Development of Solid State NMR Methods for the Study of Catalyst Reactivity and Deactivation

这项拨款是在分析和表面化学的一般领域和催化表面化学的核磁共振研究的子领域。James M. Haw教授将开发和利用核磁共振方法研究石油和化学加工中使用的多相催化剂。特别地，就地检查化学反应的方法将用于跟踪反应的产物和在进行中的反应中形成的中间物质。采用原位高场固体魔角自旋核磁共振方法研究催化反应性和失活性。沸石催化剂和负载型金属催化剂将在碳氢化合物和甲醇的反应之后进行研究，以及焦化对反应过程中和反应后形成的物质结构的影响。

This grant is in the general area of analytical and surface chemistry and in the subfield of nuclear magnetic resonance studies of catalytic surface chemistry. Professor James M. Haw will develop and utilize nuclear magnetic resonance methods for the study of heterogeneous catalysts used in petroleum and chemical processing. In particular, methods to examine the chemical reactions in-situ will be utilized to follow both the products of reactions and intermediate species formed during ongoing reactions. Catalytic reactivity and deactivation will be studied with in-situ high field solid state magic angle spinning nuclear magnetic resonance methods. Both zeolite catalysts and supported metal catalysts will be examined following the reactions of hydrocarbons and methanol and the effects of coking on the structure of species formed during and after reaction.
