Method of extracting butyric acid from a fermented liquid and chemically converting butyric acid into biofuel

摘要: Disclosed is a method of converting butyric acid contained in fermentation broth into biofuel. This chemical conversion includes separating biohydrogen from gases generated the course production through carbohydrate, extracting using an insoluble solvent, esterifying thus producing butylbutyrate, and hydrogenolyzing all or part obtaining butanol. Thereby, biobutanol can be efficiently economically produced, which has oxidation stability superior to that conventional biodiesel (fatty methyl ester) regarded as novel biofuel, produced together.
