Kiss, Goran C. Bošković, Matilda M. Lazić, Gizela A. Lomić, Radmila P Marinkvić-Nedučin] Summary: The activity of co-precipitated NiO-Al2O3 catalyst for partial oxidation of methane in a steel flow reactor was investigated. The catalyst samples loaded with 5, 10 and 20 wt.% nickel before use were thermally treated at 400, 700 and 1100oC. The feed gas for catalytic oxidation was prepared by dilution of natural gas with air, and had approximately the following volume composition: CH4: O2: N2 = 5: 2: 8. The reaction was carried out over 100 mg unreduced NiO-Al2O3 catalyst at gas flow rate of 50 cm3/min at 650oC and atmospheric pressure. The catalyst activity with 5 and 10 wt.% of nickel was very similar, decreasing with enhance of previous heat treatment. Further nickel loading did not increase significantly the catalyst activity compared to low level nickel samples. However, high nickel content has a levelling effect on catalyst activity, suppressing the undesired effect of previous heat treatment at high temperature Springer-Verlag/Akadémiai Kiadó, 2006 methane nationallicence partial oxidation nationallicence catalyst nationallicence nickel loading nationallicence NiO-Al2O3 nationallicence Kiss Ernő E.
