Membrane Reactors: Distributing Reactants to Improve Selectivity and Yield

This authoritative work represents a broad treatment of the field, including the basic principles of membrane reactors, a comparative study of these and conventional fixed-bed reactors or multi-tube reactors, modeling, industrial applications, and emerging applications -- all based on case studies and model reactions with a stringent mathematical framework. The significant progress made over the last few years in this inherently hot multidisciplinary field is summarized in a competent manner, such that the novice can grasp the elementary concepts, while professionals can familiarize themselves with the latest developments in the area. For the industrial practitioner, this practical book covers all important current and potential future applications.

About the Author :
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.
