- Аннотация: A comprehensive study of the two-stage thermal processing of dried sewage sludge (SS) into synthesis gas with a high hydrogen content is carried out. The data of the thermogravimetric (TG) analysis of the studied material are used to determine the kinetic parameters of its decomposition. An experimental study of the pyrolysis of dried SS in a fixed-bed reactor makes it possible to reveal the main regularities in the formation of pyrolysis products (semicoke, tar, noncondensable gas, and water). Using the data of gas chromatography-mass spectrometry, the quality of liquid pyrolysis products is assessed. It is shown that the two-stage thermochemical conversion of the initial material, which combines pyrolysis and the subsequent heterogeneous cracking of volatile pyrolysis products, makes it possible to effectively obtain a fairly pure high-calorie gas, the main components of which are hydrogen and carbon monoxide.
