Zeolite-Supported Ruthenium Catalysts for Carbon Monoxide Hydrogenation Reaction

建议标题：沸石负载的Ru催化剂用于一氧化碳加氢反应建议编号：CTS-0000485首席研究员：Jale Akyurtluu研究所：汉普顿大学该项目的目标是使用一种新的催化剂体系由碳和氢的氧化物合成碳氢化合物。Fischer-Tropsch(FT)合成是合成气转化为汽油、柴油、蜡和醇的一条实用路线。由于合成了一系列产品，低品位馏分的产品分离和升级限制了FT合成的商业应用。对在合成氨反应中取得成功的碱土负载、金属促进沸石负载的Ru簇合物进行了评价和表征。需要研究的问题包括金属颗粒大小和位置的影响、金属的可还原性、金属与沸石的相互作用、阳离子类型和浓度效应、孔结构影响和酸度效应。还将对FT合成进行机理研究。该项目将涉及汉普顿大学的本科生，并将与弗吉尼亚大学合作执行。由于在过去20年中，已建立的天然气储量比石油储量有所增加，因此可能会发生将天然气作为燃料和合成的重要原料的转变。如果成功，这项工作将有助于设计新的催化剂，用于生产有价值的化工产品。

AbstractProposal Title: Zeolite-Supported Ruthenium Catalysts for Carbon Monoxide Hydrogenation ReactionsProposal Number: CTS-0000485Principal Investigator: Jale AkyurtluInstitution: Hampton University The objective of this project is to use a novel catalyst system in the synthesis of hydrocarbons from the oxides of carbon and hydrogen. The Fischer-Tropsch (FT) synthesis is a practical route for the conversion of synthesis gas to gasoline, diesel oil, wax and alcohols. Because an array of products is synthesized, the product separation and upgrading of lower-grade fractions limit the commercial application of FT syntheses. Ruthenium clusters supported on alkali earth, metal-promoted zeolites, which have been successful in ammonia synthesis, will be evaluated and characterized. Issues to be investigated include metal particle size and location influences, metal reducibility, metal-zeolite interactions, cation type and concentration effects, pore structure influences, and acidity effects. A mechanistic study of the FT synthesis will also be performed. This project will involve undergraduates from Hampton University and will be performed in collaboration with the University of Virginia. Because established gas reserves have increased over oil reserves in the past two decades, a shift towards gas as an important feedstock for fuels and syntheses may occur. If successful, this work will aid in the design of new catalysts for the production of valuable chemical products.
