Abstract. The article presents the results of the process of regeneration of used Shell Mysella-40 motor oil used at Modular Power Plants operating in a number of regions of the republic. Samples of oil operated for 2000, 4000 and 6000 hours were examined. A number of quality indicators, such as viscosity index, antioxidant stability, density, etc., provided the basis for further research on the regeneration of a Mysella-40 motor oil sample that has worked for 6000 hours.
The regeneration process consisted in the release of oil from acid sludge and mechanical impurities by the acid-contact method, followed by purification of the product from residual resinous substances using bentonite (bleaching clay) and neutralization of acidic products with the M-1 adsorbent. The gas bubbles formed in the oil during the regeneration process and their further transformation into steam flows occurred by cavitation.
Based on the quality indicators of the resulting regeneration product, it was established that it can be used as a base oil when creating lubricant compositions for diesel engines for various purposes.
On the basis of the regeneration product and the corresponding additives, new lubricating compositions of motor oils were created: for diesel locomotive and industrial diesel engines of the M-14Г2 SAE 40 API CC brand, for forced autotractor diesel engines operating with supercharging and naturally aspirated, of the M-10Г2 SAE 30 API CC brand, for two- and four-stroke high-speed medium-loaded transport diesel engines with a tougher temperature regime of the brand М-16ИХП-3 SAE 40 API CB The compliance of the physicochemical and operational properties of new lubricating compositions with their commercial oils was determined.
