Abstract
The invention relates to a CO methanation catalyst and a preparation method and application thereof in the field of catalysts. The catalyst comprises an active component, an auxiliary agent and a macroporous alumina microsphere carrier. The active component is selected from at least one of Ni, Fe and Co, the auxiliary agent is selected from at least one of alkaline earth metal, transition metal or rare earth metal, the alumina microspheres are alumina of theta and / or delta phase, the aperture is greater than 15nm, the water absorption rate is higher than 150%, and the sulfur content is 0.01-0.2 wt%. The CO methanation catalyst is prepared by the following steps: impregnating the components including the active component and the auxiliary agent on the carrier by adopting an impregnation method, and then drying and roasting. According to the catalyst, under the action of the carrier, the dispersity of the active components is higher, the water absorption rate is higher, and the catalyst has good activity and can be used for CO methanation reaction.
