Abstract

The hydrodechlorination reactions of chlorobenzene and 1,2‐dichlorobenzene on a NiMo/γAl~2~O~3~ catalyst were examined in a differential microflow reactor. The NiMo catalyst had high activity and selectivity for dechlorination; no hydrogenation of the aromatic ring was detected. The dechlorination reactions were examined at temperatures ranging from 275 to 375°C. In this temperature range the rates of adsorption and surface reaction are comparable and neither controls the overall reaction rate. A kinetic model, incorporating adsorption, desorption and surface reaction rates, has been used to model the data.

Catalytic supercritical water oxidation occurs through a combination of reaction pathways, consisting of heterogeneous oxidation on the surface of the catalyst and homogeneous oxidation in the solvent. The overall reaction rate should be a combination of the rates of the individual pathways and thus

Double-charge-transfer spectrometry was used to measure double-ionization energies to ground and electronically excited states of various chlorobenzenes. Since OH+ was the projectile ion used in these experiments, it is probable that triplet states of the dications were populated because of spin con
