The Reaction Scheme of Partial Oxidation of Methane to Synthesis Gas over Metallic Ni Catalyst

A metallic Ni catalyst was prepared with nickel sponge, followed by acid treatment. The reaction scheme of partial oxidation of methane to synthesis gas over the metallic Ni catalyst had been suggested and researched. For defining the logical kinetic regime, the effects of operational variables on mass and heat transport resistances were investigated. In the absence of significant mass and heat transfer resistances, high selectivities to syngas were obtained on the metallic Ni catalyst even in the low methane conversion range. With the increase of CH4/O2 ratios, the selectivities to H2 and CO on the metallic Ni catalyst also increased.
