영문 초록

The conditions of anaerobic digestion and biogas reforming have been investigated and optimized for the construction a system for effective hydrogen production from food waste. A cubical reactor with hydrofoil agitator exhibits the highest biogas production for 60 days without a significant fluctuation. As a result, 84 L of biogas is produced from 1 kg of food waste. Reaction temperature and steam/methane ratio are investigated to promote hydrogen production in the biogas steam reforming reaction. The optimized reaction conditions include a reaction temperature of 700 ℃ and H2O/CH4 ratio of 1.0. Under these conditions, hydrogen can be produced via steam reforming of biogas generated from a two-stage anaerobic digestion reactor for 25 h without significant deactivation.
