Hydrogenation of Carbon Dioxide over Cu-Zn-Cr Oxide Catalysts

Article abstract of DOI:10.1246/bcsj.67.546

The hydrogenation of carbon dioxide for methanol synthesis was studied over Cu-Zn-Cr oxide catalysts, which were prepared by using CrO3 as a source of chromium.From the results of improving this type of catalysts, a catalyst prepared by the addition of copper-zinc carbonate to an aqueous solution of CrO3 was confirmed to be the most effective in this study.The detailed reaction behaviors, such as the dependence on the pressure, temperature and space velocity, were studied using this catalyst.
