摘要
磷化钨(WP)催化剂具有优异的加氢精制活性和抗硫中毒性能。本文综述了WP加氢精制催化剂的晶体结构、加氢反应路径、制备方法、载体选用及添加助剂改性等方面的研究进展。阐述了活性组分负载方式及还原方式对催化剂性能的影响,并对单一氧化物载体和复合氧化物载体催化剂的性能进行比较,介绍了添加过渡金属或螯合剂对提高催化活性的作用。指出目前对WP催化剂加氢精制机理研究相对薄弱,进一步探究WP催化剂中各组分之间的作用机理、提高催化剂的加氢活性是未来的研究方向。
WP catalyst has an excellent hydrofining activity and property of anti sulfur poisoning. This article summarizes research progress in the crystal structure of WP hydrotreating catalyst, hydrogenation reaction path, preparation methods, carrier selection and adding additives modification. This paper expounds the effect of active component load mode and restore mode on the performance of catalyst. Catalyst performances with single oxide carrier and compound oxide carrier were compared. The article also introduced that the effect of catalytic activity can be improved by adding transition metals or chelating agent. Current research on the mechanism of hydrofining catalysis by WP is relatively weak, and further exploration of the affecting mechanism among components in WP catalysts, improvement of the activity of hydrogenation catalysts should be focused in future study.
