Chemical kinetics is an area that received perhaps most of the attention of chemical engineers from a parameter estimation point of view. Chemical engineers need mathematical expressions for the intrinsic rate of chemical reactions... 

From different disciplines, biotechnology and biocatalysis are seen from very dif ferent angles and perspectives (Figure 1.1). Chemistry and chemists emphasize a molecularly-oriented perspective dominated by compounds and transformations, whereas chemical engineering and thus chemical engineers favor a process-oriented perspective of reactions and processes lastly, biology and its practitioners contribute a systems-oriented perspective of description at the organism level as well as in their view of evolution. 

Several very useful books on the subject of chemical process development have been published.1 These have been written largely from the point of view of the bench chemist or chemical engineer. Emphasis in this collection of books is on the work needed to ensure that practical chemical reactions are created for scale-up, that the chemistry is understood, that the theory and mechanics needed to engineer scale-up are addressed, and that Safety, Environment and Food and Drug Administration requirements are met. 

The term reactive filtration may be used in a variety of applications. A simple search of the internet provides results such as reactive filter paper [1], adsorption filters for removing heavy metals from water [2], solid matrices used in organic synthesis [3], membranes for wastewater treatment, or even dialysis machines, filters for deep-frying pans and devices for the dechlorination of shower water by reaction with vitamin C. Most of the applications termed reactive filtration would be named heterogeneous catalysis or adsorption from a chemical engineer s point of view. 

The decomposition of AB material in solution could be attractive for many reasons. From a chemical engineering point of view, the use of a liquid fuel is generally preferred because of the simplifled transport compared to solid materials. Liquid AB hydrogen sources can be used to improve the controllability of the AB decomposition by separating the decomposition zone (reactor) from the storage tank. This measure would be an important improvement with respect to safety, since the dehydrogenation reaction potentially bears the risk of a thermal run-away due to its exothermic nature.
