The catalytic properties of Pd and Pt supported on woven glass fabrics were explored for liq.-phase hydrogenation of benzaldehyde as a model for three-phase catalytic reaction. The catalysts demonstrated high activity and are suitable materials to be used ...
Fiber catalysts are easy to handle and free of mass-transfer resistance. This report is the first application of cloth catalysts to water denitrification. In this work, cloths woven from glass fibers (GF) of 7–10 mm in diameter, impregnated with Pd, were t ...
The principal objective of this thesis is the development of a palladium catalyst supported on woven fabrics of activated carbon fibers (ACF) for the reactions of hydrogenations in liquid phase and the design of multiphase reactors using the characteristic ...
Pd nanoparticles (2 nm) stabilized in the micelle core of poly(ethylene oxide)-block-poly(2-vinylpyridine) were studied in partial hydrogenation of 2-butyne-1,4-diol. Both unsupported micelles (0.6 kg Pd/m3) and supported ones on g-Al2O3 (0.042% Pd) showed ...
The catalytic properties of Pd and Pt supported on woven glass fibers (GF) were investigated in the three-phase hydrogenation of nitrobenzene (NB). Over all catalysts, a 100% yield of aniline was attained. The catalytic activity for the best catalysts was ...
The electrochem. promotion of RuO2 catalysts interfaced with yttria stabilized zirconia was studied for the combustion of ethylene. The complete oxidn. of ethylene can be described by an Eley-Rideal type mechanism. In situ work function measurements were u ...
Microchannel reactors promise to display unusually fast response behavior to sharp changes of feed compn. in heterogeneous catalytic systems. In an attempt to use this feature for the elucidation of the transient kinetics and possibly for performance enhan ...
Reaction kinetics and catalyst deactivation during the redn. of NO with CO on a 0.5%Pt-3.4%MoO3/a-Al2O3 catalyst were investigated. The reaction shows an ignition/quenching behavior. After ignition, the reaction kinetics (formation of N2 and N2O) obey the ...

The oxidn. of CO on silica-supported hematite (Fe2O3) was studied by the step-response method in a tubular fixed-bed reactor at temps. 270-350 Deg. The oxidn. process appeared to proceed in two stages. First, oxygen atoms adsorbed on the surface of hematit ...
