运用ＸＲＤ、ＴＰＲ、Ｈ２－ＴＰＤ等表征手段考察了Ｃｕ－Ｍｎ催化剂的物相结构、氢气的还原性能及Ｈ２的吸附性能；在高压微反色谱系统中进行了ＣＯ加氢合成二甲醚的研究并和表征结果相关联。评价结果表明，Ｃｕ－Ｍｎ双组分催化剂对一氧化碳具有很高的活性及二甲醇的选择性； ＸＲＤ测定结果表明， Ｍｎ的存在使得ＣｕＯ的分散度提高：ＴＰＲ结果表明，锰的存在阻碍了ＣｕＯ的还原，ＣｕＯ存在能够促进ＭｎＯｘ的还原，双组分催化剂的还原并不是单组分催化剂的简单叠加，说明在催化剂的制备过程中ＣｕＯ和ＭｎＯｘ之间发生了一定的相互作用。Ｈ２的脱附实验表明，Ｍｎ的添加增强了催化剂对Ｈ２的吸附能力。
The phase structure of the Cu-Mn catalyst, the reduction performance of hydrogen and the adsorption performance of H2 were investigated by XRD, TPR and H2-TPD methods. The synthesis of dimethyl ether by CO hydrogenation was carried out in a high pressure micro-chromatographic system And associated with the characterization results. The results show that the Cu-Mn two-component catalyst has high activity for carbon monoxide and selectivity for methanol. The XRD results show that the presence of Mn increases the dispersion of CuO. The results of TPR show that the presence of Mn hinders CuO , The presence of CuO can promote the reduction of MnOx. The reduction of two-component catalyst is not a simple superposition of one-component catalysts, indicating that there is a certain interaction between CuO and MnOx during the preparation of the catalyst. H2 desorption experiments showed that the addition of Mn enhanced the ability of the catalyst for H2 adsorption.
