Mathematical simulation in enhancing of industrial pyrolysis of hydrocarbon gases and their mixtures with feedback

A general technique was developed for optimal designing pyrolysis with feedback of hydrocarbons C₂-C₄ and their mixtures. Based on this technique, we carried out a study of industrial processes of pyrolysis of propane, ethane, and ethane with the butane-butylene fraction, developed their complete mathematical models that reflected the peculiarities of recycling, and on the basis thereof we defined optimal regimes of governing by these processes that differed significantly from those used in industry. We suggested new ways of governing by all three processes. The use of these ways will allow getting a significant profit by “Ethylene-Polyethylene” plant (Sumgayit). We demonstrated advantages of carrying out pyrolysis of various raw materials with recycling of unreacted raw materials compared with its conducting without recycling.     

Magnetic and catalytic properties of the Ni system on kieselgur

The composition, crystal structure, and character of the magnetic susceptibility of nickel—kieselgur catalyst were studied. The connectivity of the activity and selectivity of the nickel catalyst with local and collective properties of the catalyst surface was established. It was discovered that under the influence of a reaction medium, the magnetic properties of the catalyst differ substantially from its initial properties, due to the formation of clusters on the surface forming an active phase.     

Synthesis and Antimicrobial Properties of Fluorinated 1,2-Aminopropanethiols

Reactions of 1,2-aminopropanethiols with methyl trifluoropyruvate were studied, and the antibacterial and fungicidal activity of the resulting trifluoromethyl derivatives as additives to lubricants was examined.
