Polymetallic Catalysts for the Process of Hydrogenation of Nitrocompounds

Abstract

Results of studies of humic substances in the quality of natural polymeric modifier for the coated palladium catalysts are presented in the paper, along with synthesis of new catalysts based on palladium – potassium humate, fixed on various inorganic carriers and their catalytic properties are studied. The catalysts may be placed in the following order according to activity: Pd-PHum/B-094 > Pd-PHum/Shungit (Sht), proc.1%КОН > Pd-PHum/Sht >> Pd-PHum/SiO2. More active and optimal are the catalysts of 0,8% Pd – Potassium’s Humat (1%)/B-94 and 0,8% Pd/Shungit 1% КОН.
