The work carried out systematic research to create a technology for restoring the original properties of used oils. Adsorption purification of waste oils using the bentonite-vermiculite method was carried out. based on the use of the ability to retain oily contaminants penetrating through the outer surface and internal capillaries - the pores of the sorbent granules.
