study is aimed to produce bio-ethanol based on the fruit wastes and optimize the bio-ethanol production for a direct ethanol fuel cell(DEFC). Fruit wastes such as pear, apple, persimmon were used in the conditions of acid pre-treatment, at temperature 120oC, period of 90min. Hydrolysis rate of pear at concentration 3% is 11.3%(sulfuric acid), 14.1%(nitric acid), 15.5%(hydrochloric acid). After fermantaion process, concentration of ethanol was about 7%. Using the multi coloumn distillation system, more than 95% ethanol was distilled and each component analysis of bio-ethanol was resulted. The Bio fuel from this multi coloumn distillation method was corresponded with the international standards of Japan, U.S.A. and Brazil etc.. The impurity effects of formic acid for DEFC performence is also analyzed and evaluated.
