✦ Synopsis

The application of the dispersion model of flow reactors for reactions of any order with two reactants and different initial concentrations yields a system of differential equations which can by considering the stoichiometry of the reaction be reduced to one differential equation.

The numerical solution of the differential equation discloses the influence of the stoichiometry and the different initial concentrations on the concentration profiles. For the important case of a Znd-order reaction, diagrams are presented which show the deviation of the concentration when the reaction is treated like a pseudo I St-order reaction. Since for the 1 St-order reaction the reactor outlet concentration can be calculated from the analytical solution, the prepared diagrams offer the possibility to determine the conversion for a 2nd-order reaction rapidly and without employing a computer.
