Pyrolysis (1)

Rate and efficiency of the AD process is controlled by:
  • Thermal degradation of molecules at high temperature (300 - 900°C), and in the absence of O2.
  • Pyrolysis of sewage sludge produces:
    • Liquid bio-oil/tar, combustible gases, fixed carbon (biochar), ash and water vapor
  • Consideration of sewage sludge as feedstock or pyrolysis has recently gained attention.
