摘要
在100,250和1000mL高压釜静态成功合成MCM-22分子筛的基础上,在2,5和200L高压釜中进行了MCM-22分子筛的动态合成试验,对合成的样品用XRD等技术进行了表征。结果表明,在静态和动态条件下合成的样品,全部为纯相MCM-22分子筛,且结晶度较高,从100mL到200L的放大试验是成功的。
On the basis of MCM-22 zeolite synthesis at the static condition in 100 mL lined PTFE autoclave, 250 and 1 000 mL stainless steel autoclave respectively, the synthesis of MCM-22 zeolite was studied at the rotating condition in 2, 5 and 200 L autoclave respectively. The samples as-synthesized and calcined were characterized by means of XRD and so on. The results show that all the synthesized samples are the pure MCM-22 zeolites, and their crystallinities were high, and MCM-22 zeolite can be synthesized successfully at the rotating condition in 200 L stainless steel autoclave.
