Obtainment of Sorbitol on Ferroalloy Promoted Nickel Catalysts

Abstract

The systematic study of the activity of the catalyst suspended with ferroalloys additives in catalytic hydrogenation of glucose over a wide variation of process parameters is given in this article. Since nickel catalysts were studied sufficiently, we limited to the data of the phase composition and structure; specific surface of alloys and catalysts based on aluminum-nickel alloys, modified ferroalloys. Results of the study of phase, chemical, particle size distribution and structure of nickel alloys and catalysts have shown that modifying metals affect to the ratio of NiAl 3 /Ni 2 Al 3 in the alloys, crush crystals, increase catalyst particle size, surface area and large size pore volume and simultaneously increase the micro-and supermicro pore ratio. Highly active, stable and selective catalysts based on nickel for the sorbitol synthesis process was developed.
