Removal of Silica Bodies on Oil Palm Empty Fruit Bunch Surfaces and Application for Biogas Production

Article Preview

Abstract:

Oil palm empty fruit bunch (OPEFB) in this study was used to remove silica bodies embedded on OPEFB strands. Silica bodies were removed by sonication method at varying sonication temperature of 40, 50 and 60 °C and tested using scanning electron microscopy imaging (SEM), x-ray diffraction (XRD) and applied to an anaerobic digester to quantify biogas production. Sonication was applied using an ultrasonic cleaner, producing 40 kHz sonic wave. This paper intends to utilize and optimize OP-EFB as bio-matrices to enhance biogas production. Results showed that the highest sonication temperature; 60 °C recorded the most perforated holes on SEM image, lowest intensity at 75 CPS for XRD analysis and highest biogas production of 13,919.27 cm3.
