Abstract
The invention discloses a catalyst carrier material, a catalyst carrier and a preparation method thereof. The catalyst carrier material uses activated carbon as a core and alumina dried gum as a shell. The preparation method comprises the following steps: introducing activated carbon slurry into the process of gelling amorphous alumina; aging, molding, and drying to obtain the carrier material; molding or un-molding to prepare the carrier. According to the catalyst prepared from the catalyst carrier material or carrier, a reactant firstly contacts and reacts with the alumina serving as the shell layer, and is contacted with the activated carbon serving as the core layer to react, so that the advantages of alumina and activated carbon can be sufficiently utilized, the catalyst has relatively high reaction activity and using stability, and the service life of the catalyst can be prolonged.
