Reactor classification

Reactors may be classified by several different methods depending on the variables of interest. There is no single clear cut procedure for reactor classification. As a result, several of the more common classification schemes are presented here. 

The book is divided into five sections. Each section corresponds to a particular reactor classification. The classifications covered here are trickle-bed reactors, slurry system and stirred tank reactors, novel reactors, packed-bed and tubular reactors, and catalyst deactivation. 

Because of the variety of reactors available, some engineers believe that reactor classification is not possible. No matter how incomplete a classification may be, however, the designer needs some guidance, even though there may be some reactor types that do not fit into any classification. Accordingly, we will classify reactors using the following criteria ... 

To guide the reactor selection process, Walas [7] has classified reactions according to the operating mode (batch or continuous), reactor type (tank, tank battery, tubular), flow type (back mixed, multistage back mixed), and the phases in contact. This reactor classification in Table 7.2 indicates if a particular reactor arrangement is commonly used, rarely used, or not feasible.

There arc various classes of reactors. The three that are most encountered in practice are batch, continuous stirred tank (CSTR), and tubular. As such, they receive the bulk of the treatment. Another reactor reviewed is the serai-batch unit. Other topics reviewed include reactor classification, the conservation laws, and the comparison of reactors.
