EVALUATING WASTE COOKING OILS AS ALTERNATIVE DIESEL FUEL

Restaurant ve evsel atik yaglari, yag asidi esterlerine donusturulmek suretiyle alternatif bir dizel yakiti olarak dizel motorlarinda kullanimi, hem insan sagligi hem de cevresel acidan onemli bir avantajdir. Şimdiye kadar Turkiye’de bu yaglarin sadece kucuk bir yuzdesi toplanarak sabun uretiminde kullanilmistir. Atik mutfak yaglarinin, dizel motorlarinda herhangi bir degisiklik yapilmadan kullanilabilmesi icin motorine yakin degerlere sahip bir yakita donusturulmesi gerekmektedir. Donusturulme isleminde en genel kullanilan metot transesterifikasyon reaksiyonudur. Atik mutfak yaglarinin transesterifikasyon reaksiyonu; serbest yag asidi orani ve su icerigi, kullanilan alkolun kimyasal yapisi, katalizor tipi, reaksiyon sicakligi ve reaksiyon suresi gibi fonksiyonlardan etkilenmektedir. Bu calismada atik mutfak yaglarinin yag asidi esterlerine donusturulerek alternatif dizel yakiti olarak kullanabilirligi incelenmektedir
