Book excerpt: This project studied the heterogeneous catalytic reaction of carbon monoxide and oxygen on the surface of thin platinum metal films to form carbon dioxide. Infrared imaging was used to study both the spatial and temporal behavior of the reaction. The mechanisms of spatial coupling in this system were studied as well as their effect on the resulting pattern formation. A complementary study was conducted to examine the effect of local perturbations in initiating catalytic behavior. An important conclusion of the work is that, while none of the currently proposed models completely describes the oscillatory catalytic behavior observed in this system, the oxidation-reduction model agrees best with the experimental results.

Book Synopsis Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis by : G.F. Froment

Download or read book Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis written by G.F. Froment. This book was released on 1997-09-03. Available in PDF, EPUB and Kindle. Book excerpt: Many processes of the chemical industry are based upon heterogeneous catalysis. Two important items of these processes are the development of the catalyst itself and the design and optimization of the reactor. Both aspects would benefit from rigorous and accurate kinetic modeling, based upon information on the working catalyst gained from classical steady state experimentation, but also from studies using surface science techniques, from quantum chemical calculations providing more insight into possible reaction pathways and from transient experimentation dealing with reactions and reactors. This information is seldom combined into a kinetic model and into a quantitative description of the process. Generally the catalytic aspects are dealt with by chemists and by physicists, while the chemical engineers are called upon for mechanical aspects of the reactor design and its control. The symposium "Dynamics of Surfaces and Reaction Kinetics in Heterogeneous Catalysis" aims at illustrating a more global and concerted approach through a number of prestigious keynote lectures and severely screened oral and poster presentations.

Book excerpt: Present day heterogeneous catalysis is rapidly being transformed from a technical art into a science-based technology. A major contribution to this important change is the advance of surface spectroscopic techniques able to characterize the complex surfaces of the heterogeneous catalytic system. The Advanced Study Institute (on which the current proceedings is based) has as its primary aim the bringing together of a variety of lecturers, outstanding in those fields of experience, to enable a broad coverage of different relevant approaches. Not only catalyst characterization but also catalytic reactivity had to be covered in order to relate catalyst properties with catalyst performance. Since modern catalysis relates catalytic performance to microscopic molecular catalyst features, theoretical electronic aspects also had to be included. The Advanced Study Institute had a unique feature in that it brought together physicists, catalytic chemists and chemical engineers whom rarely directly interact. From physics especially new experimental possibilities of beams were emphasized. At present it is possible to obtain very detailed information on model catalysts, whilst the applications to practical catalysts are gaining rapidly in sophistication. Apart from the plenary lectures, the Institute included "hot topics" to highlight special developments and offered participants the opportunity to present contributed papers (either orally or as a poster). These contributions formed an integral part of the summer school and significantly enhanced the interaction between participants. Inclusion of the hot topics and contributed papers in these proceedings give them an added topical value.
