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。
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.
