STUDY OF CATALYTIC PROPERTIES OF p-EGM/AC-Ni0-Co0, p-PGM/AC-Ni0-Co0 METAL-POLYMER COMPLEXES

Abstract

Catalytic hydrogenation is one of the most important processes used in chemical industry. Metal-polymeric complexes demonstrate the high level of catalytic activity, stability and selectiveness of effect. Reducing of catalyst particles up to nanometric dimensions lets us to broaden polymer surface contacting with reaction medium and to increase effectiveness of catalysis in several times, and gel matrix preserve particles against of coagulation and oxidation. So, at the present day the search of new catalytic systems, particularly nanocatalysts characterized with high degree of activity and selectivity is the relevant task. The aim of theis work is the investigated the catalytic properties of metal-polymer complexes of p-EGM/AK-Ni0-Co0, p-PGM/AK- Ni0-Co0. In our investigation a hydrogenation reaction of pyridine was chosen as a model reaction. Hydrogenation of pyridine was carried out without a catalyst, with a skeleton catalyst and on a metal-polymer complex at current strengths of 0.5; 1; 1.5; 2А at temperatures of 298К, 303К, 308К and 313К. Based on the results was established the dependence of the rate of hydrogenation of pyridine in the presence of bimetallic polymer complexes on the strength of current.
