A study was conducted on the effect of key reaction parameters such as catalyst bed temperature, gas space velocity, plasma supply voltage, CH4/CO2 conversion, and selectivity of H2 and CO. Each experiment was carried out in two distinct regimes using the same charge of the catalyst with and without the presence of plasma to determine the degree of catalyst deactivation from run to run, ending with a near-complete deactivation of the catalyst eventually recorded for the first stage and rapid recovery in the plasma stage.
While there are several possible explanations for the unexpected in-situ reactivation of the catalyst, the finding justifies further studies using already deactivated Ni/Al2O3 catalyst to determine the most efficient plasma-assisted reactivation protocol.
