用于己二酸二甲酯制己二醇的催化剂及其制备方法和应用
摘要：
本发明公开了种用于由己二酸二甲酯制备1,6‑己二醇的催化剂,该催化剂的组成为Cu‑Zn‑Al‑Zr氧化物,该催化剂的原子比为Cu:25~60,Zn:25~50,Al:10~30,Zr:0.15~1.2。本发明还公开了种上述催化剂的制备方法。本发明提供的催化剂的活性和耐热性好,同现有技术相比,该催化剂还原温度较低,为200~220℃,可以直接在反应器内还原,节约成本;该催化剂使用时,降低了反应压力(5~8MPa),提高了空速,最终能够降低己二醇的生产成本,且制备方法简单,无需额外的特殊设备,具有较好的应用前景。
摘要（英）：

The invention discloses a catalyst for preparing 1,6-hexanediol from dimethyl adipate.The catalyst is composed of a Cu-Zn-Al-Zr oxide, and comprises 25-60% of Cu, 25-50% of Zn, 10-30% of Al and 0.15-1.2% of Zr.The invention further discloses a preparation method of the catalyst.The catalyst is good in activity and heat resistance.Compared with the prior art, the reduction temperature of the catalyst is low and is 200-220 DEG C, the catalyst can be directly reduced in a reactor, and the cost is reduced; when the catalyst is in use, reaction pressure is reduced to 5-8 MPa, the air speed is decreased, and finally the production cost of hexanediol can be reduced; the preparation method is simple, no additional special equipment is needed, and the application prospect is good.
