Carbonization of heavy residues of different origin

Investigation of the optimization of the feedstock composition on delayed coking units (UZK 21-10/3M) at the Angarsk Petrochemical Company using the introduction of different heavy oil residues and by-products of petroleum chemistry was carried out. The optimal feedstock composition was determined on the model bench-scale delayed coking units. The samples of petroleum cokes obtained from the feedstock of different compositions were analyzed for the sulfur content, and their microstructure was thoroughly studied in detail. The obtained array of experimental data showed that the optimized coking feedstock composition holds promise from the viewpoint of both the improvement of the quality of the petroleum coke and an increase in its production rate.     

Enhancement of the efficiency of the process of mild catalytic oxidation of methane

A model of in-series connected reactors for the mild oxidation of natural gas that makes it possible to use a high selectivity of catalysts for a higher conversion of the gas to the desired product is proposed.     

Effect of local oxygen therapy on reparative regeneration of the bone

An apocrine hidrocystoma of the shoulder of a 59-year-old woman is, to our knowledge, only the third reported case that arose outside of the head and genitalia. Its origin was nonetheless consistent with the distribution of apocrine glands in adults.
