CATALYST FOR SELECTIVE HYDROGENATION OF PYRIDINE AND ITS DERIVATIVES AND THE PROCESS OF HYDROGENATION OF PYRIDINE AND ITS DERIVATIVES USING A CATALYST Russian patent published in 2022 - IPC C07C5/08 B01J21/04 B01J23/44 B01J23/50 B01J23/72 B82B1/00 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of catalytic technologies for processing raw materials containing nitrogenous heterocyclic compounds, and concerns, in particular, catalysts and a method for processing pyridine and its derivatives into valuable products: hydrogenated heterocyclic compounds. The claimed catalyst for hydrogenation of pyridine and its derivatives contains palladium and copper or silver nanoparticles with an average size of 2-3 nm on an aluminum oxide carrier.

EFFECT: claimed catalyst makes it possible to increase the selectivity of the process while maintaining a high conversion of the heterocyclic compound, as well as to increase the stability of the catalyst in successive hydrogenation cycles.
