Abstract

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.
