J. Sentek et al., Ruthenium catalyst for ammonia synthesis deposited on carbon - Support obtained from synthetic resin, PRZEMY CHEM, 78(10), 1999, pp. 363
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.
