Abstract

In this study, chestnut shells was pyrolyzed in fixed bed reactor. The effects of pyrolysis temperature, heating rate and sweep gas flow rate on the yields of products were investigated. As a result of the experiments, the maximum bio-oil yield of 18.70% was obtained with the heating rate of 50 oC min-1, at the pyrolysis temperature of 400 oC and sweeping gas flow rate of 150 cm3 min-1. The FTIR and elemental analyses and heating value determination of the obtained the bio-oil were also performed. The obtainedbio-oil was separated into its hydrocarbons and polar compounds in column chromatography. The aliphatic sub-fraction was characterized by GC-MS. In addition, the BET surface areas of the raw material and the solid product were determined and the SEM images of the solid product were taken

Özet

Bu çalışmada kestane kabuğu biyokütle kaynağı olarak seçilmiş ve sabit yataklı reaktörde pirolizi gerçekleştirilmiştir. Deneylerde piroliz sıcaklığı, ısıtma hızı ve sürükleyici gaz akış hızının piroliz ürün verimleri üzerindeki etkileri incelenmiştir. Yapılan deneyler sonucunda en yüksek katran verimine 50 oCdk-1 ısıtma hızı, 400 oC piroliz sıcaklığı ve 150 cm3dk-1 sürükleyici gaz akış hızında %18,70 ile ulaşılmıştır. Çalışmalar sonucunda elde edilen katranın FTIR spektrumu alınmış, elementel analizi gerçekleştirilmiş ve ısıl değeri belirlenmiştir. Katran sütun kromatografisinde hidrokarbon ve polar bileşiklerine ayrılmıştır. Alifatik alt fraksiyon GC-MS ile karakterize edilmiştir. Ayrıca hammaddenin ve katı ürünün BET yüzey alanları belirlenmiş ve katı ürünün SEM görüntüsü alınmıştır.
