| Abstract: | The process conditions for producing high purity DME of aerosol grade by catalytic dehydration of methanol in gas phase were studied and tested by using alumina as a catalyst.Methanol conversion,DME selectivity and DME mass fraction respectively are 60%～70%,99% and 99 9% at 280～330 ℃ and under 0 8 MPa. A 2 000 t/a plant based on this process has been successfully operated with production of qualified product. |
