Abstract

In dieser Arbeit wurden technische Zeolithkatalysatoren (ZSM-5 + Binder) mittels Extrusion hergestellt und im Festbett-MTO-Prozess (Methanol-to-Olefins) getestet. Das Ziel war die Optimierung der Reaktionsbedingungen und des Katalysators, um möglichst hohe Selektivitäten zu Ethen und Propen sowie verbesserte Katalysatorstandzeiten zu erreichen.

Abstract

Ziel dieser Arbeit war es ein formalkinetisches Reaktionsmodell für den MTO-Prozess an AlPO4-gebundenen ZSM-5-Extrudaten zu erstellen. Dazu wurde eine Prozessstudie unter typischen MTO-Prozessbedingungen durchgeführt sowie ausgewählte Olefine einzeln und zusammen mit Methanol zudosiert. Anhand der experimentellen Daten konnte ein geeignetes Reaktionsnetz abgeleitet und ein Modell der Reaktionskinetik entwickelt werden.

Abstract

This second edition assesses some of the major refinements, extensions, and useful applications that have developed in neoinstitutionalist thought in recent years. More attention is given to the overlap between the New Institutional Economics and developments in economic history and political science. In addition to updated references, new material includes analysis of parallel developments in the field of economic sociology and its attacks on representatives of the NIE as well as an explanation of the institution-as-an-equilibrium-of-game approach. Already an international best seller, Institutions and Economic Theory is essential reading for economists and students attracted to the NIE approach. Scholars from such disciplines as political science, sociology, and law will find the work useful as the NIE continues to gain wide academic acceptance. A useful glossary for students is included. Eirik Furubotn is Honorary Professor of Economics, Co-Director of the Center for New Institutional Economics, University of Saarland, Germany and Research Fellow, Private Enterprise Research Center, Texas A&M University. Rudolph Richter is Professor Emeritus of Economics and Director of the Center for New Institutional Economics, University of Saarland, Germany.

Abstract

Microporous zeolites and nanoporous materials are important from an academic and industrial research perspective. These inorganic materials have found application as catalysts in several industrial processes in oil refinery, petro-chemical reactions, fine chemicals, speciality, drug discovery and pharmaceutical synthesis, exhaust emission control for stationary and mobile engines and industrial wastewater treatment. The reasons for their versatile applications in several industrial processes are their unique properties of microporous zeolites and nanoporous materials such as uniform pores, channel systems, shape selectivity, resistance to coke formation, thermal and hydrothermal stability. Furthermore, the possibility to tune the amount and strength of Brønsted and Lewis acid sites and their crystal size, as well as the possibility of modification with transition and noble metals, are key to their success as efficient, high selectivity and stable catalysts.

Abstract

Kinetics and reactor modeling for heterogeneous catalytic reactions are prominent tools for investigating and understanding catalyst functionalities at nanoscale and the related rates of complex reaction networks. This book illustrates some examples related to the transformation of simple to more complex feedstocks, including different types of reactor designs, i.e., steady-state, transient plug flow reactors, and TAP reactors for which there is sometimes a strong gap in the operating conditions from ultra-high-vacuum to high-pressure conditions. In conjunction, new methodologies have emerged, giving rise to more robust microkinetics models. As exemplified, they include the kinetics and the dynamics of the reactors and span a large range of length and time scales. The objective of this Special Issue is to provide contributions that can illustrate recent advances and novel methodologies for elucidating the kinetics of heterogeneous reactions and the necessary multiscale approach for optimizing the reactor design. This book is dedicated to postgraduate and scientific researchers, and experts in heterogeneous catalysis. It may also serve as a source of original information for the elaboration of lessons on catalysis for Master students.
