Catalytic activity of Ni-intercalated montmorillonite clay and some other Ni loaded oxides were studied for methanation of low-temperature volatile matter of the Shinyubari coal. Among these catalysts, Ni-montmorillonite exhibited the highest activity in methanation of the low temperature volatile matter below 600 t with a conversion of 95% on the carbon basis.<BR>It was found that the catalytic activity of Ni metal changed by using different support materials. The order of the methanation activity was determined as: montmorillonite>zeolite (MS-5A) <TiO<SUB>2</SUB><α-Al<SUB>2</SUB>O<SUB>3</SUB><MgO>SiO<SUB>2</SUB>≅γ-Al<SUB>2</SUB>O<SUB>3</SUB>.<BR>The structure of Ni-montmorillonite catalyst was investigated by the TG, XRD and FT/IR methods, which revealed that the metallic Ni was highly dispersed on the surface and the interlamellar surface of montmorillonite.
