[Enlargement test of synthesis of MCM-22 zeolite by means of XRD].
On the basis of MCM-22 zeolite synthesis at the static condition in 100 mL lined PTFE autoclave, 250 and 1000 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 resultsshow 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.
