PURPOSE: A methanol dehydration catalyst and a manufacturing method of the same are provided to improve the yield of dimethyl ether by preventing the generation of byproducts such as low grade hydrocarbon. CONSTITUTION: A method dehydration catalyst is made of an amorphous compound. The amorphous compound is represented by Si_xAl_yP_zO_m. The specific surface area of the methanol dehydration catalyst is more than or equal to 50m^2/g. In the chemical formula, x/y is in a range between 0.001 and 1.2; z/y is in a range between 0.5 and 1.5; and m is 2x(x+y+z). The volume of microspores, of which diameters are less than 3500nm, in the methanol dehydration catalyst is more than or equal to 0.3cc/g. [Reference numerals] (AA) Intensity |
