甲醇脱氢催化剂的研究

Study on the Catalysts of Methanol Dehydrogenation

利用固定床反应器，研究了铜系催化剂对甲醇脱氢合成甲酸甲酯的催化性能。试验结果表明，Ｃｕ－ＺｎＯ－ＺｒＯ＿２／ＳｉＯ＿２，催化剂具有较高的活性，在适宜的反应条件下，甲酸甲酯的产率在２０％以上，用ＸＲＤ测试对催化剂表面物相进行了表征分析。

The dehydrogenation of metbanol to methyl formate in a fixed-bed reactor with Cu catalystscontaining Zn and Zr supported on SiO_2 was studied. The catalyst Cu-ZnO-ZrO_2 /SiO_2 showedhigher activity and selectivity. The yield of methyl formate is over 20%under suitable condi-tions. The Catalysts were characterized by X-ray diffraction.
