Abstract
The laminar-flow reactor considering radial dispersion for a species incurring first-order homogeneous (bulk) and heterogeneous (wall) chemical reactions was mathematically modeled. The equation was solved both analytically, and by the Crank-Nicolson finite-difference technique.
The response surface method was used to obtain the optimum values of the two rate constants. The optimum values interact because the wall and bulk reactions proceed in parallel. Varied reactor diameters serve to decouple the bulk and wall reactions to locate the true values of the rate constants.
Four dimensionless variables were defined and used to characterize the reacting system. In addition, their values were shown to determine the validity of the plug-flow model.
The reaction model was used in conjunction with experimental data to obtain the reaction rate constants for a system containing 1,1, 1-trichloroethane and excess hydrogen, at temperatures ranging from 555 to 681 °C.
