Ruthenium catalyst for ammonia synthesis deposited on carbon - Support obtained from synthetic resin

Carbon-based ruthenium catalysts were studied. The raw carbon material (CS) was obtained as a result of carbonization and activation of the resin - a derivative of styrene-divinylbenzene copolymer. After thermal treat ment of CS, activated carbon (C1900) was formed. Sorption and porosity measurement s of polymeric precursor and both carbon materials showed that distribution of mesopores in the activated carbon was determined by texture of the init ial polymer. Barium-promoted Ru/CS system had no catalytic activity in the reaction of ammonia synthesis, but the catalyst deposited on the thermally modified carbon (Ba-Ru/C-1900) was very active, much more than commercially applied fused iron catalyst.
