Atık Mermer Tozu Katalizörlüğünde Haşhaş Yağından Biyodizel Eldesi

Bu çalışmada, mermer atıkları katalizörlüğünde haşhaş yağı ve metanolden, transesterifikasyon tepkimesi ile biyodizel üretimi incelenmiştir. Katalizör olarak kullanılan CaO, toz haline getirilen mermer atıklarının 850 °C’de 3 saat süresince kalsinasyonu ile hazırlanmıştır (verim %43) ve XRD ve SEM-EDX yöntemleri ile karakterize edilmiştir. Biyodizel verimine metanol-yağ molar oranı, katalizör miktarı, tepkime süresi ve sıcaklığın etkisi incelenmiş, bu parametrelerin optimum değerleri sırası ile 6:1, %1, 120 dakika ve 65 °C olarak belirlenmiştir. Elde edilen biyodizelin yakıt özelikleri TS EN 14214 standardı ile karşılaştırılarak belirlenmiş ve dizel yakıt ile karıştırılarak kullanılabileceği öngörülmüştür.

Production of Biodiesel from Poppy Oil by Using Waste Marble Dust as Catalyst

In this study, biodiesel production from poppy oil and methanol, by transesterification reaction, wasinvestigated by using waste marble dust as catalyst. The CaO, used as catalyst, was prepared (yield 43%)by calcination of powdered marble dust at 850 °C for 3 h and characterized by XRD and SEM-EDXtechniques. The effects of methanol: oil molar ratio, catalyst amount, reaction time and temperature onthe biodiesel yield were investigated and optimum values of these parameters were determined as 6:1,1%, 120 min and 65°C, respectively. The properties of the produced biodiesel were determined bycompared with TS EN 14214 standard and it is expected to use with diesel.
