    The paper describes a study on the formation of CuO/ZnO/Al2O3 at synthesis and calcination. The effect of crystallinity of copper and zinc oxides depending on the thermolysis temperature is shown. Data on activity and stability in the reactions of CO conversion and water-methanol fraction purification from of CH3OH are given. It is assumed that the precursor of the active state (in addition to the bulk phase fine CuO) is caused by the presence of isolated Cu2+ cations and clusters of copper (CuO)x in various oxide compounds. The obtained results are used in the development of catalysts for the purification of water-methanol mixture from CH3OH and steam conversion of CO.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ прСдставлСны Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ исслСдования ΠΎΠ±Ρ€Π°Π·Ρ†ΠΎΠ² с ΠΎΠΏΡ€Π΅Π΄Π΅Π»Π΅Π½Π½Ρ‹ΠΌ ΡΠΎΠΎΡ‚Π½ΠΎΡˆΠ΅Π½ΠΈΠ΅ΠΌ CuO/ZnO, ΠΏΠΎΠ»ΡƒΡ‡Π΅Π½Π½Ρ‹Ρ… Π°ΠΌΠΌΠΈΠ°Ρ‡Π½ΠΎ-ΠΊΠ°Ρ€Π±ΠΎΠ½Π°Ρ‚Π½Ρ‹ΠΌ способом ΠΈ мСханичСским смСшСниСм гидроксо-ΠΊΠ°Ρ€Π±ΠΎΠ½Π°Ρ‚ΠΎΠ² ΠΌΠ΅Π΄ΠΈ, Ρ†ΠΈΠ½ΠΊΠ° ΠΈ оксида алюминия.
