Abstract LaCoO3 samples were obtained by the hydrothermal and citrate methods. The dynamics of the phase transformations of the initial hydroxo compounds into the oxide state and the subsequent reduction in a hydrogen-containing mixture were studied by the differential thermal analysis and X-ray diffraction methods. The results of the catalytic tests in the syngas conversion showed that the path of conversion depends on the phase composition of the catalyst in the oxide state. In contrast to the standard CoAl sample, alcohols prevail in the liquid products formed on LaCoO3 catalysts.

LaCoO3 钙钛矿型催化剂在合成气转化中的应用

摘要 LaCoO3 样品是通过水热法和柠檬酸盐法获得的。通过差热分析和 X 射线衍射方法研究了初始羟基化合物到氧化物状态的相变动力学以及随后在含氢混合物中的还原。合成气转化中的催化试验结果表明，转化路径取决于处于氧化物状态的催化剂的相组成。与标准 CoAl 样品相比，在 LaCoO3 催化剂上形成的液体产品中，醇类占优势。
