LSX型体分子筛焙烧与二次晶化试验研究
LSX Type Molecular Sieve Body Roasting and Secondary Crystallization Research
摘要
Abstract
Based on the low-silica X (LSX) powder, kaolin and LSX type molecular sieve as the research object , the crystalline phases and thermal stability were characterized by means of XRD and TG-DTA, and the effects of different crystallization conditions of static water adsorption ca-pacity were investigated on LSX type molecular sieve .The studies in this paper showed that with the increase of roasting temperature , the crystallinity of LSX powder was destroyed , and kaolin was gradually transformed into metakaolin .The optimal roasting temperature of LSX type molecular sieve body was 600 ℃.When the secondary crystallization temperature was 95 ℃with 5 h crystal-lizing in 2 mol/L sodium hydroxide solution , the best static water adsorption capacity of LSX type molecular sieve reached 33 .5%.关键词
