| Abstract: | Ferrierite（FER） was modified with Zn,Mn while γ-Al2O3 was modified with S2O2-8 and Ni2＋.The composite of modified FER and γ-Al2O3 was used as the dehydrating agent to prepare the Cu-Zn-Al/ASN/FZM bifunctional catalyst for the direct preparation of dimethyl ether from syngas.Effects of modification conditions,composite ratio and reaction temperature on the performance of the catalysts were studied in a continuous high pressure fixed bed reactor.The best catalytic performance was archived at 240℃,3.2MPa,1500h-1 while the molar ratio of H2/CO was 2.80% conversion of CO and 75% selectivity toward dimethyl ether were thus obtained.The catalytic performance of the composite catalyst is better than that when the modified FER or γ-Al2O3 was solely used. |
