项目摘要

This Research in Undergraduate Institution project, supported jointly by the Analytical and Surface Chemistry Program of the Division of Chemistry and the Chemical Reaction Processes Program of the Division of Chemical and Transport Systems, focusses on the synthesis and characterization of molybdenum carbide and nitride catalysts for hydrodesulfurization chemistry. Synthesis of these materials and promotion by Co and Ni, evaluation by spectroscopic studies of adsorbed probe molecules such as CO and NO, and determination of HDS activity for a number of model feedstocks forms the range of studies being carried out by Professor Bussell and his students at Western Washington University. This work introduces undergraduates and masters degree students to state of the art research in heterogeneous catalysis, and provides important new information about the fundamentals of hydrodesulfurization catalysis on novel bimetallic systems. The removal of sulfur from crude oil and coal is an important application of heterogeneous catalysis. This hydrodesulfurization chemistry is the focus of this research project. Novel molybdenum carbide and molybdenum nitride catalysts are synthesized and characterized in this work, and the effect of Co and Ni promoters on the activity of these materials is evaluated. This work provides fundamental information for the design and preparation of important new catalytic systems.

该本科项目由化学系分析与表面化学项目和化学与运输系统系化学反应过程项目联合资助，重点研究用于加氢脱硫化学的碳化钼和氮化钼催化剂的合成和表征。这些材料的合成以及 Co 和 Ni 的促进、通过吸附探针分子（例如 CO 和 NO）的光谱研究进行评估以及确定多种模型原料的 HDS 活性构成了西华盛顿大学 Bussell 教授和他的学生正在进行的研究范围。这项工作向本科生和硕士生介绍了多相催化的最先进研究，并提供了有关新型双金属系统加氢脱硫催化基础知识的重要新信息。从原油和煤中脱硫是多相催化的重要应用。加氢脱硫化学是该研究项目的重点。本工作合成并表征了新型碳化钼和氮化钼催化剂，并评估了 Co 和 Ni 促进剂对这些材料活性的影响。这项工作为重要的新型催化系统的设计和制备提供了基础信息。
