Sulfated zirconia (SZ) and two promoted 1％Mn/SZ catalysts which have been prepared via sol gel (Mn/SZ-S) and impregnation (Mn/SZ-I) methods were studied. The morphology of the catalysts was characterized by XRD, BET, NH3-TPD, ICP, SEM and FT-IR analysis. The conversion of methanol to dimethyl ether and hydrocarbons was carried out in the temperature range of 120-300 °C. The Mn/SZ-S showed the highest activity due to the high surface area with suitable acidity. The optimum condition of Mn/SZ-S catalyst was investigated at 200 °C and LHSV of 0.02 h-1 in a time range from 30 to 210 min. It was found that the total conversion decreased from 80.18％ to 53.26％ at 210 min. The reusability of this catalyst was studied at the optimum condition up till four cycles for 1 h. The characterization of the reused catalyst showed a significant change in the structure and surface acidity due to the blockage of the surface acid sited by carbonaceous materials.
