Effect of synthetic cold flow additives on properties of biodiesel and biodiesel-diesel blends: A mini-review

Abstract

The demand for an alternative fuel to control fossil fuels is increasing, and biodiesel can play a crucial role in combatting the problems. Biodiesel that has been produced through various feedstocks employing different processes is a renewable and eco-friendly fuel. However, the generation of fewer emissions than fossil fuel makes it one favourable choice, but its marketability is still restricted due to poor cold flow behaviour and oxidation stability. In this review, we have focused on the cold flow problem of biodiesel which hampers functioning of diesel engines. This review particularly explores the types of synthetic additives, their mechanism of action, and their application in biodiesel-diesel blends in the last seven years.
