We seek to design reaction vessels, i.e. chemical reactors, where a particular chemical reaction (or set of
reactions) is carried out. The first decision we take involves the configuration of the reactor and its mode of
operation. This means we must decide what reactor type (and reactor shape) to select and whether it would be
advantageous to operate in batch or continuous mode.
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).
