Abstract

Abstract

Ni-CaO-ZrO₂ catalysts were prepared by co-precipitation under different conditions and used in the tri-reforming of methane; the influence of preparation conditions on methane conversion and catalytic stability was evaluated. The results indicated that the optimal parameters used to prepare Ni-CaO-ZrO₂ catalysts include a calcination temperature of 973 K, a pH value of 10~12 for co-precipitation, and a reflux duration of 24 h. The catalyst prepared under the optimal conditions has a proper surface area and Ni-ZrO₂ interaction; it exhibits promising catalytic activity and stability in methane tri-reforming, and the methane conversion exceeds 70% under a temperature of 973 K and atmospheric pressure.
