    Abstract: Biosludge can be reused as an adsorbent after ZnCl2 activation, pyrolysis, washing with HCl and distilled water, and drying. But the pyrolysisexhaust of ZnCl2immersed sludge can be hazardous to human health and the environment. The chemical composition, including carbon, nitrogen, hydrogen, sulfur and 21 trace elements, as well as the physical characteristics, including specific surface area, pore volume, pore size distribution and pore diameter of pyrolytic residue, were investigated in this work. In addition, the components of pyrolytic exhaust including 30 VOC species and 5 odorous sulfur gases were determined to evaluate the exhaustcharacteristics. The results indicated that the pyrolytic temperature was higher than 500 °C, the specific surface area could be over 900 m2/g, and the total pore volume could be up to 0.8 cm3/g at 600 °C. Exhaust concentration fractions of VOC groups were about 65–71% oxygenated VOCs, 18–21% chlorinated VOCs, 4–6% aromatic VOCs, and 6–10% acrylonitrile and cyclohexane under the specific conditions in this study.
