INFLUENCE OF THE NATURE OF THE CARRIER ON THE AlO BASE ON THE PROPERTIES OF THE CATALYST FOR LIQUID-PHASE HYDROGENATION

The influence of crystalline modification of aluminum oxide-based substrates for nickel catalysts on the activity in the reaction of liquid-phase hydrogenation of multiple carbon bonds in molecules of various classes of organic compounds is considered. The basic physicochemical and textural properties of the applied nickel catalysts obtained by the impregnation method are presented. The influence of textural properties of the carrier on the main kinetic regularities of the hydrogenation reaction is shown. The presence of individual forms of adsorbed hydrogen on the studied catalyst samples has been established, and the possibility of using the IR spectrometry method to solve this problem has been shown.
