Partial Oxidation of Gasoline over Ni/al2o3 Catalysts Using Nickel Aluminate as Precursor

Gasoline, which currently presents a well-developed distribution network, represents an ideal fuel source for H2 production onboard or in stationary facilities. In this work, a novel alumina supported Ni (NiAl2O4/Al2O3) catalyst derived from the reduction of nickel aluminate at high temperature was investigated for the partial oxidation of isooctane, which was selected as a gasoline surrogate. While being relatively active in the process due to its small crystallite size, the catalyst did not show a stable behavior with time on stream since a considerably coke formation was noticed. Interestingly a better performance in terms of conversion, yield of hydrogen and stability was observed when water was added to the feedstream.
