Aspir Yağları ve Aspir Atık Yağlarından Elde Edilen Biyodizellerin Yakıt Özelliklerinin İncelenmesi

Bu çalışmada, aspir (Carthamus tinctorius L.) ham ve rafine yağlarından üretilen biyodizellerin ve bu yağların kızartmada kullanımı sonucu elde kalan atık aspir ham yağı ile atık aspir rafine yağlarından üretilen biyodizellerin yakıt analizleri yapılmıştır. Aspir; ham yağdan, rafine yağdan, atık ham yağdan ve rafine atık yağlardan üretilen biyodizellerin sırasıyla; 15°C deki yoğunluğu (883,2)-(896,3)-(889,8)-(877,9) kg m-3, 40°C deki kinematik viskozitesi (4,57)-(5,55)-(5,72)-(4,86) mm2s-1, soğuk filtre tıkanma noktası (SFTN) (-8), (-9), (-12), (-11) °C, ısıl değeri (39,857)-(39,137)-(39,095)-(39,508) MJ kg-1, parlama noktası (160)-(150)-(180)-(180)°C, su içeriği (398)-(386)-(206)-(243) mg kg-1, renk (ASTM D1500) (<0,5)-(<0,5)-(<0,5)-(1,2), bakır şerit korozyon bütün yakıtlarda (1a) olarak tespit edilmiştir. Elde edilen sonuçlara göre; aspir ham yağı, rafine yağı ve bunların atık kızartma yağlarından yapılan biyodizellerin EN 14214 standardına göre sadece rafine aspir yağı biyodizeli ve atık ham aspir yağı biyodizellerinin kinematik viskozite değerlerinin yüksek çıktığı, diğer yapılan analizlerde standartlar içinde olduğu görülmüştür.

Investigation of Fuel Properties of Biodiesel Produced from Crude, Refined and Fried Safflower Oils

This study examined the fuel properties of biodiesels derived from safflower (Carthamus tinctorius L.) crude and refined oils, as well as those produced from waste safflower crude oil and waste safflower refined oil generated from frying. Biodiesel produced from safflower crude oil, refined oil, waste crude oil and waste refined oil, respectively; Density at 15°C (883.2)-(896.3)-(889.8)-(877.9) kg m-3, kinematic viscosity at 40°C (4.57)-(5.55)-(5.72)-(4.86) mm2s-1 cold filter plugging point (SFTN) (-8), (-9), (-12), (-11) °C, calorific value ((39.857)-(39.137)-(39.095)-(39.508) MJ kg-1, flash point (160)-(150)-(180)-(180)°C, water content (398)-(386)-(206)-(243) mg kg-1, colour (ASTM D1500) (<0.5)-(<0.5)-(<0.5)-(1.2), copper strip corrosion were determined as (1a) in all fuels. revealing that only the kinematic viscosity values of refined safflower oil biodiesel and waste crude safflower oil biodiesel exceeded the standard specified in EN 14214 for biodiesels derived from safflower crude oil, refined oil, and their waste frying oils, while the other fuel properties were found to be within the established standards.
