Reactors can take various form depending on the nature of the feed materials and the products. Understanding the behaviour of reactors is necessary to properly control and handle a raction system. Basically, there are two groups of reactors, batch reactors and continuous flow reactors.

Continuous reactor - Wikipedia

Reactors can be divided into two broad categories, batch reactors and continuous reactors. Batch reactors are stirred tanks sufficiently large to handle the full inventory of a complete batch cycle. In some cases, batch reactors may be operated in semi batch mode where one chemical is charged to the vessel and a second chemical is added slowly.

Reactor Theory and Practice Batch Reactors. Batch reactors are examples of “closed reactors” that is ones that, once seeded or inoculated, receive no further inputs of mass or energy and permit no outputs of waste materials. Batch reactors may be stirred or not stirred but in any case, conditions in the reactor are constantly changing.
