Objective:

The goal of this project is the linking of microkinetic analysis and computational chemistry to investigate the reactivities of hydrocarbons over both solid-acid catalysts and supported-metal catalysts.

Progress Summary:

This project is part of a long-range research campaign to develop principles for the rational design of economically and environmentally sustainable catalytic reactions. The campaign involved two phases: 1) the development of the field of microkinetics of heterogeneous catalysis to elucidate the essential catalytic chemistry of existing heterogeneous catalysts and 2) the application of principles of computational chemistry to explore for new and improved catalysts.

The field of microkinetic analysis is now well established and has been successfully demonstrated in collaborative research projects with 1) CenCITT and Engelhard Corporation on catalytic cracking and 2) CenCITT, EPA-RRL and National Science Foundation on catalytic dehydrogenation. With the advent of better software and the increased availability of supercomputers, it is now possible to describe larger chemical ensembles using computation chemistry techniques. This research seeks to further develop the linking of microkinetic analysis and computational chemistry and use the resulting principles for the rational design of new catalyst systems.

The strategy of our approach involves the combination of results from spectroscopic, microcalorimetric, kinetic, and quantum chemical studies to study the reactivities of hydrocarbons over solid-acid catalysts and supported metal catalysts. Structural, chemical, and catalytic information about the catalytic sites are obtained from the combination of results from spectroscopic, microcalorimetric, and kinetic studies.

Results from these experimental investigations can be complemented with quantum chemical calculations, based on density functional theory (DFT), to first predict the observed energetic and spectroscopic results and then extend the results to predict the bond energies of reactive intermediates and transition states that cannot be measured directly. Microkinetic analysis provides a method to interpret, coordinate, and generalize results from these diverse experimental and theoretical studies to create a basis for quantitative description of catalytic surface chemistry. The resulting quantitative model allows the elucidation of the chemical properties of catalytic sites and the role of these sites in catalytic processes.

We have conducted numerous theoretical investigations based on DFT calculations to supplement the results of our experimental investigations. We have reported the combined results of these theoretical and experimental investigations in a number of publications. We have published work probing the role of carbenium ions in the isomerization of butanes and 2-methyl-pentene-2 over solid-acid materials as well as the interactions of alcohols, acetates, and acetaldehyde with silica.

Furthermore, we have extended this combined approach to investigate the interaction of carbon monoxide and light hydrocarbons over transition metals. Additionally, we have published several papers from our continued microkinetic analyses of the cracking reactions over solid-acid USY cracking catalyst and hydrogenation/ dehydrogenation of light hydrocarbons over Pt/Sn-based materials.

In this work we are collaborating with UOP Inc., Des Plaines, IL, in the characterization of solid acid catalysts. In addition, UOP has supplied us with a number of industrial solid-acid material such as silica-alumina, chlorinated alumina, and ferrierite. Furthermore, we have continued our association with Ross Madon of Engelhard Corporation for the investigations of hydrocarbon reactions over solid-acid catalysts.
