Comparative study of biodiesel production from different waste oil sources for optimum operation conditions and better engine performance

Biodiesel from waste sources can be considered as the cheapest and most viable fuel alternative to depleting mineral diesel. In this work, biodiesel has been produced different of oil; grilled chicken oil (GCWO) which is animal based source cooking (WCO) vegetable using transesterification method. The impact variables such temperature, time, amount catalyst on conversion yield were investigated. Produced was characterizes ASTM standard methods for property testing determine properties including; kinematic viscosity, specific gravity, flash point, pour cloud point acid number. Engine test conducted at increasing speed constant load evaluate engine performance fuel. results obtained indicate that bio-diesel are greater than oil. Both within specifications D6751. maximum by 97.76% 94.4% suing GWCO WCO respectively optimum operating 600C 3 h reaction 0.4 wt% potassium hydroxide. show similar trends both biodiesels compared diesel in term brake power (BP) consumption (BSFC) with speed. reduction BP found about 19% 2400 rpm a increase BSFC 17% 1800 Accordingly, though comparable performance, presents higher yield.
