Nickel-promoted mesoporous ZSM5 for carbon monoxide methanation

Synergistic effect of Ni and the mZSM5 support led to high methanation activity of Ni/mZSM5. Two possible reaction routes emerged: (1) adsorbed CO may be reacted with H 2 to form CH 4 and H 2 O; (2) adsorbed H may be reacted with CO to form CH 4 and CO 2 .
