| Abstract: | The catalyst of SO4^2-/TiO2 was prepared by sol-gel method. The catalyst was soakag with different concentrations of sulfuric acid, the activity of catalyst was discussed and the optimal catalyst was chosen. Then effects of the reaction temperature and methanol flow on the performance of the catalyst and the reason for the deactivation of the cata- lyst were studied. The experiment results show that the activity of catalyst S10 was the best, the MTO reaction tempera- ture was 410 - 430 ℃ with 98.8% methanol conversion and 90.65% selectivity of ethylene, the methanol flow rate was 0.05tool. s^-1. |
