Pyrolysis has been investigated as one way of producing sewage sludge-derived biochar (solid pyrolysis residue) which is stable and less toxic than sewage sludge. A significant amount of heat must be provided to the pyrolysis process due to its endothermic character. To make the process economically and energy efficient, the necessary heat can be obtained by the combustion of primary pyrolysis products (pyrolysis oil and gas), however in the case of sewage sludge, attention must be paid to the resulting gaseous pollutants due to high nitrogen and sulphur content. Slow pyrolysis of stabilized sewage sludge in inert helium atmosphere was performed at temperatures 400–800°C in order to examine the influence of pyrolysis temperature on the properties of pyrolysis products and sulphur
distribution amongst these products. Pyrolysis at higher temperatures resulted in lesser biochar yield and promoted gas yield. At temperatures of 500°C and higher, over 50% of energy bound in the input sewage sludge was transformed to liquid and gas products. Finally, the effect of pyrolysis temperature on sulphur distribution amongst pyrolysis products was only marginal.Pracoviště Ústav chemických procesů Kontakt Eva Jirsová, jirsova@icpf.cas.cz, Tel.: 220 390 227 Rok sběru 2019 Elektronická adresa https://www.witpress.com/elibrary/wit-transactions-on-ecology-and-the-environment/231
