MOBİLYA ENDÜSTRİSİ ATIKLARINDAN KATALİTİK PİROLİZ YÖNTEMİ İLE BİYOYAKIT ÜRETİMİ

Bu çalışmada, sarıçam (Pinus sylvestris L.) odun talaşı biyokütle kaynağı olarak değerlendirilmiş, sabit yataklı reaktörde, katalizörlü ve katalizörsüz (termal) pirolizi gerçekleştirilmiştir. Deneylerde piroliz ürünlerinin verimleri üzerine sıcaklık ve katalizör tipi gibi parametrelerin etkisi araştırılmıştır. 0,850-1,60 mm parçacık boyutundaki deney örneklerinin pirolizi; 400, 500 ve 600 °C sıcaklıklarda, 5 °C/min ısıtma hızında ve 30 ml/min sürükleyici azot gazı (N2) akış hızında gerçekleştirilmiştir. Katalizör olarak Na2CO3 ve K2CO3 bazik tuzları ile FeCl3 Lewis asidi kullanılmıştır. Sonuç olarak, sıcaklık ve katalizör tipinin katı, sıvı ve gaz ürün verimlerinde etkili parametreler olduğu belirlenmiştir. Ayrıca odun talaşlarından katalitik piroliz yöntemi ile elde edilen sıvı ürünlerin biyoyakıt veya değerli kimyasal madde olarak kullanılabileceği tespit edilmiştir.

BIO-OIL PRODUCTION FROM CATALYTIC PYROLYSIS METHOD OF FURNITURE INDUSTRY SAWDUST

In this study, scots pine (Pinus sylvestris L.) sawdust was used as biomass resources. Catalyzed and uncatalyzed (thermal) pyrolysis processes were conducted in a fixed-bed reactor. The effects of the parameters on pyrolysis product yields such as temperature and catalysis type were investigated. The pyrolysis of the experimental samples that have a particle size in the range of 0.850-1.60 mm were carried out at the temperatures of 400, 500 and 600 °C at the heating rate of 5°C/min. Nitrogen gas (N2) flow was used at the rate of 30 ml/min during the process. Basic salts such as Na2CO3, K2CO3 and Lewis acid (FeCl3) were used as catalyses. As a result, it was determined that temperature and catalysis types were effective parameters in the yields of char, bio-oil and gas products. Also it was determined that the conversion of wood materials into fuel or valuable chemicals with the pyrolysis method is an applicable technology.
