Paper Title: Effect of Portions and Particle Sizes on Energy Content of Oil Palm Fronds
Scope/Category: Materials Science and Technology
Mode of Presenter (Given) : Oral Presenter
Abstract

The caloriļ¬c value (or heating value) is the standard measure of the energy content of
fuel. In order to determine whether certain material can be used for solid fuel, the calorific value
of the material needs to be studied. Hence, the objective of this study is to evaluate the effect of
portions and particle sizes on the calorific value of oil palm fronds. The bomb calorimeter AC
500 was used to measure calorific value of oil palm fronds base on ASTM D58565-07 standard.
The average calorific value of the bottom, middle and top portion of oil palm fronds for smaller
particle size (0.5mm) were 17.12±0.06 MJ/kg, 16.88±0.12 MJ/kg, 16.25±0.08 MJ/kg
respectively. On the other hand, the average calorific value of the same portion of oil palm
fronds for bigger particle size (1.5mm) were 17.77±0.07 MJ/kg, 17.54±0.07 MJ/kg, 17.25±0.03
MJ/kg respectively. The calorific value of oil palm frond has increased from the bottom portion
to the top portion for both small and big particle sizes, and the differentiation is significant
(p<0.01). Based on the results of calorific value, it can be concluded that oil palm fronds has
high calorific value and has the potential to be utilised as solid fuel.
