Optimization of Biodiesel Production from Goat Tallow Using Alkaline Catalysts and Combining them with Diesel

In this research biodiesel is produced from goat tallow in the presence of homogenous catalysts such as KOH and NaOH using trans-esterification process. For this purpose, effect of several parameters such as temperature, reaction time, methanol to oil ratio, type and concentration of a catalyst has been investigated. The results showed that the maximum biodiesel yield (96 and 98 %) was obtained using NaOH and KOH, respectively, and optimal conditions were determined.
