Abstract

The rising concern over the existing lubricants have driven the need for biolubricants, extensively anticipated as the most suitable and sustainable lubricating oils. In this study, a biolubricant was synthesized from Marula kernel oil (MKO) via a two-step transesterification process using trimethylolpropane (TMP), in the presence of potassium hydroxide as catalyst. The kernel oil was first extracted then characterized using standard laboratory techniques before being chemically modified to produce Marula kernel oil biolubricant (MKOB). The synthesized biolubricant and its blends with mineral oil were analyzed for their lubricity properties. The results obtained shows that the kinematic viscosity at 40 ℃ and 100 ℃ were (9.3 cSt) and (3.3 cSt) respectively, viscosity index was quite high with a value of (207) while the flash and pour point value were (215 ℃) and (11 ℃) respectively. The lubricity properties of the synthesized biolubricant were comparable with those of the mineral oil (SAE 20) and are also within the range of recognized testing standards such as viscosity grade 32 (ISO-VG-32). From the results obtained, it can be deduced that the blends of the MKO biolubricant with mineral oil (SAE20) in various proportions were proved to have the quality lubrication properties, making them a suitable alternative to mineral oil based lubricant, and could therefore be used to reduce the consumption of mineral oil, which will in turn help to achieve a greener future.
