The study describes the mechanical behaviour of oil palm empty fruit bunches (EFB)
as a promising product for pyrolysis production. The EFB samples mixture of moisture content
6.3 ± 0.3 (% d.b.) were grouped into different fraction sizes of 10, 20, 40 and 100 mm. The initial
pressing height of each fraction size was measured at 60 mm and compressed at a maximum force
of 4,500 N and speed of 10 mm min-1
to obtain the force-deformation dependencies using the
universal compression machine and pressing vessel of diameter 60 mm with a plunger.
Deformation, deformation energy, volume energy and strain were calculated. While deformation
decreased with fraction sizes, deformation energy increased. The deformation energies at fraction
sizes from 10 mm to 100 mm indicated energy savings of approximately 23%. The optimal
fraction size in relation to energy efficiency was observed at 10 mm. The tangent model
accurately described the mechanical behaviour of the EFB samples mixture. The results provide
useful information for the design of optimal technology for processing EFB for energy purposes.
