ABSTRACT
For a homogeneous reactor, it is characteristic that just one phase, usually a gas or a liquid phase, is present. Chemical reactions thus take place in this phase. This chapter examines three reactors most commonly used industrially for homogeneous reactions: a batch reactor (BR), a tube reactor, and a tank reactor. On an industrial scale, BRs are primarily intended for homogeneous liquid-phase reactions and less frequently for gas-phase reactions. On a laboratory scale, however, BRs with a constant volume are often used for the determination of the kinetics of homogeneous gas-phase reactions. The scaleup of kinetic data obtained in the laboratory to a BR operating on an industrial scale is fairly simple, as the reaction time in the laboratory corresponds directly to the reaction time on the factory scale, provided that the reactors in general operate under similar conditions. From the kinetic point of view, a BR is often presented as an attractive alternative.
