| Abstract: | Catalyst A based on alumina and catalyst A+B which was based on alumina and mixed with elements of vice-fourth family were prepared. The performances of them were also studied. The comparison of activities of catalyst A,catalyst A+B and HZSM-5 molecular sieve catalyst was discussed. The results showed that under the conditions of temperature 300℃, space velocity 4.25～4.5h -1 and normal pressure, using catalyst A, the selectivity of dimethyl ether was more than 99% and the conversion of methanol was more than 80% |
