The article presents the results of research on the preparation of carbon nanofibers from an acetylene-containing gas formed as a result of the disposal of liquid industrial organic waste in the electrocracking process. It is shown that the electrocracking gas can be used for the production of carbo...

In the article a mechanism of pyrocarbon formation on the soot surface by the decomposition of hydrocarbon gases is suggested. The mechanism involves the formation of decomposition products in the gas phase and their adsorption on the active centers of the soot. The defects of a crystal lattice form...

Objectives. A characteristic feature of oil production is an increase in the volume of highviscosity bituminous oil. In Russia, technologies based on the use of water vapor are used for their extraction. The use of such technologies leads to a large amount of water in the product stream from the pro...

The article presents the results of studies on the effect of oil raw material electrocracking duration on the characteristics of the products formed. It is shown that an increase in the duration of the decomposition of the material leads to an increase in the concentration of acetylene in the gas, a...

The research results of the influence of preliminary mechanochemical activation of heavy oil feedstock (oil-fuel, tar) on the output of their coking products are presented. Raw materials were activated by creating a cavitation effect when a hydrocarbon stream passes through a diffuser under a pressu...

Objectives. Recently, there has been a tendency to increase the volume of high-viscosity heavy oils in the total volume of oil produced. The processing of these oils requires new technological approaches. This task is closely related to the need to increase the depth of oil refining. Among the appro...

It is proposed to consider the process of carbon materials oxidative activation from the positions of topochemical reactions involving chemisorption of the activating agent (oxidizer) on the material surface active centers followed by chemical interaction. Such an approach makes it possible to contr...

The formalized model of carbon sorbent synthesis control based on the methodology for functional modeling is constructed. The correlations between the directions of use and the properties of carbon sorbents are revealed. The characteristics that are essential regardless of the direction of use of th...

The possibility of С4+ hydrocarbon synthesis by the hydroolygomerization of acetylene contained in the gas obtained by electrocracking of organic raw materials is shown.

The article gives a brief overview of studies on the decomposition of hydrocarbons in electrical discharges. The authors suggest using this process for the possible utilization of liquid organic waste of chemical and petrochemical industries, which gives a wide range of valuable products.

The article suggests a mechanism of pyrocarbon formation on the soot surface and explains the reason of specific surface polyextremity changing. It is possible only due to heterogeneity of pyrocarbon deposition process. It is assumed that hydrocarbon products adsorption from a gas phase takes place...

Objectives. The reduction of the anthropogenic burden on the environment is generally associated with the transition to alternative energy sources. However, some of these have only regional significance, while the effectiveness of others remains doubtful. On this point, innovative processes aimed at...
