Temperature and Energy Effects in Chemical Reactors

In order to achieve adequate control during the operation of a reactor, it is necessary to 

For nonisothermal reactors the key questions that the reactor designer must answer are (1) How can one relate the temperature of the reacting system to the degree of conversion that has been accomplished and (2) How does this temperature influence the subsequent performance of the system In responding to these questions the chemical engineer must use two basic tools—the material balance and the energy balance. The bulk of this chapter deals with these topics. Some stability and selectivity considerations are also treated. 

The principle that energy must be conserved has been expressed by innumerable textbook authors in a number of mathematical forms, 

Esys is the internal energy of a control volume or fixed region in space that has been chosen as the system to be investigated 

Q is the rate at which heat is being transferred to the system from the surroundings across boundaries that are impermeable to the flow of matter
