Electrochemical regeneration of oxygencontaining compounds in the extracts of used oils
Journal Title: Восточно-Европейский журнал передовых технологий - Year 2018, Vol 1, Issue 6
Abstract
<p>Growth in the volumes of oils applied for various purposes, including motor oils, results in the formation of large quantities of toxic waste – used oils. At the same time, they are a valuable raw material for the production of fresh oils by their regeneration though existing techniques have a number of shortcomings, the main of which is the formation of new waste that is difficult to dispose of.</p><p>It is shown that the extraction of used oils by an alkaline aqueous-alcohol solution enables an almost complete removal of oxygen-containing compounds, as evidenced by the reduced acid number, from 1.76 mg KOH/g of oil to 0 mg KOH/g of oil. This results in a significant decrease in corrosion aggressiveness of the medium.</p><p>The results of research into electrochemical processes in model solutions of ketones, aldehydes and carboxylic acids revealed the possibility to transform their products on electrodes into non-toxic useful products – carbohydrate products.</p><p>The results of research into electrochemical processes in model solutions of oxygen-containing compounds and extracts of used oils at anodic potentials of 2.4 V demonstrated the possibility of their transformation on electrodes into useful carbohydrate products. This would contribute to an increase in the output of regenerated oil, prevents the formation of toxic waste.</p>
