    Abstract: Sludge taken from a wastewater treatment plant of the petrochemical industry was dewatered and pyrolyzed to produce liquid oil as an alternative fuel via microwave heating. Element contents of dried sludge were 45.9 ± 3.85 wt.% carbon, 7.70 ± 1.43 wt.% hydrogen, 4.30 ± 0.77 wt.% nitrogen and 3.89 ± 0.52 wt.% sulfur. Two major thermal degradation peaks of sludge were determined during the microwave pyrolysis process, one at 325–498 K (most of the water was vaporized, and the weight loss was over 85 wt.%) and the other at 548–898 K for sludge constituent decomposition. Zn content was high in the dried raw material and residues. Other toxic elements such as Ni, Cr, Pb, As and Cd contents were 0.61–0.99, 0.18–0.46, 0.15–0.25, 0.018–0.034, and 0.006–0.017 mg/g, respectively. About 14–20 wt.% of oil was produced based on the dried sludge cake, and the oil major elements were C (69–72 wt.%), H (5.7–6.7 wt.%), N (1.9–2.2 wt.%), and S (0.58–0.82 wt.%). The heat values of liquid oils were 8700–9200 kcal/kg at 400–800 °C.
