| الوصف: | Oil palm empty fruit bunch (OPEFB) is a by-product of palm oil processing that is considered solid waste. It is produced in a large amount, counting up to 23% of the fresh fruit bunch (FFB). The ash content in OPEFB comprises a potassium compound. Potassium can be potentially recovered as potassium carbonate by extracting it with water. This study aims to investigate a method to recover potassium from OPEFB ash as potassium carbonate for further processing into potassium-based fertilizer. This research consists of pyrolysis process of OPEFB into char, then the char is analyzed by TGA in order to determine the ashing temperature. The temperature of 250°C, 400°C and 550°C are chosen for the ashing (combustion) process. The resulted ash is then extracted by water with the Feed to Solvent ratio of 1:4, 1:5, and 1:6, respectively. From the AAS analysis result, the highest potassium concentration is obtained at temperature of 400°C with F:S ratio = 1:6, with the potassium concentration of 49,94 %-w/w. This value is suitable for liquid fertilizer. |
