3. 1.0 INTRODUCTION
3
An overview about the synthesis of metal supported
on char as the green catalysts.
By using carboxylation of glycerol technique, the
glycerol carbonate can be produced.
There are different types of char that can be used
which are rice husk char, plastic char, empty fruit
bunch char and palm kernel shell char.

4. 2.0 PROBLEM STATEMENTS
4
For every 10kg of biodiesel production, 1kg of glycerol will be produced.
(Razali et al., 2019)
A massive amount of waste from the palm oil extraction process can exceed 70–80 million tons per year.
(Roslan et al, 2014).
Disposal of glycerol waste cost an arm and leg in order to save environment.
Therefore, there is an initiative to utilise glycerol and convert it to the good products value which is glycerol
carbonate that has a high potential in economic and environmental concerns.

MATERIALS:
Palm Kernel Shell (PKS)
PREPARATION OF CATALYST:
- The char was taken from Pyrolysis Technology Research Group University
Malaysia Terengganu (UMT).
- Prepared via impregnation method.
CHARACTERIZATION OF CATALYST:
Characterized the morphology by:
- Scanning Electron Method (SEM)
- Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR)
- X-ray Diffraction (XRD)

CATALYTIC REACTION:
The experiment will study the effect of these parameters towards the
glycerol carbonate formation which are:
- Reaction temperature
- Catalyst loading
- Reaction time
- Pressure
LIQUID SAMPLE ANALYSIS:
- Fourier Transform Infrared (FTIR) spectroscopy is used to
see the surface functionality of liquid samples.
- Gas chromatography - mass spectrometry is used to
identify the composition of liquid products collected.
% conversion = 100 × (
moles of glycerol consumed
moles of glycerol introduced
) %
selectivity = 100 × (
moles of glycerol carbonate formed

)
The yield of glycerol carbonate from glycerol is the product of
conversion and selectivity (Razali, Conte et al. 2019)

 As a conclusion, palm kernel shell has successfully synthesized glycerol carbonate from the
carboxylation of glycerol.
 Copper oxide supported on palm kernel shell increased the yield of the glycerol carbonate.
 Acetonitrile has been used as dehydrating agents to shift the equilibrium sides towards the
product side.
 This study gives the view of carboxylation of glycerol and suggests the possibility of using palm
kernel shell char and metal supported on char as the heterogeneous catalyst.
