PYROLYSIS OF ZINC CONTAMINATED BIOMASS FROM PHYTOREMEDIATION

Key Findings & Data:In the first stage of the study, phytoremediation was first applied to zinc contaminated soil 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 (380 S) 240 cm3 reactor.

💡

Conclusion & Impact:The phytoremediation results indicated that high phytoremediation efficiency (79%) were observed.

Abstract

The objective of this study was to stabilize of zinc (Zn) from soil to pyrolysis solid product. For this aim, phytoremediation and pyrolysis were sequentially applied. In the first stage of the study, phytoremediation was first applied to zinc contaminated soil 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 (380 S) 240 cm3 reactor. The phytoremediation results indicated that high phytoremediation efficiency (79%) were observed. Beside the main property analyses, Zn content and Toxicity Characteristic Leaching Procedure (TCLP) analysis were performed 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.

Özet

Bu çalışmanın amacı, çinkonun topraktan piroliz katı ürününe stabilize edilmesidir. Bu amaçla, ardışık olarak fitoremediasyon ve piroliz işlemleri uygulanmıştır. Fitoremediasyon aşamasında, çinkoyla kirlenmiş topraklar, ayçiçeği (Helianthus annuus), mısır (Zea mays) ve kanolayla (Brassica napus) temizlenmiştir. Hasattan sonra bitkiler, 35 °C/dk ısıtma hızıyla 500°C sıcaklıkta sabit yatak bir reaktörde piroliz edilmiştir. Fitoremediasyon sonuçlarına göre, en yüksek fitoremediasyon verimi %79 olarak belirlenmiştir. Piroliz katı ve sıvı ürünlerinin temel özelliklerinin yanısıra, Zn içerikleri de analiz edilmiştir. Piroliz sonuçlarına göre, kirlenmiş biyokütlelelerdeki Zn içeriğinin katı üründe stabilize edildiği görülmüştür
