KANOLA YAĞINDAN ÇİNKO OKSİT-DESTEKLİ KATALİZÖR VARLIĞINDA BİYODİZEL ÜRETİMİ

Çinko oksit destekli katalizörler, KOH ve K2CO3 bileşiklerinin sulu çözeltileri ile birlikte, emdirme metodu ilehazırlanmıştır ve kanola yağının metanol ile Yağ Asidi Metil Esteri (YAME) vermek üzere, 298–333 K sıcaklıkaralığında ve metanol/yağ oranları 6/1–15/1 aralığında değişen oranlarda seçilerek yapılan transesterifikasyonreaksiyonlarında 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 çokyüksek 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.
