摘要

Mesoporous aluminosilicates were synthesised with and without lanthanum. Their acidic properties were characterised by TPD of ammonia and by the isomerisation of m-xylenc and the results compared with those obtained for a microporous ZSM-5 zeolite. It was found that the catalytic activity of the mesoporous molecular sieves increases with increasing aluminium content. On the other hand , the deactivation of the lanthanum containing catalysts was lower. However, ZSM-5 was more active and showed only slight deactivation.
