Abstract: The acidic properties of SAPO-11 molecular sieve were studied by IRand TPD methods. The catalytic properties of n-heptane cracking and ethanol dehydration on SAPO-11, HZSM-5 and SAPO-5 were performed. The results indicated that both Bronsted and Lewis acid sites are present in the sample of SAPO-11. From the spectra of NH3-TPD on SAPO-11 the amount and strength of acid sites were measured and NH3 desorption activation energy was calculated, showing that it has medium acidic strength.
Key words: Molecular sieve SAPO-11, Acidic properties, Catalysis of heptane cracking and ethanol dehydration
