Catalyst carrier, and preparation method and application thereof

Abstract

本发明涉及一种用于反应器中产生气体脉冲的催化剂载体,外形为圆饼形(飞蝶形),由多个单元孔组成,所述单元孔的结构是:两端为多棱台结构,中间为连续的中空缩颈(即堰槽),其中多棱台优选正三棱台、正四棱台或正五棱台、正六棱台、正圆棱台等。本发明催化剂载体由化工陶瓷材料制成,所述化工及陶瓷材料含有下列重量份的原料,三水铝石25-35份,高岭土25-35份,贵州土10-20份,滑石5-10份,长石8-12份和碱金属氧化物8-12份。适用于石油化工领域催化剂的载体或反应器中的填料,该结构的载体使得气液之间的传质和传热效果大大增强,进而提高催化剂的催化效果,提高反应速率,本发明催化剂载体不但具有高的硬度、强度比表面积大还具有很好的耐高温、耐酸碱性。
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.
