Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts

by Isabella Nova (Editor), Enrico Tronconi (Editor)

Urea-SCR Technology for deNOx After Treatment of Diesel Exhausts presents a complete overview of the 

selective catalytic reduction of NOx by ammonia/urea. The book starts with 

an illustration of the technology in the framework of the current context (legislation, 

market, system configurations), covers the fundamental aspects of the SCR process 

(catalysts, chemistry, mechanism, kinetics) and analyzes its application to useful topics 

such as modeling of full scale monolith catalysts, control aspects, ammonia injections 

systems and integration with other devices for combined removal of pollutants.

[Matti · Rating 3 out of 5]

The book was very thorough regarding the catalyst chemistry and its kinetics. That much so that some of the chapters felt more like review articles rather than book chapters. The different chapters were rather separate but still, if you wanted to know about zeolite SCR chemical modeling you still needed to read through the vanadium SCR modelling as the zeolite kinetics chapters refer back to the vanadium chapter regarding for certain kinetics concepts (e.g. redox kinetics). If only one part of the book is of interest, you can limit your reading to that part. The same applies to most chapters other than the kinetics chapters (for the abovementioned reason) .

Whereas the catalyst chemistry was very detailed, other parts of the SCR system (AdBlue dosing, mixing, approaches for control strategies) were given rather an overview look. That being said those chapters were quite good introductions on those matters as themselves.

As the book compiled of chapters of different authors and spans quite a wide subject area I've summarized below very short reviews about the different parts of the book:

Part I Selective catalytic reduction technology:
A short overview on the general subject area. Good introduction.

Part II Catalyst:
Overview of the SCR catalyst types used. Good Introduction.

Part III Mechanistic aspects and Part IV Reaction kinetics:
Very deep dive into the subject matter. It is very noticeable in this part that different chapters are written by different authors. These parts felt more like review articles rather than book chapters.

Part V Modelling and Control
This was a bit mixed chapter as it is both very deep and then at many points not deep enough to actually being able teach to use the presented models. Many part and subpart models were given but one would need to go through the references to be able to use them. As such the part serves as a sort of introduction to modelling.

Part VI Ammonia supply
A very good, rather concise and easy-to-read summary of the subject matter. It is rather basic, but still one of the best parts of the book which I would recommend for reading if one would like to have an overview. Regarding DEF mixing devices the part offers only one viewpoint of the matter. There are also other approaches.

Part VII Integrated systems
I enjoyed this part of the book. The balance of detail and general overview was good to be able to provide new information while still being rather easy to read.

Part VIII Case Histories
Chapter 21 (2010 Ford truck catalyst system) was very good giving a glimpse of the complete process involved in adopting SCR technology. It was great to have this chapter included into the book. Chapter 22 (Model-based approaches) on the other hand was in my opinion too short to be of much use (other than giving a very rough idea what is it about).
