Abstract

Abstract

In order to expand the utilization of activated sludge, the co-pyrolysis of sludge and wheat straw with different moisture content was studied in a fixed bed reactor. Sludge and straw with different moisture content were mixed and pyrolysis in the range of 600~900 ℃. The effects of pyrolysis temperature, sludge moisture content and straw addition amount on gas composition were studied. When the sludge moisture content was constant, the content of H₂ and CO gradually increased with the increase of reactor temperature. At the same temperature, as the moisture content of sludge increased, the content of H₂ increased first and then decreased, while the content of CO decreased gradually. When the moisture content of sludge was 60%, the content of H₂ reached the maximum value. When the pyrolysis temperature was 800 ℃, 40% straw and sludge with moisture content of 60% was the best proportion to prepare hydrogen-rich syngas.
