| 摘 要： | 采用热分析方法对CuO-ZnO-Al2O3和CuO-ZnO-CrOx-Al2O3催化剂的前驱体进行了研究，结果表明，当铬元素以硝酸铬引入时，Cr(NO3)3与碳酸钠反应生成Cr(OH)3沉淀，沉淀物的热分解产物为Cr2O3。当Cr元素采用Na2CrO4引入时，沉淀物的热分解产物为CrO3和CuO3。

| Abstract: | The precursors of CuO ZnO Al 2O 3 and CuO ZnO CrO X Al 2O 3 catalysts were studied by thermoanalysis method. The results show that the precipitate decomposition product is Cr 2O 3 when chromium element is imported by Cr(NO 3) 3 and the latter is precipitated by Na 2CO 3; when chromium element is imported by Na 2CrO 4, the precipitate decomposition product is CrO 3. |
