| Abstract: | AlPO 4 5,SAPO 5 and TAPO 5 molecular sieves which were synthesized by hydrothermal method were used as the catalysts of isomerization of m xylene.The property of isomerization is evaluated and the structure and acidity of the three catalysts are characterized.It was indicated by correlating the acidity and the property of isomerization that the Bronsted acid is the active center of m xylene isomerization,TAPO 5 has the highest isomerization activity(54.93%) and selectivity(93.41%) because of their highest Bronsted acid center.The isomerization selectivity of xylene over TAPO 5 is related to the intensity of Bronsted acid center. |
