ON THE EFFECT OF ZEOLITE TYPE ON THE FORMATION OF PD-CO NANOPARTICLES AND THEIR CATALYTIC PROPERTIES IN SELECTIVE HYDROGENATION OF FURFURAL

(STEF92 Technology, 2026, Valentina Matveeva, Linda Nikoshvili, Daniil Lisichkin, Boris Tikhonov, Maksim Grigoriev)

Selective hydrogenation of biomass-derived molecules catalyzed by metals is in high demand, but is challenging due to complex reaction pathways. Furfural (FF) is a highly effective chemical produced by processing agricultural and woodworking waste and used to produce furfuryl alcohol (FA), furan, 2-methylfuran, tetrahydrofurfuryl alcohol, etc. Furfuryl alcohol is used in the production of acid-resistant polymer concrete, fiberglass, paint and varnish materials (as a film-forming agent), as well as to create variou...

STUDY OF THE KINETIC OF BIOCATALYTIC REACTIONS USING MAGNETICALLY SEPARABLE OXIDOREDUCTASES

(STEF92 Technology, 2026, Olga Grebennikova, Aleksandrina Sulman, Alyona Sokolova, Boris Tikhonov, Valentina Matveeva)

Oxidoreductase enzymes play a key role in modern biotechnology due to their high specificity and ability to catalyze redox processes under mild conditions. They are used in environmental monitoring, biosensor development, and fine organic synthesis. However, their practical use in their native form is limited by their low stability, sensitivity to environmental changes, and the inability to re-extract from the reaction mixture. Immobilizing enzymes on various carriers can solve these problems. Magnetic nanoparticl...

STUDY OF THERMAL AND CHEMICAL STABILITY OF AMORPHOUS AROMATIC POLYMERS ?? SUPPORTS FOR PALLADIUM CATALYSTS

(STEF92 Technology, 2026, Linda Nikoshvili, Elena Bakhvalova, Valentina Matveeva)

Show more

Amorphous aromatic polymers synthesized by the knitting method are promising supports in catalysis, since they have high porosity (up to about 1000 m2/g) and can be synthesized by the simple one-step procedure using a variety of available aromatic monomers [1-4]. In catalysis, the stability of active phase is typically discussed, while the stability of polymeric support remains outside the scope. At the same time, many reactions require high temperature or application of strong acids or bases. In this work, a seri...

THE USE OF RU/MN 100 FOR MONOSACCHARIDE HYDROGENATION

(STEF92 Technology, 2017-06-20, Esther Sulman, Maxim Grigore, Galina Demidenko, Irina Shkileva, Valentina Matveeva)

Show more

Monosaccharides, as well as the other carbohydrates, are used for the production of different chemicals including polyols which are widely used in food, medical, pharmaceutical industries. A large number of catalysts can be applied for these purposes but the main problem of numerous catalysts is instability leading to a high-speed deactivation, active phase leaching and support destruction. So the development of highly active, mechanically and chemically stable catalysts is one of the main tasks for the researcher...
