Sewage sludge composition

In this work the parameters of Low Temperature Conversion – LTC were applied in a centrifuged sludge from a sewage treatment plant located in Rio de Janeiro, Brazil. Before the conversion, the sludge was dried and analyzed by TGA to observe its behavior with increasing temperature.

The present work describes an experimental study on sewage sludge pyrolysis in a Fluidised Bed Reactor(FluBR) and the effect on the pyrolysis liquid product of passing the hot exhaust (pyrolysis) vapours through a Fixed Bed Reactor (FixBR) filled with gamma-alumina (c-Al2O3).
