RUI: Noble Metal Phosphide Catalysts for Deep Hydrodesulfurization

无机化学、生物无机化学和金属有机化学项目的这一奖项支持西华盛顿大学(WWU)的Mark E.Bussell教授和韦恩州立大学(WSU)的Stephanie L.Brock教授开发基于贵金属磷化物的高活性和耐硫加氢处理催化剂。贵金属磷化物催化剂的性能将被定制用于烷基取代的二苯并噻吩类化合物的深度加氢脱硫(HDS)；从原油中去除这些物种对于生产超低硫燃料至关重要。采用程序升温还原(TPR)法制备了贵金属分散在高比表面积二氧化硅上的单金属和双金属磷化物催化剂。这些催化剂将用各种对本体和表面敏感的物理化学技术进行表征，这些表征研究的主要目标是促进这些材料的本体和表面化学性质与其深度加氢脱硫催化性能的关联。为了更深入地了解TPR法制备的贵金属磷化物催化剂的催化性能，我们将对相同金属磷化物的氧化物负载、单分散的纳米颗粒进行平行研究。拟议的研究将建立和加强两名研究人员、他们的学生和太平洋西北国家实验室科学家之间的合作活动。本科生(和硕士水平)将参与WWU研究项目的所有方面，WSU的博士生也将参与。

This award of the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports the work of Professor Mark E. Bussell of Western Washington University (WWU) and Professor Stephanie L. Brock of Wayne State University (WSU) to develop highly active and sulfur resistant hydrotreating catalysts based on noble metal phosphides. The properties of the noble metal phosphide catalysts will be tailored for deep hydrodesulfurization (HDS) of alkyl-substituted dibenzothiophenes; the removal of these species from crude oil is crucial to the production of ultra-low sulfur fuels. Monometallic and bimetallic phosphide catalysts of noble metals dispersed on high surface area silica will be prepared using the temperature-programmed reduction (TPR) method. The catalysts will be characterized with a variety of bulk and surface sensitive physicochemical techniques, with the primary goal of these characterization studies being to facilitate correlation of the bulk and surface chemical properties of these materials with their deep HDS catalytic properties. To facilitate deeper understanding of the catalytic properties of the noble metal phosphide catalysts prepared via TPR, parallel studies will be carried out on oxide-supported, monodisperse nanoparticles of the same metal phosphides. The proposed research will build and strengthen collaborative activities between the two investigators, their students, and scientists at the Pacific Northwest National Laboratory. Undergraduate (and M.S. level) students will be involved in all aspects of the research project at WWU, as will be a doctoral student at WSU.
