| 摘要 |
<p>The present invention relates to a catalyst for direct-synthesizing dimethyl ether from synthesis gas comprising 2-10 wt% of ferrierite pretreated with alumina based on 100 wt% of ferrierite and CuO-ZnO-Al_2O_3 oxides and a preparation method thereof. If performing reaction using the catalyst of the present invention, dimethyl ether can be produced by using synthesis gas having various range of H_2/CO ratio and especially production of by-products is inhibited thereby improving yield of dimethyl ether and stability of the catalyst so as to effectively synthesize dimethyl ether from synthesis gas.</p> |
