Kukhar Institute of Bioorganic Chemistry and Petrochemistry of the National Academy of Sciences of Ukraine popup.description1 Determination of the influence of changes in the structural and morphological characteristics of the domestic copper-zinc-aluminum oxide catalyst on its catalytic properties in the reaction of methanol production under the influence of vibration-acoustic oscillations. popup.description2 In accordance with the task of the second stage, a study was conducted of the course of the hydrogenation reaction of carbon oxides on the domestic industrial catalyst SNM-U under the influence of vibrational-acoustic oscillations. A complete comparative physico-chemical analysis of the industrial catalyst before and after the carbon oxide hydrogenation process was performed. During the research, it was established that the increase in the activity of the SNM-U catalyst is influenced by such structural and morphological characteristics as the average size of the copper crystallite, the morphology of the catalyst surface, its specific surface area, and thermogravimetric characteristics. A series of comparative studies of the catalytic characteristics of the industrial granular SNM-U catalyst was conducted using a working gas mixture (molar ratio CO:H2:CO2 = 1.0:2.92:0.24) of carbon oxides with/without the use of vibration-acoustic vibrations in situ. The results of the conducted studies show that the use of vibration-acoustic oscillations in situ with a frequency of 30 Hz and a meander signal shape in the process of hydrogenation of carbon oxides contributes to an increase in the productivity of the SNM-U catalyst for methanol by 2.6 times with an increase in selectivity by 16%. Carrying out the hydrogenation process under conditions of vibration-acoustic oscillations in situ showed that this is one of the promising factors influencing the increase or maintenance of the activity of already existing industrial catalysts during the process.
