Abstract

Bu çalışmada, bir mikroalg olan Spirulina hidrotermal koşullarda bio-yağa dönüştürülmüştür. İlk kısımda (katalizör kullanlmayan deneylerde) farklı hidrotermal proses sıcaklıklarının (250 ile 375°C arasında), farklı ilk basınçların (1 ile 4 MPa arasında) ve farklı reaksiyon sürelerinin (30 ile 120 dakika arasında) biyo-yağ ve katı ürün verimlerine etkisi incelenmiştir. En yüksek biyo-yağ verimi ağ. %36 olarak bulunmuş ve 350 °C’de 30 dakika reaksiyon süresinde ve 1 MPa başlangıç basıncında gerçekleştirilen deneyden elde edilmiştir. İkinci kısımda (katalizör kullanılan deneyler) metal halojenürlerin (CsCl, CsCl-KCl, CsCl-NaCl, CsCl-ZnCl₂, and CsCl-SnCl₂) biyo-yağ verimlerine etkisi ve biyo-yağların bileşimleri incelenmiştir. Deneylerde kullanılan metal halojenürlerin biyo-yağ verimlerine önemli bir etkisi olmamıştır. Biyo-yağın en yüksek dizel yakıt içeriği ağ. %78 olarak bulunmuş ve CsCl-NaCl katalizörü kullanılan deneyden elde edilmiştir. Katalizör kullanılmayan deneylerle karşılaştırıldığında katalizör kullanımı biyo-yağların karbon içeriğini az miktarda artırmış, oksijen içeriğini ise az miktarda azaltmıştır. Biyo-yağların içeriğindeki önemli bileşenler aminler, amidler, pirolidinler, indoller ve pirazinler gibi azot içeren bileşiklerdir. En yüksek ısıl değere (yaklaşık 33 Mj/kg) sahip biyo-yağlar CsCl ve CsCl-SnCl₂ kullanılan deneylerden elde edilmiştir.
