Evaluation and characterization of lithium grease from Palm kernel oil for automobiles and industrial machinery

Grease is made up of a lubricant (typically petroleum oil) and a thickener (soap). The study focus on the production and characterization of grease for automobile and industrial machinery. The practicality and application of the technique were examined in order to decide whether the lithium grease produced from palm kernel oil might be used as an environmental friendly alternative to conventional grease. The aforementioned objective was achieved by mechanically extracting oil from palm kernel nuts. Lithium grease was produced through the saponification of lithium oxide with palm kernel oil. The lithium grease melting and drop points, flash point, and ash content were discussed. According to the study's findings, the lithium grease produced results that were acceptable and in accordance with ASTM standards, with the exception of its ash content, which will cause the grease to break off under pressure.
