Solution of dynamic distributed parameter model of nondiabatic, fixed-bed reactor
TL;DR: In this article, a new dynamic 1-D model, called the α-model, is presented, which is an excellent approximation to the dynamic 2D model and provides significant savings in computational time with minimal sacrifice of physical detail.

Axial Dispersion in Nonisothermal Packed Bed Chemical Reactors
TL;DR: In this paper, a criterion is developed to predict axial dispersion is important in nonisothermal packed-bed reactors with cooling or heating at the walls, and the criterion is applied to the experimental data presented by Schuler, et al. for SO2 oxidation on an alumina catalyst impregnated with platinum.

Orthogonal collocation in chemical reaction engineering
TL;DR: In this paper, the orthogonal collocation method is used to obtain approximate solutions to the differential equations modeling chemical reactors, which is very often useful in engineering work, where valid approximations are accepted.

Multivariable computer control of a butane hydrogenolysis reactor: Part I. State space reactor modeling
TL;DR: In this paper, a state space model is developed for an existing nonadiabatic packed-bed reactor which experiences axial and radial concentration and temperature gradients resulting from highly exothermic reactions involving several chemical species.

Singular perturbations of nonlinear boundary value problems arising in chemical flow reactors
L.B. Freeman,G. Houghton +1 more
TL;DR: In this article, the boundary value problem in a chemical flow reactor with axial diffusion was considered as a singular perturbation on the reactor flow and kinetics, and closed form approximations were generated for the axial concentration profiles.
