【 摘 要 】

This study was carried out to investigate solvent debinding by conducting the extraction process at temperature ranging from 40 to 80 °C within 2 to 8 hours, while keeping the heptane solvent and 12:1 of solvent to feed ratio as constant. The palm kernel loss was evaluated as an indicator of the process's performance. It was also supported by the pore evolution that was observed by Field Emission Scanning Electron Micrograph (FESEM). Results show that both parameter give large effect on the solvent debinding performance. The best immerse temperature and time for extracting maximum palm kernel in heptane solution at S/F ratio of 12:1, without sacrificing the ability of producing free defect metal part were given by 80 °C and 6 hours, respectively.
