Laboratory of Microwave Activation of Catalytic Processes

Scientific results:

Within the framework of the project, energy-efficient microwave processes have been developed for the synthesis of various nanocatalysts with deposited metal or oxide nanoparticles and in-situ activation of catalytic processes under the action of microwave radiation, including CO2 utilization processes, deep processing of hydrocarbon and renewable raw materials, hydrogen energy processes (hydrogen storage). Bimetallic nanoparticles (Fe, Cu, Ni, Co, Pt, Pd, Au, Rh, Ag, Ru) on porous supports, oxides with a perovskite structure were obtained, their structure was studied by various physico-chemical methods and their activity in a number of reactions such as hydrocracking, hydrogenation of aromatic and acetylene hydrocarbons, hydrogenation of nitriles and nitro groups, ring opening of polycyclic compounds, hydrogenolysis, dehydrogenation of naphthenes, partial oxidation of methane into synthesis gas and ethylene, partial oxidation of ethane and propane into olefins under the action of O₂ and CO₂, complete oxidation of volatile organic compounds (toluene, dichloromethane, ethanol as model compounds), production and cyclic use of substrates for hydrogen storage in liquid organic carriers (polycyclic compounds), hydrogenation of CO₂ into CO, as well as synthesis of olefins, alcohols and hydrocarbons from cheap industrial (alkanes, asphaltenes) and vegetable (oils, polyols, 5-hydroxymethylfurfural) raw materials and biomass, and hydrogenation of CO₂ into olefins. The proposed approach is based on the use of microwave activation of catalysts for the decomposition of precursors, preparation of catalysts, or for in-situ activation of catalysts directly during catalytic processes. Both approaches make it possible to increase the activity, selectivity and stability of the catalyst by reducing the contribution of side reactions, destruction, and sintering of the active component. At the same time, a reduction in energy consumption for the synthesis of nanomaterials and the implementation of catalytic processes is achieved by reducing the synthesis temperature of nanocatalysts and/or the temperature of the catalytic process and reducing the regeneration stage and due to the non-thermal effects of microwave activation of catalysts, especially in the presence of hydrogen under conditions of dissociative hydrogen adsorption.
