EXPERIMENTAL STUDY ON PREPARATION OF GASES WITH HIGH H_2 FROM SEWAGE SLUDGE

摘要

Pyrolysis of sewage sludge to produce fuel gases with rich H_2 was carried out in this paper. The effect of pyrolytic temperature upon the yield and composition of fuel gases was dealt with in detail. It concluded that yields of gases increase with the raise of temperature. In the same time, fraction of fuel gases, like H_2, CO, CH_4 increases too, which gave as high as 51. 61% of H_2 in volume and 72. 71% of H_2 +CO+CH_4 in volume.
