Increased Catalytic Activity Caused by Local Destruction of Linear Zeolite Channels: Effect of Reduction Temperature on Heptane Conversion over Platinum Supported in H-Mordenite

Kinetics of Hydro-isomerization ofn-Hexane over Platinum Containing Zeolites

“…The dashed line shows a different trend because the 3 wt% sample showed a strong increase in hydro-isomerization activity. We attribute this to local destruction of the mordenite framework caused by growth of large platinum particles (26,27). The presence of large metal particles was confirmed by a relatively low H/Pt and a low qTOF Pt in the liquid phase hydrogenation (Table 4).…”

Factors affecting isomer yield for n-heptane hydroisomerization over as-synthesized and dealuminated zeolite catalysts loaded with platinum

“…WHSV = 7 h −1 , H 2 /n-C 7 (molar) = 16, total pressure = 100 psig, and 0.5 wt% Pt loading (using H 2 PtCl 6 ) on all catalysts. a region close to the pore mouth, resulting in a lower activity [2,9,20]. Differences in activities of the various zeolite catalysts could also be attributed to intrinsic differences in zeolite acidity.…”

Fabrication and Testing of Copper/Gadolinium‐Doped Ceria‐Based Solid Oxide Fuel Cells Operating at Intermediate Temperature

“…One strategy can be the addition of Co into the anodic cermet, CuO/CeO 2 /Co cermet having been demonstrated to be stable even in the presence of H 2 S up to 450 ppm . Alternatively, Cu/CeO 2 /YSZ composite anode could be used and the overall performances of the cells proposed in the present work could be obviously improved in biogas if low percentages of metals such as Ni, Ru or Rh are included in the anodic composition …”
