KALSİYUM ASETAT YÜKLENMİŞ DOLOMİT KATALİZÖRÜ İLE KANOLA YAĞI VE METANOLDEN BİYODİZEL ÜRETİMİ

Abstract

Bu çalışmada, kanola yağı ve metanolün tranesterleşme tepkimesi kalsiyum asetat ile kalsiyum oksit içeriği zenginleştirilen dolomit katalizörlüğünde heterojen sistemde çalışılmıştır. Katalizörler kalsiyum asetat sulu çözeltisinin dolomit üzerine kuruluğa kadar emdirilmesi ile hazırlanmıştır. XRD sonuçları kasiyum asetatın ve dolomit içerisindeki kalsiyum karbonatın kalsinasyon sonrasında kalsiyum oksite dönüştüğünü göstermektedir. Kalsiyum asetat yükleme miktarı, katalizör miktarı, metanol/kanola yağı mol oranı ve tepkime zamanı gibi parametrelerin biyodizel üretimine etkisi incelenmiştir. Dolomit üzerine %7.5 kasiyum asetat yükleme miktarının en yüksek katalitik aktiviteyi gösterdiği görülmüştür. En yüksek biyodizel verimi  % 3 katalizör miktarı, 6:1 metanol/kanola yağı mol oranı, 67.5 ⁰C tepkime sıcaklığı ve 3 saat tepkime süresi koşullarında % 93.8 olarak elde edilmiştir.
