The possibility of introducing nitrogen into the structure of the carbon material Sibunit by its hightemperature treatment in a flow of ammonia at 800–1000°C was studied. It was shown that preliminary oxidation of the Sibunit surface with a 5% nitric acid solution promotes more efficient nitrogen binding, which may be due to oxygen-containing groups and/or greater defectness on the surface of the oxidized carbon material. Palladium on Sibunit preoxidized and treated in NH3 at 1000°C leads to an increase in the activity and selectivity of the Pd/Sibunit catalyst in the reaction of hydrogenation of acetylene to ethylene. It was established that the improvement of catalytic characteristics is associated with the increased availability of supported palladium due to its localization in larger pores of the N-modified support.
