Microporous ceramic catalyst carrier and preparation method thereof
The invention discloses a microporous ceramic catalyst carrier and a preparation method thereof, and relates to the technical field. The base material is prepared from the following components in parts by weight: 30 to 50 parts of bauxite, 47 to 60 parts of fused quartz and 10 to 36 parts of porcelain clay; the adhesive is prepared from the following components in parts by weight: 10 to 14 parts of heat-resistant phenolic resin, 23 to 26 parts of fumed silica and 10 to 16 parts of mica powder. According to the microporous ceramic catalyst carrier, the bauxite is used as a main base material to replace aluminum oxide, and the bauxite internally contains silicon oxide with low content, so that the bauxite can be better fused with fused quartz during sintering to reduce the sintering temperature, improve the molding rate and enhance the wear resistance, and after the microporous ceramic catalyst carrier is molded, the service life of the microporous ceramic catalyst carrier is prolonged. The composite material has the advantages of low density, high strength, compression resistance, stable chemical property, high universality, no pollution, capability of being assembled in various shapes and adaptability to complex reaction design.
本申请公开了一种微孔陶瓷催化剂载体及其制备方法，涉及技术领域。本申请包括以下的原料：基料，所述基料包括以下重量份的组分：铝矾土30—50份、熔融石英47—60份、瓷土10—36份；粘合剂，所述粘合剂包括以下重量份的组分：耐热酚醛树脂10—14份、气相二氧化硅23—26份、云母粉10—16份。本申请通过铝矾土为主要的基料，用其代替氧化铝，由于其内部的还含有氧化硅且含量不高，在进行烧结时，能够更好地与熔融石英进行融合，用于降低烧结温度、提高成型率和增强抗磨性，进而使得当该微孔陶瓷催化剂载体成型后，具有密度小，强度大，抗压，化学性质稳定，普适性强，无污染，可多种形状组装，适应复杂的反应设计的优点。
