The results of this study demonstrate that the Ir-promoted Ni/Al/sub 2/O/sub 3/ catalyst possesses several valuable and superior characteristics when used for catalytic methanation under typical industrial conditions. These properties include: higher activity by a factor of > 2 than that of the unpromoted Ni/Al/sub 2/O/sub 3/ catalyst; enhanced resistance to deactivation by hydrogen sulfide during exposure to contaminated feedstock, as manifested by the prolonged high methanation activity and extended service lifetime; and high resistance to carbon fouling.
