Impacts of vanadium and coke deposits on the CO2 gasification of nickel catalysts supported on activated carbon from petroleum coke

- V deposition significantly lowers initial gasification rate of Ni/AC catalyst.
- Coke deposition does not significantly influence rate of gasification.
- Adding V to Ni/AC catalysts significantly lowers coke deposition.
- V likely hinders Ni mobility during gasification leading to lower activity.
