AYÇİÇEĞİ KÜSPESİNİN PARÇACIK BOYUTUNUN PİROLİZ ÜRÜN VERİMİNE ETKİSİ

İkbal Ay Keçeli1 , Bahattin Aydınlı2

Yapılan çalışmada, biyokütle olarak kullanılan ayçiçeği küspesinin elenmesi sonucunda elde edilen farklı boyutlardaki örneklerin 450°C sabit sıcaklıkta gerçekleştirilen geleneksel piroliziyle elde edilen katı, sıvı ve gaz ürünlerinin verimlerinde parçacık boyutunun etkisi incelenmiştir. Altı farklı boyutta hazırlanan numuneler (150µm den 1.18mm’ye kadar) 450°C’de pirolize edilmiştir. Piroliz sonucunda, parçacık boyutunun ürün dağılımı üzerinde önemli bir rol oynadığı gözlemlenmiştir. Sonuçlar; orta boyutlu (600µm) örneklerde en yüksek biyokömür veriminin (%31.5), en küçük boyutlu numunede (A-150µm) %48 ile en yüksek sıvı ürün veriminin ve en büyük parçacıkta (1.18mm) ise %31.5 ile en yüksek gaz veriminin olduğunu göstermiştir. Bu bulgular, parçacık boyutunun ısı transferi ve tepkime kinetiğine etkisi olduğunu ortaya koymaktadır. Ayçiçeği küspesi gibi endüstriyel tarımsal atıkların enerjiye dönüştürülmesi açısından optimum parçacık boyutunun seçilmesi süreç verimliliğinin ve ürün kalitesinin artmasına sebep olacaktır. Ayrıca, çalışmada atıklardan elde edilen biyokütle kaynaklarının enerjiye kazandırılmasıyla birlikte karbon içeriği yüksek ürünlere dönüştürülerek sürdürülebilir üretim açısından önemli bir katkı oluşturacaktır.

EFFECT OF PARTICLE SIZE OF SUNFLOWER MEAL ON PYROYSIS PRODUCT YIELD

İkbal Ay Keçeli1 , Bahattin Aydınlı2

In this study, the effect of particle size on the yields of solid, liquid, and gas products obtained by conventional pyrolysis of different-sized samples obtained as a result of sieving sunflower meal used as biomass at a constant temperature of 450°C was investigated. Samples prepared in six different sizes (from 1.18mm to 150µm) were pyrolyzed at 450°C. As a result of pyrolysis, it was observed that particle size played an important role on the product distribution. The results showed that the highest biochar yield (31.5%) was in the medium-sized (600µm) samples, the highest liquid product yield was 48% in the smallest sized sample (A-150µm) and the highest gas yield was 31.5% in the largest particle (1.18mm). These findings concluded that particle size affects heat transfer and reaction kinetics. Selecting the optimum particle size for the conversion of industrial agricultural wastes such as sunflower meal into energy will increase process efficiency and product quality. In addition, the study will make an important contribution to sustainable production by converting biomass resources obtained from waste into energy and into products with high carbon content.
