A Comprehensive Review on Palm Oil and the Challenges using Vegetable Oil as Lubricant Base-Stock
Keywords:vegetable oil, palm oil, renewable energy
Many researchers have discovered that palm oil and most of the vegetable oils have a potential to be the main sources for environmentally favourable lubricant, due to its properties that showed excellent lubrication performance, biodegradability and also renewability. Poor low-temperature behaviour, low oxidation and thermal stability, and narrow range of available stabilities will create a boundaries of bio-lubricant to be apply as a good lubricant. Bio-lubricant can be used in many types of applications such as automotive transmission fluids, metal working fluids, cold rolling oils, fire resistant hydraulic fluids, industrial gear oils, neat cutting oils and automotive gear lubricants. This review will address the challenge of using vegetable oil as a lubricant base-stock and also the palm oil as a potential lubricant. There are many advantages and disadvantages using vegetable oil as a lubricant that will be discussed in this paper. The aim of this paper also to study the past, current and future of vegetable oil and the use of palm oil as a lubricant.
