Abstract
AbstractSulfur‐resistant CO methanation by using MoS2‐based catalysts possesses potential to produce synthetic natural gas from the direct use of un‐desulfurized syngas with a low H2/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 MoS2‐Al2O3/Ni‐foam catalyst with stable MoS2 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.
