Characterization of Porosity and Pore Volume in EFB Samples through Physical and Morphological Parameters

Abstract

This study analyses the physical and morphological characteristics of oil palm empty fruit bunch (EFB) fibre samples heated at 150°C. Measurements of parameters such as total volume, solid volume, integral volume, and pore volume were carried out to determine the porosity properties of the samples. Based on the measurement results, the total volume of the sample was recorded at 48.28 cm³, with a solid volume of 10.18 cm³, an integral volume of 16.47 cm³, and a pore volume of 38.09 cm³, resulting in a porosity of 78.90%. The morphological images of the samples support these results by showing significant pore distribution. These findings provide important insights into the structure and potential use of EFB fibres in porous material applications, especially in the context of sustainability and biomass waste utilization. This study also contributes to further understanding of the thermal and physical characteristics of natural materials at high temperatures.
