Biodiesel Synthesis from Cameroon Palm Kernel Seed Oil | Chapter 1 | Current Strategies in Biotechnology and Bioresource Technology Vol. 1
Aims: This study was aimed at synthesizing and characterizing
a biodiesel from Cameroon palm kernel oilseed. Study Design: Synthesis was
carried out on purified kernel oil by trans-esterification using methanol in
basic medium. Place and Duration of Study: Laboratory work was effectively
carried out in the Department of Chemical Engineering (Ahmadu Bello University,
Nigeria) and at the Kaduna Refinery and Petrochemical Company (K.R.P.C),
Nigeria, in the early part of the year 2017. Methodology: Oil was extracted
from Cameroon palm kernel seeds, which constitutes an agricultural industrial
waste, by mechanical expression, was purified and analysed. Palm kernel oil
(PKO) biodiesel was synthesised by trans-esterification in methanol with
potassium hydroxide (KOH) as a base catalyst at the mass ratio PKO to methanol
to KOH of 100:20:1. Results: The yield of optimised synthesis of biodiesel was
97%, with a useful by-product (glycerol) which has potential pharmaceutical,
cosmetic and engineering applications. PKO biodiesel was analysed using UV and
IR spectroscopy and gas chromatography-mass spectrometry (GC-MS). Biodiesel had
the following physical characteristics: specific gravity 0.884 g/mL, ASTM
colour 1.5, viscosity at 40ºC 4.9080 cSt, viscosity at 100ºC 1.7914 cSt, cloud
point 17ºC, pour point 0ºC, flash point 50ºC, aniline point 90ºF, cetane number
28, and diesel index 25. The following chemical parameters were obtained for
the synthesized PKO Biodiesel: sulphur content 0.0328% w/v, acid value 0.4488
mg KOH/g, free fatty acid (FFA) content 0.2244 mg KOH/g, iodine value 7.36 mg
I2/g, saponification value 168.30 mg KOH/g, ester value 154.84 mg KOH/g,
hydroxyl value 51.89 mg OH/g and peroxide value 3.20 meq/kg. Conclusion: These
results of physical and chemical characterisation of PKO biodiesel fell
