The utilization of liquid fuels such as biodiesel produced from used frying oil by transesterification process is represents one of the most promising optional sources for the use of conventional fossil fuels. This study describes the characterization and optimization parameters of used frying oil to biodiesel. The process variables were employed i.e., methanol to oil molar ratio (3:1- 9:1), catalyst (KOH, NaOH, CH3OK, and CH3ONa), catalyst (0.5, 1.0 and 1.5 wt %), temperature (50, 60, and 70°C), time (30, 60, 90 and 120 min) and alcohols (CH3OH, C2H5OH, and C3H7OH) used this experiments. The optimized biodiesel parameters were: KOH Catalyst, 6:1 molar ratio, 1.0 wt % of catalyst concentration, 60°C temperature, and 120 min reaction time. The GC Techniques were used to identify the fatty acid profile of the used frying oil and biodiesel and FTIR Technique is used to identify the peaks formed in final biodiesel product.
