The complex processing of industrial waste from various industries was studied, which made it possible to reduce the use of material and energy resources and improve the ecological state of the environment. Chemical, petrochemical, machine-building and food industry wastes were the subject for complex technological processing.
At the same time, a regenerated mixed sorbent (activated carbon + kieselguhr) was used, on the surface of which topochemical transformations of chemicals that were a part of industrial waste took place. The purification of used industrial oil, which was the mineral basis of the developed new C, S, N-containing plastic lubricants, was carried out using a regenerated mixed sorbent. Studies of the tribological properties of new C, S, N-containing plastic lubricants have shown their high anti-wear and heat-resistant properties and the possibility of effective use in highly loaded friction nodes.
