一种合成低碳醇的催化剂及其制备方法
摘要：
本发明提供一种合成低碳醇催化剂及制备方法。所述的催化剂为双层包覆结构，内核为惰性瓷球、外层为包覆有惰性氧化铝的活性组分；其中，活性组分中的金属组元用CuaFebZnc表示，式中a、b、c分别为Cu、Fe、Zn元素的原子比，a＝1，b＝0.1-1，c＝0.1-1；活性组分中包覆的惰性氧化铝占活性组分的重量百分比在70％-95％之间；所述的活性组分占催化剂的重量百分比在20-60％之间。本发明催化剂的制备方法为：由Cu-Fe-Zn组成的金属组元包覆于尺寸为10-50微米的氧化铝粉体上，制成活性组分；活性组分经涂覆成型，再包覆于尺寸3-5mm的惰性瓷球上。与传统催化剂相比，采用本发明制备的催化剂，所制备的催化剂具有高催化活性和高C2+醇选择性，而且催化剂性能稳定，具有较长使用寿命。
摘要（英）：

The invention provides a catalyst for synthesizing low carbon alcohol, and a preparation method thereof. The catalyst is a double-layer cladding structure, the core is an inert porcelain ball, and the external layer is an active component coated with inert alumina, wherein metal constituent element in the active component is represented by CuaFebZnc, a, b and c in CuaFebZnc respectively are the atomic ratio of Cu, Fe and Zn elements, a is 1, b is 0.1-1, and c is 0.1-1; the coated inert alumina in the active component accounts for 70-95% of the weight of the active component; and the active component accounts for 20-60% of the weight of the catalyst. The preparation method of the catalyst comprises the following steps: coating alumina powder with the dimension of 10-50[mu]m with the metal constituent composed of Cu-Fe-Zn to prepare the active component; and carrying out coating molding on the active component, and coating the inert porcelain ball with the dimension of 3-5mm with the molded active component. Compared with traditional catalysts, the catalyst prepared in the invention has the advantages of high catalysis activity, high C2+ alcohol selectivity, stable performances and long service life.
