Investigation on the Effect of Surfactant on the Structural and Activity of Nickel Catalyst Supported on Magnesium Oxide in Dry Reforming of Methane

In this paper, three polymeric surfactants (PVA¡ P123 and PEG) were used for preparation of magnesium oxide with precipitation method. The prepared samples were evaluated by XRD¡ BET and SEM techniques. The results showed that the surfactant has a positive effect on the surface area and pore size of magnesium oxide. The magnesium oxide prepared by PVA has the highest surface area among the prepared samples. The catalytic results of 10%Ni catalysts supported on MgO prepared by different surfactants in dry reforming of methane revealed that all catalysts have a high catalytic activity and stability and the nickel catalyst supported onmagnesium oxide prepared with P123 has the highest activity in dry reforming of methane.
