Of intense interest both to academics and industry professionals, this groundbreaking book-length treatment of selective catalytic reduction of NOx using ammonia/urea includes papers by researchers at the leading edge of diesel exhaust abatement.

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.

The first treatment in book format of Selective Catalytic Reduction (SCR) Equally interesting to professionals and to academics Contains contributions from the leaders in diesel exhaust abatement Includes supplementary material: sn.pub/extras
