“…For the oxidation of a mixture ane, 2,3-dimethylbutane, cyclohexane), Stein et al published a ranking list of catalytic activity shown below [30]: the inactive oxides are not correlated with A~G . Those rate constants also are gathered on a straight line, but this line runs parallel to the axis of ARC.…”

Several kinds of diesel soot filters and filter materials of high melting points with eleven different catalytic coatings were prepared. They were calcined at a maximum temperature of 1000°C. The reaction rate and the kinetic parameters of the combustion of diesel soot were determined in a closed loop laboratory reactor. A packed bed of alumina particulates was the most active filter in soot combustion. Catalytic coatings with oxides of vanadium, copper or cerium accelerated the reaction. In each case the effect of the coating was dependent on specific interactions between the catalyst and the filter material. The manner of filtration and the nature of the soot filter are found to be more important for the overall result than the nature of the catalytic coating.

“…The convenience and rapidity of the microreactor make it especially attractive for comparing different catalysts for the same reaction {53, 72, 75, 110). Various catalysts were investigated for efficacy in the oxidation of automobile exhaust {1, 22,43,96,97); catalysis by semiconductors {28-31) was investigated by similar procedure. Silica-alumina catalysts were tested for cracking isobutane and cumene {70), for the depolymerization of ethylene {71), for the isomerization of cyclopropane {60), isobutane (77), and isopentane {64), and for the conversion of acetaldehyde {44).…”

Methanol conversion was carried out on a mesoporous material-chromia/ montmorillonite K10 (MK10)-in a pulse microcatalytic system. Methanol was converted to formaldehyde and ethylene by two different mechanisms. Methanol dehydrogenation increases by increasing reaction temperature (300-400 • C) and as chromia loading decrease. On the other hand, the dehydration of methanol occurs at a higher temperature (400-500 • C) and as chromia loading increase, 3-18% Cr. Redox and exposed nonredox Cr 3+ are responsible for formaldehyde formation. There is a relationship between increased C 2 H 4 production and the increase of Cr 6+ phase according to the acidity of chromia catalysts 34 and 76 µL tert-Butylamine/g catalyst for 3% Cr and 18% Cr, respectively. Formaldehyde formation is diffusionally controlled at high temperatures (400-500 • C) and kinetically controlled at a lower reaction temperature (300-400 • C), while methanol dehydration to ethylene is surface reaction controlled at 400-500 • C.
