NICKEL CATALYSTS PROMOTED BY FERROALOYS FOR BENZENE HYDRATION

Abstract

This paper presents the methodology and technology for modification of alloyed nickel catalysts for hydrogenation of benzene with ferroalloys. The effect of the nature of the catalyst metal, modifying additives, particle size, and technological parameters has been studied in detail. Reliable data were obtained on the phase, particle size and chemical compositions, porous structure, and sorption capacity for hydrogen, which explain the activity, selectivity and stability of the catalysts. The principles of scientific selection of optimal catalysts, modifying components for the selective hydrogenation of benzene are proposed. The synthesized nickel catalysts were tested in the process of hydrogenation of benzene to cyclohexane in the liquid phase.
