The vapour phase catalytic hydrogenation of benzaldehyde to benzyl alcohol using copper supported Magnesium-Alumina (Mg-Al) hydrotalicite (CuHT) catalyst was studied. The effect of various copper metal loadings, reaction temperature and different preparatory methods on the activity of catalysts was determined. A better catalytic performance was observed for 12.5CuHT catalyst prepared by impregnation method at 250 °C. The maximum conversion of about 68% with 93% benzyl alcohol selectivity was obtained at the optimized conditions. The catalyst was active upto 87 h with time-on-stream. The activity of CuHT was influenced by high surface area, smaller crystallite size and weak metal support interaction.

Cu负载的Mg-Al水滑石催化剂将苯甲醛气相选择性加氢制为苯甲醇

研究了使用铜负载的镁铝(Mg-Al)水滑石(CuHT)催化剂将苯甲醛气相催化氢化为苯甲醇。确定了各种铜金属负载量,反应温度和不同的制备方法对催化剂活性的影响。在250°C下通过浸渍法制得的12.5CuHT催化剂具有更好的催化性能。在优化的条件下获得了约68%的最大转化率和93%的苄醇选择性。随着运行时间的延长,催化剂的活性长达87小时。CuHT的活性受高表面积,较小的微晶尺寸和弱的金属载体相互作用的影响。
