dc.description.abstractThis study aims to reclaim the base oil component of used lubricating oils for reuse. The base oil reclamation strategies were carried out in a three-stage process namely, physical, chemical and adsorptive processes. The physical processes adopted include sedimentation and natural settling by gravity, magnetization, and filtration for the removal of metallic and non-metallic related particles.The chemical process included acidification with H2SO4, alkalinization with NaOH, solvent extraction and hydro-treatment. The adsorption process used a combination of bentonite powder and silica gel / activated carbon adsorbent in specific proportions.Comparison of lubricating properties of all the samples indicated that sample 6, which passed through the adsorption process in addition gave the best conditions for the base oil reclamation process.Of all the lubricating properties investigated, only the flash point was not significantly reclaimed in comparison with others. The infra-red spectroscopy of the samples was also performed and indicated that peak infra-red spectroscopy values occurred at approximately equal wave numbers of 1457.76, 2852.28 and 2921.01cm-1.en_US
