Abstract:
Heterogeneously catalyzed transesterification of natural oil with ethanol over various modified dolomites was studied in this research. The preparation of dolomites were performed via a conventional precipitation method using various divalent and trivalent metals. Influences of a variety of metals, calcination temperature, ethanol/oil molar ratios, reaction time, catalyst amount, and catalyst reusability have been investigated. The results indicated that the calcination temperature of the parent dolomite is a crucial factor affecting the activity and the basicity of the resulting catalyst. The catalyst modified from dolomite calcined at 800 degrees exhibited the most active catalyst, giving the ethyl ester content as high as 97.8 percent under the suitable reaction conditions, the ethanol/oil molar ratio of 18, amount of catalyst of 5 percent wt., the reaction temperature under 70 degrees with reaction time 24 h offered the best yield of fatty acid ethyl esters. The chemical structure of bioester products were studied by nuclear magnetic resonance spectroscopy (1H NMR) and Fourier transform infrared Spectrometry (FTIR) techniques. The bioester was studied for their physical and main fuel properties including density, specific gravity, kinematic viscosity and high heating value. The results showed that divalent and trivalent metals catalyst could be used as transesterification reaction and give a bioester from natural oil in excelent yields.
