Abstract

The results of the experimental studies have been described aimed at the pyrolytic utilization of sewage sludge derived from municipal wastewater treatment plants using the high-pressure steam technology. Experiments have shown that combustible gases are present in the resulting gas composition, and no carbon dioxide or nitrogen oxides have been detected. The relative composition of combustible gases is strongly dependent on the experimental conditions, and their amount corresponds to the dry weight loss of initial sludge obtained by a long-term drying procedure at 110ºC. The solid dry fraction of the pyrolysis products is a dark fine powder without any specific odor that can be easily mixed with water, without consequent powder subsidence during 10 days after its preparation and without making considerable marks on a conventional paper filter of normal density.
