Abstract :
The aim of this study is to stabilize of zinc (Zn) from soil to pyrolysis solid product. For this aim, phytoremediation and pyrolysis were sequentially applied. In the phytoremediation stage, contaminated soil with zinc was cleaned up via sunflower (Helianthus annuus), corn (Zea mays) and rape (Brassica napus). After harvesting, the plants were pyrolyzed at 500°C with the heating rate of 35 °C/min in a fixed bed stainless steel reactor. The phytoremediation results indicated that high phytoremediation efficiency (79%) were observed. Beside the main property analyses, Zn contents were determined on the pyrolysis solid and liquid products. According to pyrolysis results, Zn content of the contaminated biomass species is fixed into the ash/char fraction.
