A detailed chemical kinetic modeling approach is used to examine the phenomenon of suppression of sooting in diesel engines by the addition of oxygenated hydrocarbon species to the fuel. This suppression, which has been observed experimentally for a few years, is explained kinetically as a reduction in concentrations of soot precursors present in the hot products of a fuel-rich diesel ignition ...

Methanol, formaldehyde, carbon monoxide, and propylene conversion were examined in a laboratory flow reactor over three base-metal containing alumina-supported palladium (Pd) catalysts in addition to Pd on y-alumina catalyst. The base metals were cerium, barium, and a combination of the two. Experiments were performed to determine the effect of air to fuel ratio on lightoff temperatures of vari...

Dual functions of BaCe0.8Y0.2O3−a ~BCY! as an electrolyte and as an anode were improved for solid oxide fuel cell ~SOFC! applications. A porous Ce-rich phase with fluorite structure was formed with a depth of ,10 mm from the BCY surface by vaporization of BaO from the BCY surface at 1700°C. The resulting BCY surface showed enough electronic conductivity to provide electrical collection and a hi...
