Abstract

Palm kernel shell is solid waste produced from the processing of crude palm oil (CPO). In this context, phosphoric acid (H3PO4) serves as an essential activator for producing an adsorbent with maximum micropore under operating conditions at a temperature of <450oC. Therefore, this study aimed to determine the optimal adsorbent condition of the palm kernel shell using H3PO4activator. The production process was optimized using Response Surface Methodology (RSM) and Central Composite Design (CCD) methods with activator concentration variations of 4%, 5%, and 6%, at activation times of 23 hours, 24 hours, and 25 hours, respectively. The quality of the adsorbent produced fulfilled SNI standard 06-3730-1995, characterized by water content of 1.001%, ash content of 5.767%, missing substance level of 18.932%, and fixed carbon content of 75.301%. Furthermore, this work effectively optimized the RSM and CCD adsorbent production process, achieving 4.785% variation in activator concentration and 24.679 hours activation time.

Abstract

Most waste from palm oil processing can be repurposed, such as using palm fibre waste to create activated charcoal. This study aimed to assess the effectiveness of activated charcoal, produced by activating palm fibre with H₃PO₄, in removing silica from boiler output water. The production process involved pyrolysis at 200ºC for 2.5 hours. A completely randomized design was employed to test the effects of different H₃PO₄ concentration (with 1 to 2 M) and reaction times (30, 60, and 90 min). Results revealed that the moisture content of the activated charcoal ranged from 1.96% to 2.42%, ash content from 9.82% to 21.63%, and iodine adsorption from 366.43 to 457.87 mg/g. The highest silica adsorption capacity (3.5 g/g) was achieved with 2 M H₃PO₄ for 90 min. This indicates that palm fibre-derived activated charcoal is effective for silica removal, highlighting it is potential for enhancing environmental sustainability in industrial sector.
