Skeletal isomerizations of n-pentane and n-butane have been studied at 11 bar in a microflow reactor over platinum containing sulfated zirconia (PtSZ) catalysts. The isomerization rate of n-pentane is about seven times higher than that of n-butane; s

When small molecules inside one-dimensional micropores of zeolites are unable to pass along each other, transport is limited by single file diffusion . Product molecules generated inside such micropores are unable to escape to the gas phase if the po

The dependence of the deactivation rate of Cu/ZSM-5 lean NOxreduction catalysts on the composition of the feed was studied. No catalyst deactivation was observed in the absence of H2O at 400°C after 160 h. Catalyst deactivation was much faster if th

The conversion of methylcyclopentane (MCP) has been studied overzeolite Y supported rhodium catalysts with a variety of protonconcentrations. Ring opening (RO) of MCP to hexane isomers iscatalyzed by metal sites, but ring enlargement (RE) of MCP tocy

Isomerization of small alkanes is compared over two bifunctional catalysts with similar concentrations of metal and acid sites and similar strenths of Bronsted acid sites. The catalytic performance and the kinetic parameters are significantly differe

The nature of adsorbed nitrogen oxide complexes (NO y ) has been identified by FTIR spectroscopy. Nitrito groups are most prominent on Co/ZSM-5. These complexes are stable at 150°C in He but are reduced upon exposure to either C 3 H 8 or CH 4 leadin

Exchange of [Rh(NH3)5(H2O)]3+ ions from aqueous solution into NaY starts at the surface of the zeolite grains; ion penetration into subsurface cavities is slow. A marked rhodium concentration profile from the surface to the interior of the granuli va

Mossbauer spectroscopy, temperature programmed reduction (TPR), and FTIR of adsorbed CO show that ion exchange of [Rh(NH3)4Cl]Cl2 and FeSO4 into NaY, followed by calcination and reduction in H2 up to 500°C, leads to Fe2+ ions and bimetallic RhFe clu
