Partial oxidation of butane to syngas over nickel supported catalysts modified by alkali metal oxide and rare-earth metal oxide

The partial oxidation of butane (POB) to syngas over nickel supported catalysts was first investigated with a flow-reactor, TG and UVRRS. The NiO/gamma -Al2O3 is the most suitable for the POB among NiO/gamma -Al2O3, NiO/MgO and NiO/SiO2. And the reaction performance of the NiO/gamma -Al2O3 shows little difference from those of the nickel supported catalysts modified by alkali metal oxide and rare-earth metal oxide. However, modification with Li2O and La2O3 can suppress carbon-deposition of the NiO/gamma -Al2O3, which contains graphite-like species during the POB reaction
