Research object – nanocomposite catalytic systems based on alumina, zeolites, and carbon nanomaterials. Purpose of work – to verify the influence of physicochemical characteristics on the catalytic properties of nanocarbon, zeolite, and nanocarbon-containing catalysts in the processes of methanol conversion, hydrogenation and dehydrogenation of organic compounds. The aim of the work is to develop nanocarbon-containing catalysts for methanol conversion and hydrogenation/dehydrogenation processes, which are characterized by increased productivity and implementation of abnormally fast transport of reagents in the catalyst grain. Research methods – synthesis of carbon nanomaterials according to previously developed methods. Researching catalytic activity in stationary and nonstationary modes. Carrying out quantum chemical calculations using the US GAMESS module. Results and novelty: As a result of the implementation of the project stage, zeolite-containing nanocomposites based on carbon nanotubes with incorporated nanoparticles of iron, nickel and platinum were synthesized, which were characterized and their catalytic properties were investigated in the reactions of hydrogenation of squalene, dicyclopentadiene, dibenzyltoluene, CO2, and dehydrogenation of perhydrodibenzyltoluene. The reaction mechanism of the conversion of methanol to formaldehyde in the presence of nanocomposites based on carbon nanotubes was established, kinetic models were developed and kinetic parameters of the process were calculated. Using the methods of quantum mechanics, the energy profile of hydrogen migration from metal nanoparticles to carbon nanomaterial and its interaction with organic substrates was established. A macrokinetic equation was developed, which takes into account the presence of anomalous diffusion in the catalyst grain, and the peculiarities of the macrokinetics of the conversion of methanol into dimeth Product Description popup.authors Bychko Igor Didenko Olga Zhokh Olexiy Karpenko Oksana Trypolskyi Andriy popup.nrat_date 2023-11-30 Close
