ABSTRACT In this study, the regenerations of recovered waste lubricating oil, refined waste lubricating oil, and waste tire recovered pyrolysis oil were studied. The rapid mixing experiments assisted oxidative desulfurization method, combined with high shear force, the phase transfer effects (tetraoctylammonium bromide) and the transition metal catalysis (tungstophosphoric acid, hydrogen peroxide) was executed in wasted oil purification. The solid adsorbents, such as activated carbon, activated clay, activated alumina, were also examined for sulfone removed from the oil to obtain the production of low-sulfur oil, thus, it could achieve the reuse and re-production of clean energy from wasted resources. Oxidation experiments were conducted using high shear force of the time difference, a fixed oil/proportion of hydrogen peroxide, and the dosages of catalysts and surfactants. This research suggests that the oxidation of organic sulfur compounds under the tungstophosphoric acid and tetraoctylammonium bromide increased duration of action by high shear forces, where the oxidation efficiency of the organic sulfur compounds is more increased. With the same amount of oil/hydrogen peroxide (100 mL:100 mL) under different proportions of (tungstophosphoric acid: tetraoctylammonium bromide: duration of action of high shear force), the optimum oxidation parameters are as below: recovered waste lubricating oil is 0.5 g:0.5 g:20 minutes, the refined waste lubricating oil is 0.5 g:0.5 g:20 minutes, waste tire recovered pyrolysis oil is 1 g:1 g:60 minutes. Adsorption experiments using activated carbon, activated alumina, activated clay as the main adsorbents were utilized to examine the Freundish and Langmuir adsorption isotherm model. The experimental data indicated that these three adsorbents are fitted with the Langmuir isotherm model, where the R2 value could reach 0.95. Under the Freundish isotherm, it could be learned that an important parameter n values were all greater than 1. Moreover, this study also indicated that these three adsorbents illustrated good adsorption phenomenon for Sulfone removal. In the dynamic model, the various adsorbents were confirmed with the proposed second-order kinetic adsorption. Considering the temperature effect, these three adsorbents illustrated different adsorption capacity at various temperature, where the minimum adsorption capacity was confirmed at 55?C. |
