The study presents the investigation results of the new polyfunctional catalysts for the synthesis of commercially important hydrocarbons (ethylene, propylene, 1,3-butadiene, hexane isomers) and oxygenates (1-butanol, 2-ethyl-1-hexanol) from С1,2,4-bio alcohols via consequent transformations. Scientific approaches to the development of highly active catalysts for these processes have been developed. It allows establishing the production of components of motor and rocket fuels, polymeric materials from renewable feed in Ukraine.

The new efficient Zn(Ag)/Mg(Zr, La)-Si oxide and zeolite-containing (BEA) catalysts for 1,3-butadiene synthesis from renewable feed (bioethanol) are developed.

The process of gas-phase condensation of 1-butanol into 2-ethyl-1-hexanol is implemented for the first time in a flow regime using Mg-Al-oxide catalysts. The principal possibility of the direct derivation of 2-ethyl-1-hexanol from bioethanol at atmospheric pressure in a flow reactor is shown.

A series of new catalysts based on MFI zeolite and alumina demonstrating high activity in the process of ethylene and propylene synthesis from methanol is developed. The catalysts exhibit higher productivity and lifetime compared to existing catalysts via regulating the strength of the surface acid sites and anomalously fast reagent transport in the catalyst particle.

Ni-containing polyfunctional catalysts based on microporous zeolites of MOR and MFI morphology are developed for n-hexane isomerization, which allows the derivation of highly-octane additives of motor fuels. The catalysts demonstrate the efficiency comparable with Pd-containing catalysts at lower temperatures.

Number of publications: 43 scientific papers (31 is published in English language journals with impact factor), 33 abstracts presented at domestic and international conferences. The total number of citations/h-index of the study according to the databases is: Web of Science – 143/7, Scopus – 168/9, Google Scholar – 202/9. 4 Ukrainian patents are obtained.
