The invention discloses a bird-nest catalyst carrier, which comprises a body (1). The body is cylindrical or cuboid; and honeycomb holes (2) which are uniformly distributed, and parallel or staggered vertically and staggered or parallel horizontally are formed in an inner cavity of the body. One or a mixture of more of activated aluminium oxide, zirconium oxide, magnesium oxide, silicon carbide, titanium dioxide and natural clay is taken as a main raw material, is added with an adhesive, a fusing agent and a proper amount of water, and is subjected to ball milling, kneading, ageing, mixing, molding, drying, shaping, cutting and low-temperature sintering to form the bird-nest catalyst carrier. Due to large specific surface area and void ratio, large internal through pore diameter and large pore volume, the bird-nest catalyst carrier can improve the total effective contact quantity to the greatest extent and shorten the flowing path of raw oil in the catalyst, so that the catalyst in the carrier can fully achieve the effect, and the raw oil flowing through the catalyst is fully separated, adsorbed, purified and filtered.
