Tribological Investigations of Waste Cooking Palm Oil Using Them for Production of Lubricants

The purpose of this research was the evaluation the lubricating properties of waste cooking oil (WCO) of palm oil and its mixtures with waste cooking oil of rapeseed and sunflower oils. The research results show that both palm oil WCO alone and its mixtures with rapeseed and sunflower oils have not lost their lubricating properties during cooking, especially when using the functional lubrication additives. These additives can reduce the friction and wear of specimens not only with rapeseed and sunflower oils, but also using pure WCO. Estimating the possibility of producing plastic lubricants from palm oil WCO it has been established that it is possible to obtain lubricating greases with a dropping temperature of operation conditions.
