CATALYST SYSTEM FOR HETEROGENEOUS REACTIONS Russian patent published in 2017 - IPC B01J21/08 B01J35/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst system for heterogeneous reactions, which is a geometrically structured system including a microfibre of a high-silica support with diameter 5–20 mcm, which is characterised by presence in infrared spectrum of absorption bands of hydroxyl groups with wave number ν= 3,620–3,650 cm^-1 and half-width 65–75 cm^-1. Support has a jelly-like surface layer with thickness from 1 to 500 nm, which is characterised by viscosity of 3,000–30,000 cP and specific surface area, measured by BET thermal desorption of argon, S_Ar= 0.5–350 m²/g and, at least one active component.

EFFECT: technical result is high activity, selectivity and high resistance to deactivation in aggressive media.
