The Start-Up of Continuous Hydrogen Production Process by Anaerobic Fermentation of Food Waste and Glucose

Abstract

Abstract-Continuous biohydrogen production process by anaerobic fermentation of glucose was successfully started-up and the average hydrogen yield of 68.6 ml/gcarbohydrate removed was obtained. When the feedstock converted into the mixture of food waste and glucose, the highest hydrogen yield of 77.4 ml-H 2 /g-VS removed in average was achieved at the food waste proportion of 50%. The biogas was not produced any more feeding sole food waste, indicating the failure in the start-up of biohydrogen production process by anaerobic fermentation of food waste by substrate acclimatization.
