NANOSTRUCTURED CATALYST FOR SELECTIVE HYDRATION OF ACETYLENE Russian patent published in 2021 - IPC B01J23/44 B82B3/00 B82Y40/00 B01J21/04 B01J23/72 B01J23/52 B01J23/50 

FIELD: nanotechnology.

SUBSTANCE: invention relates to a nanostructured catalyst for the selective hydrogenation of acetylene, consisting of a nanostructured carrier containing, wt.%: aluminosilicate nanotubes 40-80, aluminum oxide 20-60, palladium in an amount of 0.01-2.0% of mass of the carrier and a metal of group I-b Periodic table of chemical elements in the amount of 0.01-8.0% of the mass of the carrier, deposited on the surface of the carrier and intercalated into the inner cavity of aluminosilicate nanotubes.

EFFECT: invention increases the selectivity of the catalyst due to the intercalation of nanoparticles of palladium and a metal of group I-b of the Periodic Table of Chemical Elements into the inner cavity of aluminosilicate nanotubes and the formation of a highly dispersed active phase, which provides an increase in the contact area of hydrocarbon feed molecules with catalytic centers.
