The hydrothermal conversion of FAU type zeolite with various structure-directing agents was investigated.The highly crystalline and pure RUT and MTN type zeolites were obtained in the presence of tetramethylammonium hydroxide and benzyl-trimethylammonium hydroxide,respectively.As compared to amorphous silica/gamma-Al2O3 source,the crystallization rate for the formation of RUT type zeolite was clearly faster when FAU type zeolite was employed as Si and Al sources.hydrothermal conversion,FAU,RUT,MTN.
