520 3 _aSpent bleaching earth (SBE) is clay which in its virgin state has ability to adsorb coloring matter and remove organics. The disposal of SBE brings environmental problem in Malaysia due to its high oil content. Large volume of used lubricant oil is produced each year. Waste oil regeneration process is carried out to reduce the amount of waste oil disposal which may leads to environmental damage. In this study, regenerated SBE was used as an adsorbent for lubricant base oil decolorization. This study was conducted by varying the temperature, SBE dosage and agitation time to investigate the effectiveness of SBE in adsorption process and determine the physical properties of treated oil as well. The oil properties studied were color, flash point, pour point, water content and viscosity. Copper corrosion test was done for treated oil oxidation stability testing. Prior to experiment work, the Design of Expert Software was employed to aid the analysis of experimental data collected. The software is capable to design the research experiment with minimal statistical error. From the analysis and results, it showed that 140°C operating temperature, 5g SBE usage and 120 min agitation time provided the most suitable condition to obtain desirable oil. The adsorption process follow Langmuir isotherm. As conclusion, even though SBE is not effective in decolorization process, it has potential in removing water and contaminants in used oil.
