Fremgangsmåte ved fremstilling av ferrieritt |
摘要 |
Ferrierite is prepared by a method that provides extremely pure crystalline material. The method consists of preparing a mixture of silica, alumina, alkali metal and pyridine of a certain composition and heating said mixture to form the crystals. The SiO2/Al2O3 and OH<->/SiO2 are controlled to insure preparation of high SiO2/Al2O3 ratio, high surface area and high purity ferrierite. An olefin skeletal isomerization catalyst is prepared from a high silica to alumina ratio, high surface area and high purity ferrierite. |
