摘　　要：研究高能球磨技术对浸渍法制备CuCo/ZrO_2催化剂结构与合成低碳醇性能的影响,借助N_2吸附-脱附等温线、扫描电镜、X射线衍射和程序升温还原等测试技术对催化剂进行表征,并以CO加氢合成低碳醇为模型反应对其催化性能进行评价。研究结果表明,催化剂制备过程中引入高能球磨技术可显著提高CuCo/ZrO_2催化剂的CO转化率和C_2^+OH选择性。The catalytic properties of high-energy ball-milled CuCo/ZrO2 catalysts for the synthesis of higher alcohols from syngas and the effects of high-energy ball-milling method on the structure and perfommnce of the catalysts were investigated. The catalysts were characterized by means of BET, SEM, XRD and H2-TPR techniques. The results indicated that CO conversion and selectivity to C2^＋ OH were enhanced significantly when the high-energy ball-milling method was used in the process of the catalyst preparation.
