TiO_2改性的γ-Al_2O_3负载Cu催化剂上CO_2加氢合成甲醇的研究

The studies of methanol synthesis over the titanium-modified γ-alumina-supported CuO catalysts from CO_2 hydrogenation

在固定床高压微反装置上 ,系统研究了TiO2 改性的γ -Al2 O3 负载Cu催化剂的CO ,CO2 加氢反应 .活性评价结果表明 ,TiO2 的添加极大地促进了Cu/γ Al2 O3 催化剂的CO2 加氢合成甲醇反应的活性 ,但是对CO加氢合成二甲醚有抑制作用 ,这表明CO2 。

The titanium-modified γ-alumina-supported CuO catalysts have been prepared and used for methanol synthesis by CO 2 hydrogenation in high pressure micro-reactor. The results showed that the addition of TiO 2 was markedly promoted the activation of methanol synthesis by CO 2 hydrogenation,but restrained dimethyl ester synthesis by CO hydrogenation. That means that the hydrogenation of CO,CO 2 were essentially different.
