Molybdenum Disulfide–Alumina/Nickel‐Foam Catalyst with Enhanced Heat Transfer for Syngas Sulfur‐Resistant Methanation

Abstract Sulfur‐resistant CO methanation by using MoS 2 ‐based catalysts possesses potential to produce synthetic natural gas from the direct use of un‐desulfurized syngas with a low H 2 /CO ratio in industry. However, hotspots raised in the high exothermic reaction lead to catalyst deactivation and an uncontrollable reactor temperature, both of which hinder industrial applications. A metal‐structured MoS 2 ‐Al 2 O 3 /Ni‐foam catalyst with stable MoS 2 active species and high heat‐transfer efficiency was synthesized to resist deactivation and to remove the heat of the reaction through a hydrothermal synthesis process. This catalyst exhibited superior activity and stability in the sulfur‐resistant methanation of syngas and has potential applications in highly exothermic and endothermic reactions.
