摘要: Abstract This work was undertaken to investigate the behavior of ethane hydrogenolysis reaction over well-characterized, chlorine-free, silica-supported ruthenium-copper catalysts. The total dispersion all catalysts about 29%. studies were carried out in a laboratory-scale reactor, and catalyst activity correlated with ruthenium surface composition, as measured previously by using nuclear magnetic resonance spectroscopy chemisorbed hydrogen. Monte Carlo simulations used assist interpretation results. indicate that Cu: Ru atom ratio greater than 1:9 have constant specific (rate per atom), analogous single crystal surfaces. Below this ratio, drops rapidly copper is added system at lower temperatures studied. At modeling suggests edge corner sites crystallite are occupied copper. We conclude sensitive structure but no geometric effects observed.
