Hydrogenation catalyst and preparation method therefor and use thereof

Abstract

A dry gas hydrogenation catalyst and a preparation method therefor are provided. The dry gas hydrogenation catalyst have a carrier component containing aluminium oxide and an active hydrogenation component in the form of a sulfide on the catalyst. An average number of lamella layers of the sulfide is less than 1.5, and the proportion of a single layer is 65%-80%. The catalyst is prepared by (I) taking aluminum oxide powder A and roasting same at high temperature in an oxygen-containing atmosphere to obtain aluminum oxide dry gel powder B; II) impregnating the aluminum oxide dry gel powder B using the active hydrogenation component impregnating solution C, drying, roasting at high temperature in the oxygen-containing atmosphere, and sulfidizing same to obtain powder E; and III) molding, drying, and roasting the powder E prepared in step (II). The catalyst is effective in removing impurities such as oxygen, CO, and CO2.
