Abstract

This study research focused on the properties of raw and torrified pellet from EFB by
varying different parameters, including energy consumption, moisture adsorption, meyer
hardness test and pellet density. To save storage space and transport costs, it can be
compressed into fuel pellets of high physical and energetic density. The pelletizing
properties were determined using single pellet press and pellet stability was determined by
compression testing. Pelletization of raw and torrified empty fruit bunch (EFB) from
compression single pellet press (SPP) was investigated to quantify the energy consumption
and pellet properties, including moisture adsorption, pellet density and Meyer hardness .
Energy consumption for torrified EFB pellet were significantly higher than those for raw
EFB pellet, while the moisture adsorption rate of torrified EFB pellets increased with
increasing the severity of torrefaction. Decomposition of hemicellulose and lignin reduced
the plasticity of raw sample contributes to increase energy consumption during compression.
The hardness of pellet made at same pelleting condition decreased with the increasing of
size of sample. The densities of torrified EFB pellets were higher than raw EFB pellet due to
the loss of chemically bonded water and low melting point compounds during torrefaction
which act as binding agent. The properties of pellets were affected by the removal of most
low melting or softening point components.
