Abstract: The pyrolysis of sewage sludge, produced by Chiang Mai University wastewater treatment plant, was performed in a fixed bed reactor. The proximate analysis, elemental analysis and calorific value of the sewage sludge were determined. The effects of final pyrolysis temperature and nitrogen flow rate on the pyrolysis yields and chemical compositions were investigated. The particle size of sludge samples was £ 0.25 mm. The maximum liquid yield of 26.90 % by wt. was obtained at final pyrolysis temperature of 500oC with a heating rate of 5 oC min-1 and nitrogen flow rate of 50 cm3min-1. The chemical characterization results showed that the oil obtained from sewage sludge can be potentially valuable as fuel and chemical feed stocks with a calorific value 37.42 MJkg-1.
