Composition modulation is a method of operating a catalytic reactor to improve catalyst activity or selectivity and has been under study for more than 25 years. In the last few years, several commercial applications have been realized and more will certainly appear. A large international research literature now exists. This book examines this literature and attempts to organize and analyze it with the intent of identifying the magnitude of improvements possible, why modulation is effective, and what questions remain unanswered. Topics include hydrogenation, oxidation, reduction, and polymerization reactions for NOX, SOX, NH3, and hydrocarbons.

Energy: Money, Materials and Engineering focuses on the utilization and management of energy sources, taking into consideration the chemical processes and economic implications involved. Divided into eight parts with 47 chapters, the book features the literature of authors who have painstakingly conducted studies on the utilization, management, conversion, and the economics involved in the use of energy. These papers stress the contributions of chemical engineers and researchers in establishing the relationship of the development of energy sources, while at the same time minding their possible effects on the environment. In the conversion of energy, various processes are discussed. The book also touches the processes involved in the conservation of energy in various areas as well as in the industrial setting. Relative to this, various processes are discussed, including water electrolysis, the use of batteries in electricity supply system, coal gasification, and the use of turbines. The text also points out the evolution of hazardous materials because of the use of energy. The need to create programs to control their potential effects on the environment and health is stressed. The book is a valuable source of information for those involved in thermodynamics.

This book offers an overview of the state of the art in the field of DeNOx catalysis in order to focus novel orientations, new technological developments, from laboratory to industrial scale. A particular attention has been paid towards the implementation of catalytic processes for minimising NOx emissions either from stationary or mobile sources under lean condition to meet future standard regulations of NOx emissions. In the first part of this book, critical aspects reported in the literature which usually make difficult the achievement of efficient catalytic technologies in those conditions are summarised and analysed in order two separate new perspectives. The second part deals with fundamental aspects at molecular level. A better understanding of the reactions involved under unsteady-state conditions is probably a pre-requisite step for improving the performances of the actual processes or developing original ones. The development of powerful in situ spectroscopic techniques is of fundamental interest for kinetic modelling. Correlations between spectroscopic and kinetic data with those obtained from theoretical calculations are reported. Some illustrations emphasise the fact that these comparisons may help in determining the nature of the catalytic active sites and building predictive tools for simulations under running conditions. The latter part of this book will be illustrated by different practical approaches covering various aspects related to the catalysts preparation and the development of alternative technologies which include industrial considerations. - New technological developments for investigating catalytic reactions in transient conditions (in situ and operando spectroscopic techniques) - Concerted approaches in DeNOx catalysis - How academic aspects (kinetic, in situ spectroscopic measurements) can provide useful information for practical applications - Comparison of different approaches provided by academic and industrial partners
