Investigation of the phase composition and structure of stationary catalysts to increase safety of agrarian-and-food production

The phase composition and structure of stationary nickel-aluminum promoted catalysts have been studied. It is shown that the consists intermetallic compounds NiAl, NiAl3, Ni2Al3. Changes in microscopic alloys are determined. Modern methods for evaluating hydrogenation catalysts, as well analyzing raw materials products catalytic hydrogenation, established. highest performance characteristic whose consist Ni2Al3×4NiAl3 compounds. New modifications alloyed nickel-copper-aluminum with addition vanadium (0.5-2.5 %), rhodium (0.5 %) palladium (0.05 process pre- contact cottonseed oil studied developed. has lowest content transisomerized acids tallow achieved at a 1.5 % catalyst. ratio fatty-acid triglycerides target dietary fats was determined, ensuring their increase nutritional value safety. conditions under which results were obtained presented.
