Extraction-Adsorption Methods for Regenerating Spent Oils

详细

An adsorbent obtained by applying orthophosphoric acid to a peat surface was investigated during the refining of used mineral lubricating oil. The degree of regeneration (clarification) of the used oil depended on the adsorbent modification method, i.e., the acid/peat ratio, adsorbent/oil residue mass ratio, and mixing time of the phases.
