COPPER-CHROMIUM-ZINC CATALYST FOR HETEROGENEOUS REACTIONS Russian patent published in 2015 - IPC B01J23/86 B01J23/80 B01J21/12 C01B3/16 C07C209/36 C07C211/46 C07C211/48 

FIELD: chemistry.

SUBSTANCE: a copper-chromium-zinc catalyst for heterogeneous reactions, which includes copper, chromium, zinc and aluminium oxides and an additional component is disclosed. The catalyst contains, as the additional component, 0.5-5 wt % of a silicon compound with respect to the oxide and the catalyst is formed via heat treatment of aluminium hydroxide together with compounds of said components, and has a porous structure with total specific pore volume of not less than 0.25 cm³/g and content of mesopores with a diameter of 10-40 nm higher than 60%, and the catalyst has the following composition, with respect to oxides, wt %: CuO 50.0-57.0; Cr₂O₃ 11.0-16.0; ZnO 9.5-13.0; SiO₂ 0.5-5.0; aluminium oxide - the balance.

EFFECT: forming a copper-chromium-zinc catalyst having high strength, thermal stability and which can be used in different chemical processes.
