Transient Regime in a System of Flow Reactors

Heretofore, the kinetic models of the reactions proceeding in closed systems have been considered. In such systems material exchange with surroundings is excluded (batch reactors). In practice, many reactions are carried out in open systems under a regime of continuous feed of reactants to a reactor and withdrawal of formed 

2 Multi-Step Reactions The Methods for Analytical Solving the Direct Problem 

Let us consider a stirred tank reactor (STR). In such reactor, a reaction mixture is stirred in the way that current concentrations of reactants taking part in a reaction are the same at any time moment in any point of reaction space. Let the first-order B proceed in the STR. The solution of reactant A with a concen- 

Dividing the both parts of the equation by V yields the mathematical model of the STR in the form  

in contrast to the kinetic equation describing the first-order reaction in a batch reactor, the last equation contains the summand which characterizes geometrical dimensions of the reactor and the rate of substance feed to the reactor and its
