Initiation of Oxidative Reforming of Butane over Praseodymium Oxide Supported Ni Catalysts at Ambient Temperature

Abstract

The catalytic characteristics of various rare-earth oxide supports for Ni catalysts were investigated for the initiation of the oxidative reforming (OR) of C₄H₁₀ at ambient temperature. Ni/PrO_1.83, reduced at 873 K, successfully initiated the OR of C₄H₁₀ as previously reported for Ni/CeO₂. PrO_1.83 undergoes reduction by H₂ at 873 K and subsequent oxidation at ambient temperature, so the catalyst is heated to initiate the auto-ignition temperature (633 K) of C₄H₁₀ OR over the catalyst.
