The preparation was studied of supported catalysts with different contents of platinum (0.21 to 9.25%) on activated carbon, suitable for liquid phase hydrogenations in mild conditions. The catalyst activity was tested in hydrogenations of nitrobenzene and 1-octene in ethanolic solutions at 25 °C and atmospheric pressure of hydrogen. The highest specific activity was achieved by applying the following conditions: content of the active metal 0.5% Pt/C, calcination temperature 200 °C, and temperature of the subsequent reduction with hydrogen 100 °C.
