Low-temperature Pyrolysis of Poultry Litter for Biofuel Production

Year: 2019

Type: article

Abstract: There was investigated the process of poultry litter (PL) low-temperature pyrolysis in a fluidized bed in an environment of superheated steam at a temperature of 300°C. It was established that the duration of the low-temperature pyrolysis process in a fluidized bed does not exceed 840 seconds, which is significantly less than the duration of the pyrolysis process in a fixed bed (2400 seconds). As a result of the pyrolysis process, the weight loss of a poultry litter sample reaches 50%. After pyrolysis, the carbon content in the poultry litter increases 1.16 times, the oxygen content decreases 2.46 times, and the combustion heat of the poultry litter increases 1.13 times. According to its characteristics, the poultry litter after its treatment by the method of low-temperature pyrolysis approaches lignite.
