溶胶-凝胶法CuO-ZnO/SiO_2-ZrO_2超细微粒催化剂的研究

Study of Ultrafine Particle CuO-ZnO/SiO 2-ZrO 2 Catalysts

用溶胶－凝胶法制备了ＣｕＯ－ＺｎＯ／ＳｉＯ２－ＺｒＯ２超细催化剂，用ＸＲＤ、ＩＲ、ＴＰＲ、ＢＥＴ方法对其结构和性能进行了表征，并在固定床微型反应器上进行催化ＣＯ２加氢制甲醇性能的评价。结果表明，此催化剂具有较高的活性，甲醇选择性高。

In this paper, the ultrofine particle CuO-ZnO/SiO 2-ZrO 2 catalysts were prepared by sol-gel method, and were characterized by IR、BET、TPR and XRD Their catalytic performance of methanol synthesis from CO 2 and H 2 were evaluated in a micro-fixed bed reactor The result showed that the catalysts have high catalytic activity and high selectivity of methanol formation
