Kanola yağından çinko oksit-destekli katalizör varlığında biyodizel üretimi

Çinko oksit destekli katalizörler, KOH ve $K_2CO_3$ 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 $K_2CO_3$ 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.

Biodiesel production from canola oil over zinc oxide-supported catalysts

Zinc oxide supported catalysts were prepared by impregnation method with aqueous solutions of KOH and $K_2CO_3$ and tested for the transesterification of canola oil with methanol resulting in Fatty Acid Methyl Ester (FAME) at the temperature range between 298-333 K and methanol/oil ratios of 6/1-15/1. Both catalysts, KOH and $K_2CO_3$ impregnated into ZnO, were found to be the active catalysts resulting in very high conversion of triglyceride (94% and 96% respectively) for transesterification of canola oil at 333 K with methanol/oil ratio of 12/1. Methanol was found to be much more reactive than ethanol in the transesterification reaction.
