Zeolite β was aluminated with aqueous solution of NaAlO2. The product was characterized by means of XRD, FTIR techniques. After alumination, the Si/Al ratio of zeolite β is greatly decreased (from 15.2 to 3-4), and the crystallinity is retained mostly. Alumination is favoured by increasing the amount of added NaAlO2 and temperature, a proper high pH condition is also favourable. However, too high alkalinity leads to the destruction of the framework.
