摘    要:用共沉淀法制备一步法合成二甲醚浆状催化剂的前躯体,完全液相热处理后,在浆态床中对其催化性能进行了测试,通过XRD、BET和元素分析对其进行了表征。结果表明,将Zr组分引入CuZnSiAl催化剂后,催化剂二甲醚的选择性提高。

关 键 词:二甲醚  Cu基催化剂  浆态床  完全液相法  共沉淀

Abstract:A series of bifunctional catalyst's precursors were prepared by coprecipitation and then treated with complete liquid-phase technology.The catalytic performance was evaluated in a slurry reactor.The catalysts were characterized by means of XRD,BET and elemental analysis.The results showed that the addition of Zr improved DME selectivity.
Keywords:dimethyl ether(DME)  Cu-based catalyst  slurry reactor  complete liquid-phase technology  coprecipitation
