Effects of support on the kinetics of carbon hydrogenation on nickel

摘要: Abstract The kinetics of carbon hydrogenation on 3% Ni/Al 2 O 3 , Ni/SiO and Ni/TiO were determined gravimetrically under conditions representative CO i.e., 423–503 K, 1 atm total pressure, P H = 5–10 kPa, coverages 0.1–0.3. activation energy for nickel is independent support. However, specific rates these catalysts vary by as much a factor 10 decrease in the order ; moreover, reaction with respect to hydrogen significantly higher relative . Thus, differences those are even greater at high also dissociates more rapidly Accordingly, activity explained its activities both dissociation hydrogenation.
