CATALYST FOR DIMETHYLETHER SYNTHESIS FROM SYNTHETHIC GAS METHOD FOR PREPARING THE SAME AND METHOD FOR PREPARING DIMETHYLETHER USING THE SAME

The present invention provides a method for preparing a catalyst for the synthesis of dimethylether from synthethic gas, which comprises the following steps of: preparing mesoporous ferrierite zeolite (FER); and preparing a hybrid CZA/mesoFER catalyst by coprecipitating a precursor of mesoporous ferrierite zeolite and Cu-Zn-Al-based oxide (CZA). An object of the present invention is to provide the catalyst capable of preparing the dimethylether from the synthethic gas, which has excellent catalytic activity and shows active mass transfer to increase reactivity, and has excellent conversion rate of carbon monoxide (CO) and the selectivity of dimethyl ether (DME). 본 발명은 메조포러스 페리어라이트 제올라이트(FER)를 제조하는 단계, 그리고 메조포러스 페리어라이트 제올라이트와 Cu-Zn-Al계 산화물(CZA)의 전구체를 공침시켜 하이브리드 CZA/mesoFER 촉매를 제조하는 단계를 포함하는, 합성가스로부터 디메틸에테르 합성용 촉매의 제조 방법을 제공한다.
