The invention relates to a catalyst carrier used for generating gas pulse in a reactor. The outer shape of the catalyst carrier is in a circular cake shape (flying saucer shape). The catalyst carrier is composed of a plurality of unit holes. The structure of each unit hole is that two ends of unit hole are prismoids and the middle portion of the unit hole is a hollow neck (weir groove), wherein the prismoids are preferably triple prismoids, quadruple prismoids or pentagonal prismoids, hexagonal prismoids, regular circular truncated cones, etc. The catalyst carrier is made of chemical ceramic materials. The chemical ceramic materials comprise the following raw materials of, by weight, gibbsite, 25-35 parts of kaolin, 10-20 parts of Guizhou soil, 5-10 parts of talcum, 8-12 parts of feldspar and 8-12 parts of alkali metal oxide. The catalyst carrier is suitable for being used as a carrier for the catalyst of the field of petroleum chemistry or as filling materials in the reactor. The carrier with the structure enhances a mass transfer effect and a heat transfer effect between gas and liquid, and further increases catalytic effect of the catalyst and reaction rate. The catalyst carrier has high hardness, high strength, large specific surface area, good high temperature resistance and good acid and alkali resistance.
