This research study aims to investigate and design Biodiesel washing machine of washing the catalyst. Soap and alcohol done and contaminants from the biodiesel.
The factors to washing biodiesel there are 3 parts. 1). The water content of biodiesel 0.8: 1.0, 1.25: 1.0 and 2.5: 1.0, 2) flow rates on the 2 , 3 and 4 L/min. 3) The time it takes to wash the biodiesel at 0.5. 1 and 2, respectively
