A new type three-stage gasification of dried sewage sludge: Effects of equivalence ratio, weight ratio of activated carbon to feed, and feed rate on gas composition and tar, NH3, and H2S removal and results of approximately 5 h gasification
文摘
A successful three-stage gasification of dried sewage sludge was performed. A ∼5 h gasification showed a high possibility for clean gas production. Activated carbon played a crucial role in tar removal. The minimum tar content in producer gas were 27 mg/Nm3. The minimum NH3 and H2S contents in producer gas were 443 and 470 ppmv.
