AYÇİÇEĞİ KÜSPESİNİN PİROLİZİNDE BORİK ASİTİN BİYOÜRÜNLERE ETKİSİ

İkbal Ay Keçeli1 , Bahattin Aydınlı2

Bu çalışmada, ayçiçeği küspesi gibi endüstriyel tarımsal atıkların değerlendirilmesiyle sürdürülebilir bir yöntem olan piroliz işlemi sırasında borik asit katkısının biyoürün verimliliği üzerindeki etkileri araştırılmıştır. Deneysel çalışmalarda karşılaştırma açısından katkısız biyokütle ve %6.6 oranında borik asit katkısı uygulanmış ayçiçeği küspesi numuneleri 400, 450, 500 ve 550?°C sıcaklıklarda pirolize edilmiştir. Elde edilen katı, sıvı ve gaz ürünler kantitatif olarak değerlendirilmiştir. Bulgular, borik asit katkısının özellikle düşük sıcaklıklarda biyokömür verimini artırdığını, yüksek sıcaklıklarda ise sıvı ve gaz ürünlerin oranını azalttığını göstermiştir. Borik asit katkısının piroliz verimi açısından sınırlayıcı etkiler gösterebildiği gözlenmiştir. Çalışma, borik asit katkısının piroliz sürecini ve sonucunu etkilemesi açısından başka çalışmalara önemli bir temel oluşturmaktadır.

EFFECT OF BORİC ACİD ON BİOPRODUCTS İN PYROLYSİS OF SUNFLOWER MEAL

İkbal Ay Keçeli1 , Bahattin Aydınlı2

This study investigated the effects of boric acid addition on bioproduct efficiency during the pyrolysis process, which is a sustainable method, by evaluating industrial agricultural wastes such as sunflower meal. In the experimental studies, for comparison, unmixed biomass and sunflower meal samples with 6.6% boric acid addition were pyrolyzed at 400, 450, 500, and 550°C. The solid, liquid, and gaseous products obtained were evaluated quantitatively. The findings showed that boric acid addition increased biochar yield, especially at low temperatures, while it decreased the ratio of liquid and gaseous products at high temperatures. It was observed that boric acid addition may have limiting effects in terms of pyrolysis efficiency. The study provides an important basis for other studies in terms of the effect of boric acid addition on the pyrolysis process and result.
