Simulation of an adiabatic packed bed reactor

A model has been developed for adiabatic packed bed reactors which includes all the intra-particle and interphase effects plus the additional effect of axial diffusion. The computer time required for the solution was considerably less than in earlier models. The technique is based on the application of the orthogonal collocation method to both the single particle and the external field, thereby reducing the whole problem into one of solving a number of simultaneous first order ordinary differential equations.
