Heat Management by Microdevices

This chapter is devoted to the discussion of thermal effects during chemical reactions with the main emphasis on how they can be controlled by using microdevices. A short introduction outlines the basic principles used in chemical reaction engineering without going into the details of thermostability of conventional flow reactors. The reader can find these topics in general text books on conventional chemical reactor design and engineering. 

Nearly all chemical reactions are accompanied by heat production or heat consumption. Therefore, strictly isothermal conditions are hard to attain in chemical reactors. Consequently, heat effects must be taken into account when evacuating or supplying heat to the reaction mixture. In general, a certain temperature range is specified in which the reactions have to be carried out in order to assure safe operation and to reach the desired product yield and selectivity at acceptable reactor performance. 

Different factors influence the choice of the temperature range for the chemical transformations, such as 

There are several means to facilitate the heat management of chemical reactors, such as
