Abstract

The influence of crystalline modification of aluminum oxide-based substrates for nickel catalysts on the activity in the liquid-phase hydrogenation reaction of multiple carbon bonds in molecules of various classes of organic compounds is considered. The main physical, chemical and textural properties of deposited nickel catalysts obtained by impregnation are presented. The influence of the 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 was established, and the possibility of using the IR spectrometry method to solve this problem was demonstrated.
