Two commercial methanation catalysts Ni/Al_2O_3 were taken as example for examination. Both crushed and pelleted catalyst were used. Their catalytic activities were evaluated under different reduction conditions. It was found that the reduction process is of vital importance in developing the activity. Each catalyst has its own appropriate condition to display its intrinsic property. So it is really unreasonable to compare the activity of different catalysts under same testing condition. In this paper we present a procedure for exploring the optimum activity of the two catalysts with their corresponding data, which are quite different from each other and from the previous ones.
