Investigation of Cold Flow Properties of Waste Cooking Biodiesel

Gaurav Dwivedi and Mahendra Pal Sharma
Abstract—Waste cooking biodiesel has high potential as a new and renewable energy source in the future, as a substitution fuel for diesel and can be used in existing diesel engine without modification. But the major quality issue associated with biodiesel to use it as engine fuel is its poor cold flow property. The poor cold flow property results in gum formation and crystallization of fuel particles which lead to solidification of fuel lines and filters and creates the fuel starvation which will ultimately lead to starting problem in engine. The objective of this study to investigate and improve the cold flow properties of waste cooking biodiesel by blending and winterization. Blending was found to be more favourable for improvement in cold flow properties of biodiesel without any effect on yield. The result of experimental investigation shows that cloud point and pour point of waste cooking biodiesel (WCB100) is improved from 14.5⁰C to 9⁰C and 13.7⁰C to 7.5⁰C respectively by three step winterization at the rate of 0.2⁰C at each step. The result also show that 20% ethanol blending lead to drastic improvement in cold flow properties of waste cooking biodiesel and makes it suitable to be used in cold climatic condition.

Index Terms—Biodiesel, cloud point, pour point, blending, ethanol.
