摘要：
The influence of contact between carbon black(CB), a model soot, and solid catalysts on the catalytic oxidation of CB was investigated under simulated gaseous conditions. Water condensation was found to have a big promotive effect on the carbon oxidation. The effect of reactant gas composition on the catalytic reaction was also studied for KVO3/SiC. The results showed that during the reaction process KVO3 partly changes into K2SO4 and V2O5 which are more stable and catalytically active under simulated gaseous conditions. Based on these results, a large number of single or mixed sulfates were screened. Most of them were found to be active for carbon oxidation. Among them, mixed sulfates containing vanadium were most active.
