采用微流控连续共沉淀法制备了CuO-ZnO-ZrO2催化剂。然后研究了CO2加氢制甲醇的催化行为，并与相同Cu-0（30%）用量的经典共沉淀法制备的CuO-ZnO-ZrO2催化剂进行了比较。新的合成方法使催化剂具有更好的重复性和均匀性，在280℃，50 bar和10,000 h（-1）的GHSV下，甲醇的最佳产率为486 g(MeOH) kg(cata) (-1) h（-1）。(C) 2015 Elsevier B.V.版权所有
A new method of synthesis based on micro-fluidic continuous coprecipitation has been used to prepare CuO-ZnO-ZrO2 catalyst. The catalytic behavior was then investigated for CO2 hydrogenation into methanol and compared with a CuO-ZnO-ZrO2 catalyst prepared by classical coprecipitation and with the same amount of Cu-0 (30%). The novel synthesis method allows a better repeatability and homogeneity of the catalyst which leads to the best methanol productivity of 486 g(MeOH) kg(cata) (-1) h(-1) at 280 degrees C under 50 bar and a GHSV of 10,000 h(-1).
