MODEL BİYOKÜTLE OLARAK SEÇİLEN MISIRDAN HİDROTERMAL YÖNTEMLE DEĞERLİ KİMYASALLARIN ELDESİ

Bu çalışmada mısır model biyokütle olarak seçilmiş ve suyun kritik altı (225°C, 300°C) ve yakın kritik (375°C) şartlarında bir otoklav içerisinde hidrotermal dönüşüm işlemine tabi tutulmuştur. Bu işlemler sonucunda ele geçen sulu fazların içerisindeki organik asitler (asetik asit, formik asit, glikolik asit vb), fenoller (fenol türevleri, o-kresol, m-kresol vb.), furfurallar (furfural, metil furfural, hidroksimetil furfural vb.) gibi bileşik grupları HPLC (Yüksek basınçlı sıvı kromatografisi) ile analiz edilmiştir. Sulu fazın toplam organik karbon (TOK) içeriğine bağlı olarak yüzde karbon içeriği de hesaplanmıştır. Katı faza ayrıca SEM analizi uygulanarak dönüşüm esnasında katı yüzeyinde meydana gelen değişimler gözlenmiştir.

Anahtar Kelimeler:

Biyokütle, hidrotermal yöntem, mısır
