Abstract

Abstract: Waste cooking oil (WCO) can be used as a potential feedstocks for biodiesel production owing to its availability and cheap price. The main obstacle of using waste cooking biodiesel (WCB) as a fuel in engine is its cold flow properties (CFP) such as cloud point (CP) and pour point (PP). The CFP of biodiesel results in gum formation which is further leads to solidification of fuel, fuel line and filter which ultimately resulted in starting problem of engine. The CFP can be improved by adding cold flow improvers, blending and winterization. The present study investigates and improves the CFP of WCB using blending, and winterization. The result of the present study shows that CP and PP are improved from 14.1 to 8.6 °C and 10.3 to 2.1 °C respectively by using three steps winterization. The result also concluded that drastic improvement in CFP of WCB by 20% ethanol blending. It is found that ethanol as cold flow improver plays major role in enhancement of CFP of WCB as it improve both by 8 °C. The result of investigation recommends the use of WCBE20 blend of WCB with ethanol for engine operation under cold climatic condition without any fuel quality problem. Out of various methods for improving cold flow properties addition of cold flow improver is best method to achieve the desired values of cold flow properties for biodiesel.
