Abstract:

In the present work the application of novel technique was highlighted for reduction of adsorbent content in recovery process of waste motor oil by effective acidification. The effects of acidification factors such as acid proportions, adsorbent dose, powder/acid ratio and residence time were analyzed on removal of contaminates from waste oil. Acetic, hydrochloric and sulfuric acids were mixed according to the statistical mixture design algorithm to prepare acidification agents. The dry original clay was submitted into the prepared acidic solutions. The designed instrumental setup allowed the preparation of nano-porous powders where the controlled factors were residence time. The distillation of waste oil was carried out in the industrial scale. The significance of independent variables and their interactions were tested by blending the obtained powders with distillated oil and then the adsorption was evaluated, spectrophotometrically. The experimental results revealed the region in which the optimum regeneration of waste oil is obtainable. In order to well understand the role of nano-structured material on regeneration, the adsorbents were characterized through X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller surface area measurement and scanning electron microscopy. The employment of acetic acid in combination with sulfuric acid plays an effective role in development porous structure and improvement of contaminant adsorption. The powder produced in optimum condition contains nano-pores with diameter about 11 nm. The employment of this technique provides a potential for reduction of adsorbent content, 33.3 wt%. Finally, it was demonstrated that the efficiency of prepared adsorbent supports further development for commercial application purpose.
