Book Description
This book is a guide to kinetic studies of reaction mechanisms. It reviews conventional reactor types and data collection methods, and introduces a new methodology for data collection using Temperature Scanning Reactors (TSR). It provides a theoretical and practical approach to temperature scanning (TS) methodology and supports a revival of kinetic studies as a useful approach to the fundamental understanding of chemical reaction mechanisms and the consequential reaction kinetics.·Describes a new patented technology·Of interest to industrial and academic researchers in the fields of kinetics and catalysis·No existing competitor for this title

Book Description
This volume contains peer-reviewed manuscripts describing the scientific and technological advances presented at the 6th Natural Gas Conversion Sumposium held in Alaska in June 2001. This symposium continues the tradition of excellence and the status as the premier technical meeting in this area established by previous meetings.The 6th Natural Gas Conversion Symposium is conducted under the overall direction of the Organizing Committee. The Program Committee was responsible for the review, selection, editing of most of the manuscripts included in this volum. A standing International Advisory Board has ensured the effective long-term planning and the continuity and technical excellence of these meetings.

Book Description
In der vorliegenden Arbeit wurde die heterogen katalysierte Oxidation von Ethen zu Ethylenoxid an Silberkatalysatoren untersucht. Ziel dieser Arbeit war es, Mikrostrukturreaktoren für schnelle und stark exotherme Oxidationsreaktionen zu erproben und diese Epoxidation diente als Modellreaktion. Gleichzeitig wurden explosions- und flammhemmende Eigenschaften des Mikrostrukturreaktors ausgenutzt, um die partielle Oxidation von Ethen zu Ethyenoxid im Explosionsbereich (> 9% Sauerstoff) ohne Sicherheitsprobleme zu ermöglichen. Um die gesteckten Ziele zu erreichen wurden zwei parallele Lösungswege beschritten. Zunächst wurden modulare Mikrostrukturreaktoren und geeignete mikrostrukturierte Katalysatorträger entwickelt, um Untersuchungen verschiedener katalytischer Beschichtungen in dieser neuen und nicht allgemein verfügbaren Reaktorbauweise zu ermöglichen. Zur katalytische Erprobungen dieser Konstruktion war es notwendig, geeignete Beschichtungstechniken zur Immobilisierung katalytisch aktiver Spezies zu entwickeln. Durch die Bauweise dieser Reaktoren als Wandreaktor erschien es anfänglich nicht möglich, kommerziell verfügbare pellet-artige Katalysatoren zu verwenden. Daher wurden, parallel zur Konstruktion der modularen Mikroreaktoren, verschiedene auf Silber basierende Beschichtungstechniken hinsichtlich ihrer Eignung für diese Reaktion erprobt. Zur Erprobung kamen u.a. Silberimmobilisierung in einem durch anodischen Oxidation erzeugen Porensystem bzw. einer durch Sol-Gel Beschichtung erzeugten a-Aluminiumoxid Schicht und die Abscheidung von metallischem Silber per Vakuumbeschichtung auf einem Trägermaterial. Zuletzt wurde die Immobilisierung eines gemahlenen, kommerziellen Katalysators per elektrostatischer Pulverabscheidung auf einem entsprechend präparierten Trägermaterial vorgenommen und erfolgreich erprobt. Die wichtigste Erkenntnis dieser Arbeit aus chemisch-katalytischer Sicht ist der enorm positive Einfluss hoher Sauerstoffkonzentrationen auf die Selektivität u.

Book Description
Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
