中国科学院福建物质结构研究所于2009年首次实现了第一代煤制乙二醇催化剂的产业化。但是,目前的催化剂还存在着许多有待改进的地方,如酯加氢催化剂中贵金属负载量高、铬的毒性大等。为了改进催化剂,我们对催化剂的纳米结构进行了系统深入的研究,揭示了催化剂的小面效应、尺寸效应、协同效应、载体效应等,开发了一系列催化剂制备技术,实现了贵金属的高效利用。脱氢催化剂和CO氧化偶联催化剂的Pd负载量分别从2.5%和2.0%降到0.9%和0.13%,但催化性能有较大提高。将酯类加氢催化剂中有毒的铜铬改质为绿色铜硅。成功开发了具有自主知识产权的先进的新型煤制乙二醇催化剂。
Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences has achieved the industrialization of the first generation catalysts for coal to ethylene glycol for the first time in 2009. However, there are still lots of aspects to be improved, such as high noble metal loading and toxic Cr in catalyst of ester hydrogenation. To improve the catalysts, we have done systematic deep research about the nanostructures of catalysts, and revealed facet effect, size effect, synergistic effect, support effect, and so on. A series of catalysts preparation technologies have been developed to achieve the efficient utilization of noble metals. The Pd loadings of dehydrogenation catalyst and CO oxidative coupling catalyst have been dropped from 2.5% to 0.9% and 2.0% to 0.13%, respectively, while the catalytic performances are enhanced greatly. The toxic Cu-Cr in ester hydrogenation catalyst has been upgraded to green Cu-Si. The new catalysts for coal to ethylene glycol with advancement have been successfully developed with independent intellectual property rights.
