Cobalt catalyst supported on strontium carbonate (Co/SrCO_3) was successfully modified by Mg addition for high activity of dry reforming of methane at 0.5 MPa, 620℃, W/F=0.2 g・h/mol, feed composition=CH_4/CO_2/N_2=45/45/10. The cobalt catalysts were also modified by 9 additives (Na, Cs, Zn, W, Fe, Pr, Pd, Mg, Mn) which affected on both the activity and the characters of the catalyst. Physicochemical properties of these 9 elements were used for the regression models, which correlates the properties and the activity or the characters of cobalt catalyst. Then linear regression analysis performed to show the most influential character suggested that XRD peak intensity of (111) plane of strontium carbonate is important. Morphology and shape of the carbonate probably affects the catalytic activity.
