Abstract
Several molecular sieves with typical structures have been successfully synthesized.The pore structure and acidity of these molecular sieves were characterized by BET and NH3-TPD.Furthermore,the catalytic perfor-mance of these molecular sieves was investigated in C8 aromatic isomerization.The results indicated that the pore structure and acidity of catalysts are the key factors for C8 aromatic isomerization,the former was responsible the reaction type,while the latter was closely related to the reaction activity and selectivity.The C8 aromatic isomerization catalyst with high performance should have appropriate pore structure and acidity.
