| Abstract: | Modification of NaZSM 5 by Li 2O and La 2O 3 was made.Characterication of modified NaZSM 5 by XRD and IR showed that addition of Li 2O cause the change of structure of ZSM 5 zeolite.The activity experiments results indicated that Li La/NaZSM 5 catalyst showed much better transeterification activities than NaZSM 5. |
