    Abstract: Pyrolysis enables ZnCl2 immersed biosolid to be reused, but some hazardous air pollutants are emitted during this process. Physical characteristics of biosolid adsorbents were investigated in this work. In addition, the constituents of pyrolytic exhaust were determined to evaluate the exhaust characteristics. Results indicated that the pyrolytic temperature was higher than 500 ?C, the specific surface area was >900 m(2)/g, and the total pore volume was as much as 0.8 cm(3)/g at 600 ?C. For non-ZnCl2 immersed biosolid pyrolytic exhaust, VOC emission factors increased from 0.677 to 3.170 mg-VOCs/g-biosolid with the pyrolytic temperature increase from 400 to 700 ?C, and chlorinated VOCs and oxygenated VOCs were the dominant fraction of VOC groups. VOC emission factors increased about three to seven times, ranging from 1.813 to 21.448 mg/g for pyrolytic temperatures at 400-700 ?C, corresponding to the mass ratio of ZnCl2 and biosolid ranging from 0.25-2.5.
