alkali alumina metasomatism

The Cu-based catalyst(500 g) for methanol synthesis was prepared by an acid-alkali alternate precipitation method.

采用酸-碱交替沉淀法制备了Cu基甲醇合成催化剂放大样(500 g),并用X射线衍射、低温N2吸附和扫描电子显微镜等对催化剂进行了表征,系统考察了制备条件(搅拌速度、溶液滴加速度、盐和碱溶液浓度等)对催化剂性能的影响。

The result of the research shows the best coagulating reagent is alkaline aluminium chloride, the best mixed concentration is 0.

最佳混凝剂为碱铝 ,最佳投药量为 0 。
