ABSTRACT

The reactivity toward O₂ of six petcokes with vanadium content between 0.05% and 0.26% has been assessed using both thermogravimetry (TG) and an entrained flow reactor (EFR). Very high reactivities were observed in TG experiments as compared with typical reactivities for carbon found in the literature. The reactivities are correlated with the vanadium content of the petcokes. This effect is less visible during combustion in the EFR.
The reactivities of the petcokes toward NO have been characterized through experiments in the EFR. These charcoals again exhibit very high reactivities. Vanadium again appears to have a catalytic effect on the reaction.
