It includes studying catalytic processes such as the dry reforming of methane/biogas into synthesis gas (H2/CO) and the CO2-mediated oxidative dehydrogenation of C3, C4 alkanes to produce propene, butenes, and buta-1,3-diene. The main focus is on constructing metal-oxide and zeolite catalysts by tuning their functional properties based on correlation studies between catalyst composition (active components, carriers, dopants), their physical and chemical characteristics, and catalytic behavior. It was found that during the dry reforming of methane on Ni-Al2O3/cordierite catalysts modified with rare earth oxides (CeO2, La2O3), reagents activate at different surface sites: CH4 on Ni0, and CO2 on MeOx (Me = La, Ce). This prevents competition for active sites and promotes stable conversion. For the CO2-mediated oxidative dehydrogenation of propane, acid-base properties of the surface of M-BEA (M = Ga(Ta, Nb), Zn(Y), Cr/Zn) bifunctional catalysts directly influence activity, propene selectivity, and operation stability, as well as the reaction progress through direct dehydrogenation and the reverse water-gas shift reaction. Catalyst efficiency hinges on balanced surface acid-base characteristics. For the CO2-mediated oxidative dehydrogenation of n-butane, specialized Ni(Fe,Cr,Ce)-(Bi,Mo)/Al2O3 metal-oxide catalysts have been developed. Weak and medium-strength Lewis acid-base pairs involving Ni and Mo facilitate the dehydrogenation process. Over Ni active sites, n-butane is converted into C4 alkenes and alkadienes, while Mo promotes hydrogen removal from the alkene molecules. Product Description popup.authors Svitlana M. Orlyk Olha V.
