The purpose of this research is to study the production of ethanol from corn cob and compared by ใช้ถ่านกัมมันต์ as catalyst. Study on optimal conditions for production of ethanol from corn cobEthanol production from corn cob fermentation by yeast fermentation without yeast. Saccharomyses C.TISTR 5339 and fermentation by yeast and activated carbon as catalyst. Study of image properties Physical and chemical solution, ethanol from fermentation, the detection value pH และความหนาแน่น properties obtained from the distillation of ethanolAnd density. The ethanol distilled mixed oil benzyl ratio, 90 / 1080 / 20 production it is E10 and oil E20 and check the quality of fuel oil, density, specific gravity, the pour point and the copper strip corrosion of oil
