Analysis of Properties of Biolubricant Obtained from Blends of Used Palm Oil | Chapter 10 | Theory and Applications of Chemistry Vol. 2
Vegetable oils are providing alternatives as renewable sources for the production of ecofriendly biolubricants due to increasing environmental challenges, depleting mineral energy reserves, and cost of production from fossil sources. This study evaluates the quality parameters of biolubricant obtained from used palm oil (UPO). The crude UPO was filtered, centrifuged at 500 rpm, and dried over Na 2 SO 4 crystals overnight. The quality parameters of the pretreated UPO (PUPO) were analysed to authenticate its potential for the production of multigrade lubricating oils. Kinematic viscosities at 100°C (8.26±0.03 cSt) and 40°C (36.98±0.01 cSt) were determined according to ASTMD-446 method, while the viscosity index (208±0.11) was determined according to ASTMD-2270 method. A design of experiment (Mixture Design Method using Minitab 17) was used to determine the proportion of PUPO (68.75%), SN 500 (23.75%), and additives (7.50%) that gav...
