O autorze

Andreas Seidel–Morgenstern received his PhD in 1987 from the Institute of Physical Chemistry of the Academy of Sciences in Berlin. Between 1991 and 1992 he worked as a postdoctoral fellow at the University of Tennessee in Knoxville. In 1994 he finished the Habilitation at the Technical University in Berlin. He has industrial experience with Schering AG (1995) and has consulted for various companies in the areas of separation science and reaction engineering. Since 1995 he has been Professor of Chemical Process Engineering at the Otto von Guericke University in Magdeburg. He was appointed to the position of Director at the Max Planck Institute for Dynamics of Complex Technical Systems in Magdeburg in 2002 where he leads the department "Physical and Chemical Foundations of Process Engineering". Among his numerous awards, he received the Max Buchner Award of Dechema in 2000, the Otto von Guericke Research Award of the Magdeburg University in 2002 and in 2008 he received an Honoris Causa Doctorate from the Lappeenranta University in Finland. His current research interests include reaction engineering, heterogeneous catalysis, preparative chromatography and Enantioselective crystallization.

The integration of porous and dense membranes in chemical reactors provides attractive possibilities to enhance the performance oft he reactor, e.g. an efficient selective removal of reaction products or the realization of optimized reactant dosing strategies. The latter approach, which permits improving selectivity and yield, is treated in this book. This authoritative work encompasses a broad spectrum of relevant topics and includes the basic principles of distributor–type membrane reactors, the analysis of relevant mass and heat transfer processes, experimental investigations for different types of membrane reactors and a comparison with classical reactors, all based on case studies and model reactions. The significant progress achieved over the last few years in this modern field of chemical reaction engineering is summarized in a competent manner including original material. The novice can grasp the elementary concepts and the professional can familiarize himself with the most recent developments in the area. For the industrial practitioner the book evaluates the potential for future applications.
