Synthesis, Characterization and Evaluation of Promoted Molybdenum Carbide and Nitride Hydrodesulfurization Catalysts

本项目由化学学部分析与表面化学项目和化学与传输系统学部化学反应过程项目联合支持，重点研究碳化钼和氮化钼加氢脱硫化学催化剂的合成和表征。这些材料的合成和Co和Ni的促进，通过吸附探针分子（如Co和NO）的光谱研究进行评估，以及确定许多模型原料的HDS活性，构成了Bussell教授和他在西华盛顿大学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新研究进展，并为新型双金属体系加氢脱硫催化的基本原理提供了重要的新信息。原油和煤中硫的脱除是多相催化的一个重要应用。加氢脱硫化学是本课题研究的重点。本文合成并表征了新型碳化钼和氮化钼催化剂，并评价了Co和Ni促进剂对材料活性的影响。这项工作为设计和制备重要的新型催化体系提供了基础信息。

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.
