dc.description.abstract |
Spent bleaching earth (SBE) is an adsorbent waste of bleaching units in the crude palm oil (CPO) refinery industry. Principally, the SBE can be regenerated and reused as an adsorbent. This research aims to regenerate SBE and determine the influence of particle size variations and temperature in the activation of regenerated spent bleaching earth (RSBE) adsorption on Cu(II) ionic. Particle sizes variations is used (60, 100 and 200 mesh) and the activation temperature (270, 370 and 470oC) to obtained the best conditions for the regeneration process. This regeneration process through the remaining stages of oil extraction using hexane solvent. Furthermore, the material is activated with 3% HCL acid and then reactivated using high temperatures. The result of SBE regeneration (RSBE) tested the adsorption ability in solution ion Cu(II) 20 mg/Liter for 10 hours. Based on the results showed that the best RSBE adsorption power on the condition that the particle sized of 200 mesh and activation temperature 470oC with adsorption 2,002 mg Cu/g RSBE. |
