Scientific direction:

Zeolite catalysts and acid-basic zeolite catalysis of complicated hydrocarbon transformations: synthesis of zeolite acid catalysts; investigation of their adsorption and acid properties; testing in the most significant carbonium ion reactions of hydrocarbon transformations; studying the carbonium ion reaction proceeding consistent patterns as well as pilot studying the efficiency of catalysts synthesized; investigating the mechanisms of carbonium ion reactions of hydrocarbon transformations; developing the catalyst technologies and corresponding catalytic processes.

Perspective researches

Zeolite catalyst of mineral basis and heterogeneous-catalytic isobutane with butenes alkylation under conditions close to the critical ones with the purpose of utilizing the catalytic cracking butane-butene cut towards the alkylate - high octane gasoline component. Catalyst on the basis of modified with transition metals mordenite-cliniptilolite rock of Ukrainian deposits and heterogeneous-catalytic isomerization of light-gasoline-cut linear paraffins towards isomerizate - high octane gasoline component (together with L.V. Pisarghevsky's Institute of Physical Chemistry of Ukrainian National Academy of Sciences). Optimization of acid spectra of catalysts for different carbonium ion transformations. Investigating the deactivation of catalysts in the main carbonium ion reactions with the simultaneous studying the character of coke formed.

Additional information

Laboratory scale technology of obtaining the micro spherical zeolite-containing fluid cracking catalyst on the basis of Ukrainian kaolin has been developed. Together with L.V. Pisarghevsky's Institute of Physical Chemistry of Ukrainian National Academy of Sciences the laboratory scale technology of preparing the catalyst on the basis of Ukrainian mordenite-clinoptilolite rocks for linear paraffin isomerization has been developed. Together with the Ukrainian Petroleum Processing Industry Research Institute "MASMA" zeolite catalyst as well as the technology of benzene (toluene) with C8-C24 alkylation for the purpose of obtaining the alkylbenzenes as the raw materials for producing the surfactants and mineral oil additivies have been developed. The thermodynamic treating of hysteresis phenomena in heterogeneous systems Asolid + Bgas(vapor) = ABsolid has been given. The phenomenon of oscillatory adsorption on zeolites has been observed. Its nature in the terms of irreversible thermodynamics has been interpreted. The oscillatory proceeding of carbonium ion reactions of hydrocarbon transformations has been revealed. It is treated on the basis of oscillatory adsorption. The concept of decisive role of primary carbocations, stabilized with negative charged positions of zeolite structure, on the starting and finishing steps of carbonium ion transformations whereas the secondary and tertiary carbocations are of decisive importance in intramolecular rearrangement has been proposed. Direct dehydrocyclization of linear hexane to benzene over nickel-containing acid catalyst has been realized. The tricentres isomerization and aromatization model has been proposed, according to which the catalyst active centre includes Broensted and Lewis acid sites as well as the hydrogenating-dehydrogenating site.
