Ionic Liquids as Green Bio-Lubricant Additives
Puneet Verma, Gaurav Dwivedi, Anoop Kumar Shukla, Anuj Kumar, Arun Kumar Behura
The continuous use of mineral reserves and the extensive concern towards the environment makes it necessary to look for suitable alternatives for petroleum-based lubricants. Growing attention towards a clean environment has led to the introduction of strict emission guidelines for diesel engine vehicles by the government resulting in the use of fuels having minimal sulfur content. This has caused in inferior lubricity characteristics of the fuel. To overcome this problem, interest has shifted towards the development of next generation bio-based lubricants, which can be used as a replacement to lubricants currently used. In an engine, straight vegetable oils (SVOs) offer a good alternative source of lubricants but their stability characteristics (oxidation and thermal storage) and low-temperature performance are not good. Use of polymers is suggested to improve the properties of vegetable oils. In addition to it, the use of biodiesel and longer chain alcohols like n-pentanols and 1-octanol have shown promising results to be a potential alternative to diesel fuel with suitable overall fuel properties.
