The kinetics of reactions of liquid-phase hydrogenation of sodium acrylate on catalysts has been studied. Ni/SiO2 with different amounts of deposited nickel were used as a catalyst, as well as samples with controlled partial deactivation of the surface by sulfide ion. Approaches to determining the amount of reduced metal on the catalyst surface and the amount of catalytic poison required to deactivate active centers are shown. Hydrogenation reaction rates and activity were measured. Kinetics were modeled, and rate constants of hydrogenation, adsorption, and desorption of hydrogen were obtained. The number of active centers and their ratio to metal atoms located on the catalyst surface were estimated.
