摘要
Abstract
The H-MOR zeolite catalysts were prepared by hydrothermal synthesis. An inactivated catalyst which was used in dimthyl ether carbonylaiton was regenerated. The effects of gas, coke-burning temperature, O2 volume fraction and heating rate on the coke-burning process were investigated. The results of TPO and XRD analysis showed that there was different property coke on the inactivated catalyst. In the optimum conditions for the coke-burning of the inactivated catalyst, temperature 550℃, heating rate of 2℃·min?1 and O2 volume fraction of 3%,the catalyst activity was almost completely restored. The fresh and regenerated catalysts were characterized by means of NH3-TPD and N2 adsorption-desorption. The results showed that the coke was removed cleanly and channels were protected in the optimum condition.关键词
