Abstract: PURPOSE: A catalyst for synthesis of dimethyl ether by dehydration reaction of methanol is provided to increase a lifetime of the catalyst, and to prevent hydrocarbon by-products due to high catalyst activity. CONSTITUTION: A catalyst for synthesis of dimethyl ether by dehydration reaction of methanol includes Hydrogen- or Ammonium- hydrophobic zeolite of 1 part by weight. The catalyst for synthesis of dimethyl ether includes an aluminum phosphate binder of 0.5 ~ 10 parts by weight. The catalyst for synthesis of dimethyl ether further includes a metal positive ion precursor selected from alkali metal and alkaline earth metal of 0.1 ~ 0.1 parts by weight.
