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 Na2SO4
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 gave the mixture with the optimum
quality parameters
of the produced biolubricant. The produced biolubricant had kinematic
viscosities at 100oC
(10.72±0.13 cSt) and 40°C (59.32±0.20 cSt) respectively, a viscosity index of
173±0.10, flash point
of 234±1.13°C, pour point of -31±0.10°C, acid value of 21.04±1.21 mg KOH g-1,
and iodine value
of 1.28±1.40 mg I2 g-1. The produced biolubricant has
quality parameters that are comparable to available
biolubricating oil and was also found within standards for engine oils.
