Çinko oksit destekli katalizörler, KOH ve K2CO3 bileşiklerinin sulu çözeltileri ile birlikte, emdirme metodu ile
hazırlanmıştır ve kanola yağının metanol ile Yağ Asidi Metil Esteri (YAME) vermek üzere, 298–333 K sıcaklık
aralığında ve metanol/yağ oranları 6/1–15/1 aralığında değişen oranlarda seçilerek yapılan transesterifikasyon
reaksiyonlarında test edilmiştir. KOH ve K2CO3 çözeltileri emdirilerek hazırlanan ZnO destekli katalizörler,
kanola yağının 333 K’de, 12/1 metanol/yağ oranı ile transesterifikasyonunda, sırasıyla %94 ve %96 gibi çok
yüksek bir trigliserid dönüşümü veren aktif katalizörler olarak bulunmuştur. Transesterifikasyon reaksiyonunda,
metanolün etanolden daha reaktif olduğu belirlenmiştir.

Anahtar Kelimeler

Biyodizel, çinko oksit, transesterifikasyon kinetiği, YAME, kanola yağı.
