PURPOSE:To obtain the title catalyst which suppresses reactions to produce by-products by precipitating a composite hydroxide of copper, zinc, and aluminum on a metal oxide or hydroxide carrier and stabilizing by sintering. CONSTITUTION:A composite hydroxide of copper, zinc, and aluminum as an active component for methanol synthesis is precipitated on an oxide or a hydroxide of aluminum, titanium, etc., having a methanol dehydration activity. Then, the precipitation product is filtered and sintered for stabilization. A catalyst prepared by this method accelerates methanol synthesis reaction and methanol dehydration reaction and suppresses by-product formation in the dehydration reaction in synthesis of dimethyl ether from CO and H2. |
