This book analyzes conventional fixed-bed reactors such as trickle-bed, bubble (packed) column, and multitubular reactors with regard to process efficiency, design and safety. It is shown that these reactors do not possess any substantial potential for improving industrial processes. Modern concepts in mass transfer, kinetics and process design are applied to process development. In light of the given analysis, new approaches to the development of technologies based on innovative principles are elucidated. For the first time, first-hand knowledge about Two-Zone Model, Oscillation Theory, map of the energy dissipation is presented in full.

Reviews the Two-Zone Model Alerts plant designers and others to the lack of potential for process enhancement in the framework of the traditional technological paradigms Presents oscillation Theory Formulates concisely the energy dissipation concept (energy consumption map) Explains in fullest form two multiphase fixed-bed technologies Includes supplementary material: sn.pub/extras Includes supplementary material: sn.pub/extras

Klappentext
Conventional Three-Phase Fixed-Bed Technologies analyzes conventional fixed-bed reactors such as trickle-bed, bubble (packed) column, and multitubular reactors with regard to process efficiency, design and safety. This book examines the shortcomings of these technologies with regard to the possibility of substantially improving industrial processes, applying modern concepts in mass transfer, kinetics and process design to process development.

In addition to this enlightening analysis, the author shares the most extensive first-hand knowledge to date of the Two-Zone Model, Oscillation Theory, and map of the energy dissipation. Finally, in light of the book's conclusions, a variety of new approaches to the development of related technologies based on innovative principles is explored.
